Inglet, Boyd S. "Cultivation of Mushroom Mycelia Using Whey Products as a Growth Substrate." DigitalCommons@USU, 2004. https://digitalcommons.usu.edu/etd/5522.
Full textAbstract:
As part of a project designed to utilize common dairy waste products profitably, reconstituted dry whey permeate and delactosed whey were tested as growth substrates for mycelia of the edible mushroom Lentinus edodes. This mushroom was chosen because it is possible to profitably cultivate it due to its popular culinary appeal and perceived medical benefits.
Growth experiments were performed in petri dishes containing either reconstituted dry whey permeate or delactosed whey as a growth substrate, and the measured response was the size of the growing mycelia colony. When reconstituted dry whey permeate was utilized as a growth substrate, the factors of substrate concentration, pH, and growth temperature were controlled in an effort to determine the optimal growth conditions for the mushroom mycelia. These conditions were determined by applying an analytical method known as response surface methodology (RSM). RSM is a collection of mathematical techniques that is able to determine optimal values for many variables run simultaneously in an experiment. Mycelia were also grown on delactosed whey at different substrate concentrations in an effort to determine if this substrate would be suitable for the growth of mushroom mycelia.
Results: RSM was successfully utilized to determine the optimal growth conditions for L. edodes when grown on reconstituted dry whey powder. These conditions were 40 g/L substrate concentration, pH 4 .97, and temperature 23.6°C Delactosed whey was successfully utilized as a growth substrate for L. edodes. However, delactosed whey concentrations above 40% v/v were lethal to the mushroom mycelia, suggesting a possible use for delactosed whey as a fungicide.

Full textAbstract:
Vast- quantities of lignocellulosic materials, representing potential substrates for the cultivation of speciality mushrooms, are produced annually in South Africa. A number of these materials are derived as waste products of the timber and agricultural industries, e.g. Maranti (Shorea spp.) and Port Jackson Willow (Acacia longifolia) respectively. The screening of various wood-degrading fungi, which are cultivated worldwide for their production of speciality mushrooms, indicated that under the environmental conditions considered, certain species were adapted to cultivation on these lignocellulosic wastes (Pleurotus species) whereas others were not (Lentinus edodes and Flammulina velutipes). Furthermore, intra- and interspecies specific differences in the growth and production potential of the various lignocellulolytic fungi investigated on synthetic and natural medium were discovered. Biochemical and genetical investigations of these strains indicated differences between and within species which were often significant. Species varied qualitatively and quantitatively in the lignocellulolytic enzymes produced, which was loosely correlated with productivity on the different media investigated. Genetical studies, using RAPD fingerprinting, indicated that the Pleurotus genus is highly variable which supports the observed differences in growth, yield and enzymatic activity between different strains and species.

Full textAbstract:
Improving food safety and food security is imperative to adequately feed a growing population that is expected to exceed 9 billion people by 2050. Mushroom cultivation provides unique opportunities to take advantage of underutilized resources and produce high-quality food from otherwise inedible or unsafe food sources. Pleurotus ostreatus is a ligninolytic and biotechnologically relevant fungus that can be cultivated on a diverse array of lignocellulosic byproducts. Prosopis spp. are abundant in the Sonoran Desert and broadly distributed in semi-arid to arid regions around the globe. Prosopis spp. legumes (pods), and approximately 25% of all commonly cultivated crops, are susceptible to aflatoxin contamination, a highly carcinogenic and potentially lethal mycotoxin. This work aimed to (1) identify novel lignocellulosic byproducts from the Sonoran Desert for use as substrate materials in Pleurotus ostreatus (oyster mushroom) cultivation; (2) evaluate the safety of mushrooms cultivated on plant products that are contaminated with aflatoxin; and (3) measure the amount of aflatoxin that is degraded by P. ostreatus after the contaminated products have been colonized by the fungus. Prosopis spp. pods were identified as suitable substrate component for P. ostreatus production by conducting yield evaluations and finding that the biological efficiency increased with increasing percentages of pods. No detectable quantity of aflatoxin could be measured in mushrooms that were cultivated on maize that was naturally contaminated with aflatoxin B1 at concentrations up to 2500 ng g⁻¹. P. ostreatus degraded AFB₁ by >85% in maize with initial concentrations of 2500 ng g⁻¹ AFB₁ in repeated experiments. Thus, the cultivation of P. ostreatus on aflatoxin-contaminated products may be a viable method to produce a safe and high quality food from an otherwise unsafe food source, and may double as a means to reduce the aflatoxin concentration in contaminated plant products to levels that are acceptable for use as livestock feed.

Full textAbstract:
Organics recycling is increasing in New England as multiple states have enacted laws to divert organic materials, including food scraps and food processing residuals, away from landfills. Anaerobic digesters on dairy farms represent an attractive approach to food waste recycling because existing infrastructure is in place and co-digestion of dairy manure with food waste can increase renewable biogas production. In addition, anaerobic digestion results in effluents that can be separated into solid and liquid residual materials, or 'digestates'. Screw-press separated solids consist of lignocellulosic biomass resistant to microbial degradation during anaerobic digestion. These separated solids are typically recycled on farms as animal bedding before returning to the digester, whereas remaining liquid digestates are typically spread as fertilizer for nearby feed crops or pasture fields. Within this model, anaerobic digestion is not a nutrient management solution and repeated land application of digestate nutrients can create eutrophication risk over time. Alternative models are needed where digestate materials are converted into valuable products to be sold off-farm, enabling the removal of nutrients to help meet nutrient management goals. In this thesis, I address two research questions related to the pursuit of such alternative models. First, how do physicochemical characteristics of digestate materials vary across full-scale systems in the region, including systems with and without food waste as a substantial proportion of feedstock, and how do these variations affect the potential for conversion of digestates into valuable products (e.g., soil amendments)? Second, can separated digestate solids be used for commercial cultivation of gourmet oyster mushrooms (Pleurotus ostreatus) to produce food for human consumption, providing synchronous nutrient recovery and food production? Results from my first research chapter indicate that increasing food waste inputs (and thus diversification of feedstock recipes) will likely increase the variability of some solid and liquid digestate characteristics and can result in greater contamination with synthetic particles, with implications for nutrient recovery efforts and associated products. My second research chapter shows that screw-press separated digestate solids can offset non-local substrate ingredients to a degree while achieving oyster mushroom yields comparable to commercial recipes. Furthermore, this strategy could divert nutrients away from land adjacent to digesters and directly into safe, nutritious, protein-rich food for humans, while also producing a useful spent mushroom substrate product.

Previous issue date: 2008-05-30<br>Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>There is in the Amazon region a great amount of residues (wood, agro-forest and agroindustrial), which has been underestimated, and constitutes potential sources for the
cultivation of edible fungi in the region. The biodiversity of the Amazon draws the worldwide interest about its resources, specially for the microorganisms with potential for commercial use. Amongst these organisms there are the edible and medicinal mushrooms. In this way, the cultivation of edible mushrooms in the state of Amazon could represent an
alternative source for the regional development. Thus, this research had the objective to test the development of different wild edible mushroom species, as well as testing the use of
different regional residues in the substrate composition for their cultivation. Preliminary tests were carried out with the species Pleurotus ostreatus, Lentinus strigosus, Polyporus arcularius and with five wood residues (marupá, pau de balsa, amapá doce, muiratinga and breu) and two of agro-industrial origin (sugar cane bagasse and the stem of pupunheira palm tree). In this experimental phase the micelial growth of the fungi in substrates made from the above residues was evaluated. In the subsequent tests, based on the results obtained in these
preliminary tests, Pleurotus ostreatus, two wood residues (marupá and pau de balsa sawdust) and two agro-industrial ones (sugar cane bagasse and stem of pupunheira palm tree) were chosen. All the substrates were supplemented with a mixture of cereal brans (rice, wheat and corn), were evaluated for: 1- production of basidioma (yield), productivity, through the
biological efficiency of formulated substrates, loss of the organic matter, biological behavior of the strain (period of colonization, primordia formation and production of basidioma)
referred in Chapter 2; 2- Mineral composition of: the raw material, the initial and spent substrates (post-harvest), and of the mushroom (Chapter 3); 3 - Nutritional composition of:
the mushroom, the raw material and substrates (Chapter 4). In general, it can be concluded that the strain of P. ostreatus has developed in a satisfactory way in all tested substrates,
making it possible to use these residues (with low or no commercial value) in the mushroom cultivation. Moreover, it is an ecologically correct use of the residues, since it prevents the
discard of these residues in the environment, promoting the bioconversion into added-value product edible mushroom and of high nutritional value, and that could become a source of
regional sustainable development<br>Há na região amazônica uma grande quantidade de resíduos (madeireiros, agroflorestais e agroindustriais), cujo quantitativo tem sido subestimado, os quais constituem fontes potenciais para utilização no cultivo de fungos comestíveis na região. A riqueza promovida pela biodiversidade da Amazônia começa a despertar interesse mundial a cerca de seus recursos, com acentuada atenção para os microrganismos com potencial de utilização comercial. Dentre estes organismos encontram-se os fungos comestíveis e medicinais. Desta forma, o cultivo de cogumelos comestíveis no estado do Amazonas, poderá representar uma fonte alternativa para o desenvolvimento regional. Assim, esta pesquisa teve por meta testar o
desenvolvimento de diferentes espécies de cogumelos comestíveis nativos, bem como testar o uso de diferentes resíduos regionais na composição de substratos para o cultivo dos mesmos. Foram feitos inicialmente testes preliminares com as espécies Pleurotus ostreatus, Lentinus strigosus e Polyporus arcularius e com cinco resíduos madeireiros (marupá, pau de balsa, amapá doce, muiratinga e breu) e dois de origem agroindustrial (bagaço cana-de-açúcar e estipe de pupunheira). Nesta fase experimental avaliou-se o crescimento micelial das espécies fúngicas em substratos à base dos resíduos anteriormente citados. Nos testes subseqüentes, com base nos resultados obtidos nestes testes preliminares, escolheu-se o P. ostreatus, dois resíduos madeireiros (marupá e pau de balsa) e dois agroindustriais (bagaço de cana-deaçúcar e estipe de pupunheira). Todos os substratos foram também suplementados com uma mistura de farelo de cereais (arroz, trigo e milho), sendo avaliados: 1- produção de basidiomas (rendimento), produtividade, através da eficiência biológica dos substratos formulados, perda da matéria orgânica, comportamento biológico da linhagem (período de colonização, de formação dos primórdios e de produção dos basidiomas) abordados no Capítulo 2; 2- Composição mineral da matéria-prima, dos substratos iniciais, residuais (pós-colheita) e do cogumelo (Capítulo 3); 3- Composição nutricional do cogumelo, da matéria-prima e dos
substratos de cultivo (Capítulo 4). De uma forma geral, conclui-se que a linhagem de P. ostreatus desenvolveu-se de uma forma satisfatória em todos os substratos testados, o que
viabiliza o uso destes resíduos (com baixo ou nenhum valor comercial) para a fungicultura. Além disso, é uma aplicação ecologicamente correta, uma vez que evita que estes resíduos
sejam descartados na natureza, permitindo-lhes a bioconversão em um produto de valor agregado cogumelo comestível e de elevado valor nutricional e que poderá vir a tornar-se
uma fonte de desenvolvimento sustentável regional

Full textAbstract:
碩士<br>國立勤益科技大學<br>冷凍空調系<br>106<br>Mushrooms have been one of extensively edible food, the drug effect and ingredients have been validated in related academic theses. Different mushrooms are characterized by rich fibers and low heat content. This study aims to build ideal conditions, looks for the optimal growth temperature and humidity for different mushrooms, and checks which variables influence the growth of mushrooms most significantly, so as to establish the optimal growth curve.
The mushroom spawn-run temperature is set as 24℃~26℃, the humidity is 60%~70%, the spawn-run takes about 45 days. When the hyphae spread over the cultivation waste bag completely, meaning the spawn-run is finished. This experiment uses 18℃, RH80%~90% and 20℃, RH80%~90% to compare the growth temperatures. The common ground is that the mushroom will not grow out 2 days~3 days before the spawn-run is completed, but there is fast growth stage, the duration is 12 days~13 days, the optimal growth height at 18℃ (mushroom cap not turned up) is about 18cm, the optimal growth height at 20℃ is about 15cm, meaning low temperature growth can prolong the almond abalone mushroom growth time, the length is increased.
The moisture content becomes stable in 5HR of vacuum drying and vacuum freeze drying experiments, the moisture content is 10%~15%, the minimum value is 3.8%. According to the experimental results, the minced forms have the lowest moisture content, which are 0.2cm, 0.4cm, 0.6cm and 0.8cm. According to this experiment, the minced dry area accounts for the largest proportion of volume, so the moisture content after drying is lower. Therefore, the dry area accounts for larger proportion of volume (1/cm), the moisture content is more likely to be lower.

However, if mushroom companies would like to gain an early foothold and thus leading to technological know-how and experience in the subsequent product and market maturity stage, an early investment is necessary and the payback period will have to be extended for 10 years. From a long-term investment perspective, this project is financially feasible.

Full textAbstract:
Shiitake (Lentinula edodes (Berkeley) Pegler) produces an edible mushroom that has been cultivated for centuries in China, Korea, Japan, Singapore, Thailand and other Asian countries. Shiitake mushrooms grow naturally on decaying wood of hardwood trees and have traditionally been grown on short lengths of freshly-cut logs. Until now, there has been no serious exploration of the potential for Australian forest owners to utilise small logs of native or plantation forest species for shiitake mushroom production, such as eucalypt (Eucalyptus spp.).<br>Logs of six tree species were harvested from farm forestry plantations in Victoria and inoculated with shiitake infected dowels imported from the United States. Over the course of the next 18 months the logs were soaked four times to initiate fruiting. The fresh mushrooms were harvested and weighed to allow a comparison between log species and size. A sample of the mushrooms from each log species produced in the 2nd and 3rd fruiting were tested for their protein and fibre content.<br>Quercus robur was the most productive species. Over the course of the trial (four frutings) the oak logs produced almost 1 kilogram of fresh mushrooms per log which was significantly more than E. cladocalyx (527 g/log) and Alnus glutinosa (465 g/log) and Eucalyptus nitens (389 g/log) which were all, in turn, significantly more productive than Populus sp. (140 g/log) and Acacia melanoxyon (98 g/log). Larger logs produced more fruit although this may have been related to the greater number of inoculations. The protein and fibre content of mushrooms produced from shining gum logs was slightly lower than that from the oak logs but greater than that from alder. Sugar gum mushrooms had the lowest protein content.<br>The research suggests that there is potential to use eucalypt logs thinned from young fast-grown farm plantations as the basis for a log-based shiitake industry although more work is required to test the marketability of eucalypt grown shiitake and the economic viability of small scale production units.

Situated within feminist geographic debates regarding gender and work, this thesis argues that normalized and stereotypical understandings of gender, ethnicity, and immigrant status have become tools of discipline that encourage particular performances of work within mushroom houses. The disciplinary strategies explored in this thesis are comprised of rules, procedures, regulations, and dispositions, and are deployed in a complementarily manner to maximize profit generated by laborers.

Thesis, 2019. http://ndltd.ncl.edu.tw/handle/7u4bav.
Full textAbstract:
碩士<br>靜宜大學<br>食品營養學系<br>107<br>Soybean hulls are the important by-product of soybean oil production. Because of high fiber content, but low protein content, soybean hulls were added to the feed of ruminants, and less used in other application. In order to increase utilization of the under-utilized byproduct, technology of Pleurotus eryngii cultivation by replacing sawdust with soybean hulls were developed in our laboratory. In this study, spent substrates after fruit body harvesting were assayed for antioxidant activities and antioxidant substance contents to evaluate the reuse application. In addition, solid-state fermented soybean hulls by Phellinus linteus in a plastic bag were also carried out. Antioxidant activities and antioxidant substance contents of solid-state fermented mycelium were determined to develop a new fermented product. Firstly, P. linteus were cultivated in a plastic bag to realize the radial and axial growth of mycelia with soybean hulls. Full confluency of mycelium growth was observed at the 30th day of culture. Then fermented soybean hulls were freeze-dried and extracted by 50%, 70% ethanol solution and hot water(100℃) for further assays. The antioxidant activities of extracts were measured by the methods of DPPH-, ABTS-free radical scavenging activity, and ferric reducing power. The antioxidant substance contents were determined of total phenolic and flavonoid contents. The results showed that DPPH radical scavenging activity, reducing power and antioxidant substance contents of fermented soybean hulls were higher than that of unfermented soybean hulls. The added value of soybean hulls was increased by solid-state fermentation of mycelium in a plastic bag. Mushroom farmers will also produce mycelium-based materials in Taiwan. For evaluation the reuse application of spent substrates of P. eryngii cultivation, spent substrates by replacing sawdust with 75% soybean hull and 25% wheat bran were collected after harvesting. Then antioxidant activities and antioxidant substance contents were assayed according to the method described previously. The results showed that all the antioxidant activities of spent substrates were lower than that of fresh substrates, and antioxidant substance contents of both substrates were not high enough. In the future, other bioactivities of spent substrates can be further evaluated for application such as immunity stimulation, feed conversion rate, where much remains to be developed.

Full textAbstract:
碩士<br>國立中興大學<br>園藝學系<br>87<br>The experimental results showed that the yield, fruiting and biological efficiency of the both mushroom species cultivated in the front, middle and rear parts and also at different shelves were not significantly different indicating the uniformity of environmental factors in the container. It proved that the humidity, temperature and carbon dioxide concentration in the container can be well controlled with the air-conditioning facilities designed and installed by the Taiwan Agricultural Research Institute. Both average yield and biological efficiency of the common white mushroom grown in the cargo container installed with air conditioning facilities were higher than those of the same mushroom species grown in the conventional mushroom house installed only with a temperature controlling equipment. The average yield and biological efficiency were 15.3 kg/m2 and 65.2% in the former case, while 12.6 kg/m2 and 48.2% in the latter one. When growing the king oyster mushroom the yield, fruiting and biological efficiency grown in the container from June 1998 to May 1999 were 174.2 g/bottle, 74.4% and 68.4% respectively, while those grown in the traditional mushroom house without an air conditioning facility were 117.6 g/bottle, 50.2% and 46.1% respectively. According the above experimental results it is concluded that the modified environmentally controlled cargo container can be used for growing both the above two mushroom species in hot seasons. Besides, even in the cold seasons the yield of the king oyster mushroom obtained in the containers was higher than that in the conventional plastic mushroom house showing the suitability of the modified container to mushroom cultivation.

Full textAbstract:
碩士<br>大仁科技大學<br>食品科技研究所<br>98<br>As to the substrates which were adopted by mushroom cultivation in Taiwan, most of those were based on sawdust for major ingredients, but after harvesting fresh mushrooms, so troublesome to cope with were abundant spent substrates that a few growers threw away those at random and then brought about environmental burdens as well as pollution. Consequently, it is urgent to pursue viable methods for making spent substrates reuse.
The research blended and recycled the spent substrates which were applied to Pleurotus citrinopileatus, P. ostreatus, Agrocybe aegerita, and first flushing P. eryngii with a view to exploring the practicability of developing Pleurotus eryngii. In the preliminary study, the optimal conditions for the cultivation of Pleurotus eryngii with solid-state medium in Petri dish were determined by Response Surface Methodology (RSM), including water extracts from different proportions of distinct mushroom spent substrates that substituted for fresh sawdust, different concentrations of water extract, and initial pH. Moreover, RSM could not only comprehend the optimal conditions of cultivating Pleurotus eryngii with the spent substrates but also provide the accordance for modulating spent substrate of mushrooms in the future and indeed developing solid-state cultivation of Pleurotus eryngii with plenty of polyethylene bags. The results showed that the highest biomass was obtained by incubation for 21 days when combining water extract which was derived from 50% spent substrates instead of fresh sawdust, water extract at a concentration of 60%, and initial pH 6.4. Solid state cultivation of P. eryngii is observed by replacing the sawdust component of substrates, either partially or entirely, with spent substrates of specific mushroom, including Pleurotus eryngii, P. citrinopileatus, and P. ostreatus. Results indicate that when 75% spent substrate replaces the fresh sawdust of the substrate（Pa-group）, primordial formation time of P. eryngii is faster than those of other experimental groups. Moreover, fruiting time of the Pa-group is considerably greater （p &lt; 0.05） than the group which uses the full amount of spent substrate to cultivate （Pg-group）, and is closer to the fruiting time of the control group. Although biological efficiency and yield of Pa-group are less than that of the control group, they are still undoubtedly higher than the experimental group, which utilizes spent substrates totally. Therefore, recycling spent substrates as an aid to mushroom growth holds great value. Furthermore, more researches need to be done to investigate ways, for instance, regulation of the composition of substrate for enhancement of yield and biological efficiency.

Full textAbstract:
碩士<br>靜宜大學<br>食品營養學系<br>106<br>In recent years, the Taiwan mushroom industry has been facing two serious problems, which are the shortage of sawdust and treatment of spent mushroom substrates. This study is going to develop a mushroom cultivation technology by replacing sawdust with soybean hulls. Then sawdust will not be used in mushroom cultivation by the mushroom farmers in the future. And spent soybean hull-based substrates can be recycled by the soybean oil manufacturers, to develop novel fermented feed. These two problems can be solved at the same time. In the study, soybean hull-based substrate was used for mycelial growth test firstly with seven kinds of edible and medicinal mushrooms, which are Lentinula edodes, Pleurotus eryngii, Hypsizygus tessellatus, Volvariella volvacea, Phellinus linteus, Ganoderma lucidum and a white strain of Auricularia fuscosuccinea. The results showed that all the mentioned mushrooms could grow well in soybean hull-based substrate. Additionally, mycelial radial growth test in petri dish and axial growth test in tube were carried out by P. eryngii and P. linteus with soybean hull-based substrates that could simulate the growth of mycelium in the plastic bags. As a result, the radial and axial growth rates in soybean hull-based substrates were similar to those of control group in sawdust-based substrate. Eventually, P. eryngii was cultivated in plastic bag for fruiting body production with soybean hull-based substrate to compare with sawdust-based substrate. The results showed the fruiting body yield per bag on average in soybean hull-based substrate and sawdust-based substrate reached 311.9 g and 304.65 g, respectively. The biological efficiency in soybean hull-based substrate was 57.71%, and that in sawdust-based substrate was 62.92%. Hence, Pleurotus eryngii cultivation was successful by replacing sawdust with soybean hulls. For the further research, the larger-scale cultivation will with soybean hull-based substrate be required in order to understand the yield stability. These results of this study would be beneficial to promote a win-win business model for soybean oil manufacturers and mushroom farmers.

Full textAbstract:
碩士<br>國立屏東科技大學<br>生物機電工程系所<br>103<br>In recent years, due to the rise of the concept of environmental conservation, thus influencing timber production decrease and make the sawdust prices increase. Indirect effect to the industries of mushroom that use sawdust as the main raw material, lead the mushroom price growing every year. Because Taiwan is located in subtropical region, and banana is one of the major valuable fruit, in addition planting area of banana in Taiwan accounted up to 11,000 hectares. After harvesting, the part of pseudostems were often dumped or burned in the fields, not only causing great waste of natural resources, but also making the ecological environment pollution. Oyster mushroom (Pleurotus ostreatus) is one of Taiwan's five economic edible mushrooms, therefore, this study will explore the feasibility of banana pseudostem agro-waste recycling used as oyster mushroom cultivation bag medium. In this study used five different banana pseudostem-sawdust mixtures for production of mushroom cultivation bag media, the ratio are 0%, 25%, 50%, 75% and 100%, respectively. Banana pseudostem-sawdust mixtures were assessed and determined of the best ratio, this study expects to achieve fully replace the traditional cultivation bag sawdust. The best ratio was determined by detection of the basic ingredients of cultivation bag, including: ash content, lignin content, cellulose content, total carbon content, total nitrogen content and spawn running days, as a follow-up analysis basis of cultivation bag productivity, biological efficiency and persistence.
The results showed that the fastest spawn running days revealed in control group is 21.5±0.5 days, followed by cultivation bag mixed with 25% of banana psrudostem, is 22±0.0 days; slowest revealed in cultivation bag which contains 100% banana pseudostem is 28±1.0 days.
Correlation coefficient for comparison the basic ingredients and spawn running days, observed correlation coefficient highest revealed at cellulose is 0.996; in the part of correlation coefficient for comparison C/N ratio and spawn running days, observed correlation coefficient is -0.809, slightly lower than the lignin and cellulose.
This study showed that, using a higher proportion of banana pseudostem would affect cultivation bag total nitrogen content, it would causing spawn running days got longer and increased the chance of cultivation bag attacked by contaminants. Using banana pseudostem replace 25% of the sawdust in cultivation bag could reduce sawdust consumption, not only could reduce the rate of pollution, but also effective provided a new way for consumption banana pseudostem.

Full textAbstract:
碩士<br>國立中興大學<br>動物科學系所<br>98<br>Recently, agricultural by-products have been successfully used in diets for animal and which is getting more popularly. Usually, by-products offer a lower price than do traditional feedstuffs so that it is possible to reduce the rising feed cost without compromising animal performance if the products are used carefully. Mushrooms have the ability to degrade lignocellulosic substrates such as lignins, celluloses and hemicelluloses by their enzymes to simpler molecules so that after the cultivation process the mushroom cultivation residues (MCR) are still having readily degradable fibrous materials and may be one of the choices among the by-products that contain available nutrients for feeding ruminants such as goats. The purpose of this study was to determine the feasibility of using MCR as a forage source in the diets for growing goats. Both of two experiments using completely randomized design with 8 female Nubian goats for 4 dietary treatments. The first and the second experiment were used MCR as replacement of pangola hay (PH) and corn silage (CS), respectively. The replacement ratios of MCR to PH or Cs were 0:50, 25:25, 35:15 and 50:0 thereafter each treatments along with 50% concentrate on dry matter (DM) basis. Diets containing MCR as replacement of CS resulted in more DM intake than that containing no MCR. Similarly, goats fed with diets containing 25% or 35% MCR as replacement of PH resulted in increase of DMI. The results revealed that goats fed with diets containing 0%, 25% or 35% MCR as replacement of PH were not different in nutrient digestibility and similar results also found in goats fed MCR as replacement of CS. In contrast, goats fed with 50% MCR were lower in digestibility of DM, organic matter, crude fiber, NDF, and ADF. Nitrogen (N) intake and N balance were significantly greater in goats fed with rations containing 35% MCR as replacement of CS but there were no longer true in goats fed with MCR in replacement of PH. Average daily gain (ADG) was significantly greater in goats fed with diet containing 25% MCR in replacement of PH but there were no longer better in goats fed with MCR in replacement of CS. However, it tended to be increased of ADG in goats fed with diets containing 25% or 35% MCR in replacement of CS. Feed conversion ratio was significantly better in goats fed with diet containing no MCR but it was not different in goats fed with diets containing various levels of MCR in replacement of CS. The ruminal total VFA content was not altered in the goats fed with MCR in replacement of CS but was different in goats fed with MCR in replacement of PH from those fed with no MCR. In conclusion, mushroom cultivation residues may be a good alternative resource for substituting conventional feedstuffs for feeding goats if they are properly used since high level mushroom cultivation residues containing diets may result in limitation of nutrient digestion and consequently growth performance of the animals fed with.

Full textAbstract:
碩士<br>亞洲大學<br>資訊工程學系<br>106<br>In the past, people only paid attention to the output and price of agricultural products, but in nowaday people begin attention to the quality of agricultural products and food safety issues.
Because people are beginning to pay attention to the quality of agricultural products and food safety issues, so the traditional management ways of farming and greenhouse cultivation can no longer that meet the needs of the present place.
Therefore, many agricultural producers started to adopt the automated production management technologies of "Industry 4.0", for example, using the "Internet of Things" technology to monitor the greenhouse and then use "Cloud Computing" and "Big Data Analysis" together with "artificial intelligence" Turn greenhouse management into a fully automated, ... way to improve the quality of crops and address consumers' worries about food safety.
In this paper, we reseach how to cultivate edible / medicinal mushrooms by using "Mushroom House".
Manufacturers are so always reduce costs as the main requirement, that they using the traditional method implement to this IoT monitoring system.
Therefore on this system only one temperature and humidity sensor, a CO2 sensor and a microcontroller, and a server host are used Provided to the user to monitor and record the environment control mushroom house. However, they always neglected the most important system's fault tolerance and the security of data storage. If only one device in this system fails, the system will be paralyzed.
This will result in a significant loss of the mushroom production line and a serious error in artificial intelligence and big data analysis.
This study explores how to use a combination of temperature and humidity sensors and CO2 sensors with multiple microcontrollers, networking-enabled microcontrollers and embedded systems (Raspberry Pi), x86-based servers, NAS (Private cloud) and free the cloud computing of a database (ThingSpeak) and a number of other devices that can be individually operated and provided for users to control the temperature, humidity and CO2 monitoring, recording and inquiry and other services within the environment. In this way, we can reduce the risk of paralysis caused by a single device failure and enhance the system's fault tolerance and data retention. Finally, we can improve the efficiency of mushroom house management and reduce the cost of mushroom production cost.

The only mushroom produced in Swaziland is Pleurotus ostreatus and the substrates commonly used are grass straw and maize stalk and cobs which are grazed by livestock interchangeably during summer and winter respectively. The study aims at evaluating yield response of P. ostreatus and P. eryngii when cultivated using sugarcane bagasse as substrate at various nutrition levels of corn powder and rice bran in the same cultivation conditions. Mycelial growth of the two mushrooms was tested at different temperatures, pH levels and nutrition supplement levels of substrates. Effect of different temperatures (p=0.05) on mycelial growth cultivated on PDA agar plates was significantly different for both mushrooms on the sixth day. For P. ostreatus the range was 37.9-88.9 mm with best growth diameter observed at 26, 28 and 30˚C while for P. eryngii mycelial growth diameter range was 22.8-67.6 mm where it was best at 26 and 28˚C and both had the lowest growth at 32˚C. Effects of pH were also significantly different on the sixth day where
IV
unadjusted PDA was better for both mushroom mycelial growths. The range was 58.3-88.7 mm and 34.1-69.1 mm for P. ostreatus and P. eryngii respectively. In adjusted condition, P. ostreatus favored pH 7 for growth, followed by 5, 6 and 8, and P. eryngii mycelial growth favored pH 7, followed by pH 6, then pH 5 and 8 with pH 4 being the least performing for both mushrooms. There was also significant difference between mycelial growths in the substrate tubes with various levels of nutritional supplements on the twenty first day. The range was 66.8-91.6mm in length and 40.5-64.2 mm for P. ostreatus and P. eryngii respectively. The sawdust substrate was best for both mushrooms mycelial growth at the various levels of nutrient treatments. In experiment 1 when temperature was maintained between 17-19oC there was no significant difference between substrates with various nutritional supplements in the average yield per bag of P. eryngii where the range was 38.30-62.86 g/bag and 33.01-55.51 g/bag for flush 1 and 2 respectively. For P. ostreatus there was significant difference in the first 2 flushes and no significant difference in the third flash. The range was 62.76-125.47 g/bag, 31.58-51.66 g/bag and 11.0-27.12 g/bag for flushes 1, 2 and 3 respectively. Sawdust substrate exhibited lower yield in the first and third flush. The flushing interval was 6 days and 14 days interval for P. ostreatus and P. eryngii respectively. In experiment 2 when temperature was maintained between 21.5 and 22oC the P. eryngii did not produce fruiting bodies. P. ostreatus yield of 3 flushes ranged from 43.9-177.7 g/ 4bags, 76.33-203.3 g/ 4 bags and 80.33-187.5 g/4 bags for the flushes 1, 2 and 3 respectively cultivated on sugarcane bagasse. Treatment 3 had the highest average yield for all flushes. P. eryngii can be cultivated in winter in Swaziland where average temperatures are usually 12oC. Both mushrooms can be cultivated using sugarcane bagasse as a substrate supplemented correctly with corn powder and rice bran at optimum temperature and pH levels.

The analysis can determine the effect of cultivation room environmental control and be reference of system performance improvement.The major environmental parameters include dry bulb temperature, wet bulb temperature, carbon dioxide concentration, air flow speed, lighting illumination. The measuring locations are marked in X, Y, and Z axis and refer to mushroom shelves location in order to collect actual environmental parameter in mushroom cultivation rooms. The mushroom cultivation rooms install heat insulation board to resist heat load and interdict indoor cool air releasing to outdoor. The cool air is delivered from bottom to top and absorbs exhale heat from mushrooms. To maintain high humid condition, applies twin flow nozzle humidification. Because of the character of the gas, the concentration of carbon dioxide is higher at lower level. In order to achieve actual environmental control of mushroom cultivation room and reduce labor cost of managing mushroom cultivation rooms, computerized automatic control should be apply. After analyzing measuring data, the twin side returning air flow mode is the best air circulation for mushroom cultivation room because the mode is the closest to setting condition and most suitable for cultivation.

The Contents of Abstract in This Thesis：
Hericium erinaceus (Bull. ex Fr.) Pers. is a traditional edible and medical mushroom in China, with common names such as Lion’s Mane, Monkey’s Head or Houtou mushroom. Due to the demand of fresh mushroom of H. erinaceus for human health care in recent years in Taiwan, the cultivation of Houtou mushroom increases year after year. Most of the cultivation has been conducted under non-air-conditioned culture room, and limits the harvest period from early winter to end of spring. Therefore yield and quality of Houtou mushroom are varied depending on climate and culture technology. This research was focused on cultural characteristic of H. erinaceus, recycling of used waste sawdust for decreasing the sawdust supply and promoting the cultivation technology of nutrient supplement and culture management for cultivation of Houtou mushroom. On PDA medium, H. erinaceus mycelia grow well at 24~28℃ of temperature and at pH 5~6. In screening of suitable materials for spawn, sawdust and Job’s tear are better than wheat grain in mushroom production. The yields of mushroom of first flush between 5 isolates of H. erinaceus cultivated on sawdust with bag culture are not different significantly. The mushroom yields of H. erinaceus are also not significantly different between PP plastic bag culture and bottle culture. Comparing the sawdust culture substrates of hardwood (of Acacia confusa), and soft wood ( of Thuja plicata), and the mixtures of various proportions of hardwood and soft wood, the mixture sawdust of 50% both hardwood and soft wood, for mushroom yield of H. erinaceus from three flushes in the biological efficiency(BE), is the best with more than 70% when cultivated at 18~20℃ is the effect of on stimulation of mushroom development, the whole fullness of pine sawdust substrate was found best 68% with BE (biological efficiency) from two flushes’ yield of Houtou mushroom that cultivated at 18~20℃. Comparing composted new sawdust to the recycled ones, the BE of first flush yield of mushroom in all sawdust substrates are not different significantly. In the recycled waste sawdust for cultivation the Houtou mushroom, all of the recycled sawdust got the BE of first yield, higher than those of new sawdust, one even reached 33% of BE. Comparing the composted recycled sawdust to the noncomposted, the noncomposted one has 34% BE, which was 40% higher than the composted new sawdust materials. Comparison of the sawdust recycled from different mushroom production, among the Maitake mushroom (Grifola fzondosa), Nameko mushroom (Pholita nameko), King Oyster (Pleurotus erynqii), Himematsutake mushroom (Aqaricus blazei) and Houtou mushroom, the sawdust containing 50% King Oyster waste sawdust had 33% BE, that was 40% better than the new one, and the results also showed that sawdust used by Houtou mushroom production were the better recycle for cultivating Houtou mushroom than those used by other mushrooms, with 20% ~ 40% increase in BE, respectively. In nutrient supplement, 6%、8% or 10% rice bran added to pine sawdust culture substrates all increased the yields by 20% or more. Comparing the effects of corn powder rice bran and wheat bran supplemented in different contents of pine sawdust on mycelial growth of Houtou mushroom, the results showed that corn powder supplements were superior to other nutrient supplements, and the more content of corn powder added the better the mycelia grow. In the effect of supplemented to pine sawdust culture substrate on mushroom yield, 3% Pangolagrass chicken manure compost was higher than that of 1%, 5% supplements or no supplement effects of pH valued and water contents of pine sawdust culture substrates on mycelial growth in glass tube and yield of mushroom in bottle culture, the Houtou mushroom mycelia grew well at pH 5.8~6.4 and fruiting body developed at pH 5.8 and 5.9 with 39.8% and 42.5% of BE, respectively Houtou mushroom grows its mycelia and develops its fruit bodies better at higher water content of sawdust substrates than at lower ones. It got 51% of BE in first flush production at 72.2% water content. When H. erinaceus was cultivated on pine sawdust culture substrates in PP-bottle, it took 30 ~ 34 days from inoculation to harvesting mushroom in all different pH values or water contents of sawdust culture substrates.

Dissertação de Mestrado em Biodiversidade e Biotecnologia Vegetal apresentada à Faculdade de Ciências e Tecnologia<br>Atualmente dependemos dos fungos num sentido mais amplo, devido ao seu papel como decompositores, mas também em assuntos mais específicos, especialmente relacionados com a agricultura e medicina. Assim, este trabalho focou-se em abordagens biotecnológicas relativas ao isolamento, cultivo e potencial antioxidante de fungos, com especial ênfase em Laetiporus sulphureus, um cogumelo comestível com propriedades organoléticas interessantes.Primeiramente, foram isolados vários fungos com valor comestível/medicinal da região (e algumas estirpes comerciais), com ênfase em Laetiporus sulphureus. Isto resultou na constituição de uma biblioteca micológica apelidada de Coleção Micológica de Coimbra (MICOI), atualmente composta por 29 isolados de fungos, 8 de Laetiporus sulphureus. Os resultados obtidos suportam o método de conservação usado (submersão em água destilada à temperatura ambiente), que se provou eficaz na manutenção de espécies saprófitas até 5 anos, mas é um método incerto, especialmente para espécies micorrízicas.De seguida, o crescimento miceliar de Laetiporus foi avaliado em meio PDA, de modo a selecionar uma estirpe para cultivo com uma taxa de crescimento alta. Foi escolhida a estirpe MICOI_23, mas o cultivo em diferentes substratos não levou à ocorrência de frutificação. No entanto, no tratamento de indução com choque frio, foram observadas formações miceliares distintas. O cultivo de Laetiporus parece ser bastante seletivo no que toca a estirpes e tendo em conta que apenas existe um caso de cultivo com sucesso, muito está ainda por melhorar. Por fim, a atividade antioxidante de estirpes de Laetiporus foi avaliada, recorrendo aos testes ABTS, FRAP e Folin-C. Antes dos mesmo, o crescimento miceliar em PDB foi testado de modo a compreender a cinética e a delinear as fases de latência, crescimento exponencial e estacionárias. Os resultados do teste ABTS, revelaram que todas as estirpes possuem elevadas percentagens de inibição do radical (algumas até 90% de inibição), ou seja, elevada capacidade antioxidante. Com os testes FRAP e Folin-C, apenas a estirpe MICOI_18 revelou ser interessante, pois foram obtidos valores máximos de 6 mmol Trolox/kg peso seco e 1 mg GAE/g peso seco, respetivamente. Contudo, os valores obtidos são inferiores quando comparados com os de outras espécies.Como resultados principais, foram obtidos dados de crescimento em meio solidificado (taxas de crescimento) e líquido (curvas de crescimento) das estirpes regionais de Laetiporus. Uma estirpe de Laetiporus (MICOI_23) revelou-se como potencial candidata a cultivo e os valores obtidos para os testes antioxidantes confirmaram o potencial antioxidante médio da espécie. Para além disso, o facto de estarem conservadas (juntamente com outras espécies de cogumelos com interesse biotecnológico) permite que estas possam ser usadas para investigação futura.<br>Presently, we depend on fungi on a broader sense, because of their role as decomposers, but also in specific matters specially relating to agriculture and medicine. Thus, this work was focused on biotechnological approaches regarding isolation, cultivation and antioxidant potential of fungi, with special emphasis on Laetiporus sulphureus, an edible mushroom with interesting organoleptic properties.Firstly, several regional edible/medicinal fungi (and of some commercial strains), with special emphasis on Laetiporus sulphureus were isolated. This resulted in the composition of a mycological library named Mycological Collection of Coimbra (MICOI), that for now holds 29 fungal isolates, 8 of them of Laetiporus sulphureus. The results supported the conservation method used (submersion in distilled water at room temperature), which proved effective for the maintenance of saprophytic species for at least 5 years, but it is not a fool proof method, especially for mycorrhizal species.Next, strains mycelium growth on PDA medium was assessed, in order to select a strain for cultivation with a high growing rate. Laetiporus sulphureus (MICOI_23) was chosen, but cultivation on different substrates did not allow for fruiting. Although in the cold shock induction treatment, distinct mycelial formations appeared. Laetiporus cultivation seems to be very selective regarding strain and taking into account that there is only one successful case of cultivation, a lot is to be improved.Lastly, the antioxidant activity of Laetiporus strains was evaluated through the ABTS, FRAP and Folin-C assays. Beforehand, mycelium growth on PDB had to be tested, regarding growth kinetics and in order to delineate the lag, log and stationary phases of its growth. Our results showed that for the ABTS assay, all strains hold a significant high percentage of inhibition of the ABTS radical (some up to 90% inhibition), meaning that there is high antioxidant activity. For the FRAP and Folin-C assays, only MICOI_18 revealed to be a potential interesting strain regarding antioxidant activity, which presented values of 6 mmol Trolox/kg DW and 1 mg GAE/g DW, respectively. However, the obtained values were lower when compared with other mushroom species.As main results, data relating the growth of regional Laetiporus strains on solidified (growth rates) and liquid (growth curves) medium was obtained. A strain of Laetiporus (MICOI_23) revealed to be a potential candidate for cultivation and the obtained values for the antioxidant assays confirmed the species average antioxidant activity. Besides, the fact that the isolates were conserved (along with other biotechnological interesting mushroom species) allows for them to be used in future research.

碩士<br>國立聯合大學<br>化學工程學系碩士班<br>105<br>This study used mushroom cultivation waste as a material to prepare different characteristics activated carbon through three activation methods, where the physical and chemical properties and other application characteristics were investigated. There were seven adsorbents, including activated carbon obtained from a series of different ratios of KOH (K2, K3, K3.5, K4), from the steam activation method, with a fixed activation temperature under different activation temperatures (S850, S900), and from 35 wt% H3PO4 (PA). The specific surface area of the activated carbon in this study were between 572 and 2064 m2/g, with K4 achieving the best area. A kinetic adsorption experiment was conducted, where ten absorbates were employed to absorb dyes (MB, MG, AB74), phenols (Phenol, p-Cresol, 4-BP, 4-CP, 2,4-DCP) and emerging polluntants (CF, CZ). The adsorption kinetics was simulated and analyzed through a intraparticle diffusion (IPD) model, the Elovich Model, the pseudo-first order (PFO) kinetic model, and the pseudo-second order (PSO) kinetic model. The results showed that the KOH-derived activated carbon achieved better fitting for dye adsorption using the IPD Model; the Elovich Model obtained better fitting for phenols adsorption; that the steam and H3PO4-based activated carbon gave better fitting for dye and phenols adsorption using the IPD Model. The K4 activated carbon had the best performance for dye adsorption, and the adsorption of phenols was the best for S900. At 1 atm and 273K, the K4 have the largest carbon dixoide adsorption capacity, reaching 14.9 mol/g. An electrochemical test conducted usig cyclic voltammetry at a scan speed of 20 mV/s suggested that the optimum capacitance value achieved by K3.5 could reach 178 F/g in 0.5M H2SO4 electrolyte.

Full textAbstract:
碩士<br>國立屏東科技大學<br>植物保護系所<br>96<br>King oyster mushroom belongs to Pleurotaceae of Agaricales. In present, the major culture substrate for cultivating king oyster mushroom is hardwood sawdust in Taiwan. But hardwood sawdust is getting as a short resource. Therefore, the purpose in this research is to find the substitutive culture substrates for king oyster mushroom and to study the recycle of used bag-log composts due to decreasing the demand of hardwood sawdust, and the nutrition amendment to increase the mushroom yield. Culture materials experiment is conducted with guinea grass, pangolagrass, carpetgrass, rice straw, hardwood sawdust and pine sawdust that are fermentated to be as composts. 47.5% of biological efficiency (BE) obtained is the highest with pine sawdust and cow manure compost. The 30.2% is secondary in pine sawdust compost. Comparing the fermentated and nonfermentated culture substrates, the mycelial growth is great in 9.0 cm of diameter in nonfermentated pangolagrass for 14 days. In experiment of mixing nonfermatated pine sawdust with other culture substrates compost, the best production, 39.8% of BE, for king oyster mushroom, is the mixture with pangolagrass compost. In experiment of amending coconut shell fiber in nonfermatated pine sawdust culture substrates, it all increase mycelia growth with35%, 25% and 15% supplement. It is no notable good efficiency for mycelia growth with supplement cotton seed hull in nonfermatated pine sawdust culture substrates. But it can increase the average weight of fruiting body with supplement 15% cotton seed hull. The 42.9% of biological efficiency obtained from supplement 15% cotton seed hull in pangolagrass compost is significantly different from that of non cotton seed hull supplement. In nutrition supplement experiment, it is no notable difference for mycelia growth among all treatments in mixture of 8% rice bran with supplement 2% yeast flour, soy bean flour, corn flour and molasses in nonfermentated pine sawdust respectively. Whereas it is good for mycelial growth to mixed 2% corn flour, yeast powder with 8% rice bran in pangolagrass compost. The best biological efficiency of 55.4%, is gotten in mixing 2% soy bean flour with 8% rice bran to pine sawdust for mushroom yield experiment. In different nutrition proportion supplement of nonfermentated pine sawdust, it is better for mycelia growth and biological efficiency in mixture 10% corn starch, soy bean flour with 10% rice bran ,respectively, than that of nonsupplement.62.0% and 63.5% of biological efficiency are obtained respectively from the miture of 10% corn starch and 10%rice bran amended into nonfermanted pine sawdust and pangolagrass compost. In the experiment of rice bran amendment, it is high biological efficiency of 76.2% and 73.5% in nonfermatated pine sawdust to supplement 30% and 40% rice bran, while 34.3%, in supplement 10% rice bran. In the ultilization of used pine sawdust compost, 59.7% of biological efficiency of used compost, is significant difference from 43.4% of new compost. In spraying nutrition liquid onto nonfermatated pine sawdust substrates, Czapek’ liquid sprayed one week after first harvesting hash can increase the biological efficiency and mushroom yield. In test of the surface cutting of mycelia on nonfermentated pine sawdust, the 0.5 cm thickness cutting is better than noncutling for mushroom production and gets 47.7% of biological efficiency.

Full textAbstract:
碩士<br>國立中興大學<br>園藝學系所<br>104<br>With an attempt to select heat tolerant strains of king oyster mushroom at mycelium growth stage and to evaluate the feasibility of king oyster mushroom cultivation at high temperatures, ten king oyster mushroom strains collected from different farms were screened under high temperature. Mycelium extension rate (MER) increased in all ten king oyster mushroom strains when grown in potato dextrose agar (PDA) at 27℃ or 30℃, however, a decrease of MER was generally noticed when grown in PDA 33℃. Our results indicated that strains 3, 4 are more heat tolerant for the decrease in MER at 33℃ was less profound in these two strains. In contrast, 7,9 are considered as heat sensitive strains.
Heat tolerant and heat sensitive strains obtained in this study were cultivated in PE bag at 33℃. After 42 days, mycelium length showed significant difference between heat tolerant and heat sensitive strains and it took about 60 and 80 days for the mycelium to completely colonize the substrate, respectively. Comparing to the control (25℃), all stains spent longer time to finish mycelium growth stage at 33℃. In addition, the mycelium color, density and contamination rate of heat sensitive strains were poorer than heat tolerant strains. Pleurous eryngii mycelium growth at 33 or 25℃ and fruiting body development at 15℃ didn’t result in any difference in days of primordia appearance and the harvest time of fruiting body, but lower yield and decreased biological efficiency were observed. After different strains of king oyster mushroom were subjected to 33 or 25℃ for mycelium growth and 15℃ for fruiting body development, nutrient analysis of fruiting body indicated that the difference in macronutrients between stipe and pileus was less than that in micronutrients, the absorption of macronutrients in heat tolerant strain 3 was not affected when mycelium was growing at high temperature, total phenolic compound was not decreased in the stipe but was decreased in the pileus of some strains tested when mycelium was growing at high temperature, a similar trend was also observed for the soluble proteins with the largest decrease in the pileus of heat tolerant stain 3.
When heat tolerant strain 3 was subjected to 33 or 25℃ for mycelium growth and 20℃ for fruiting body development, days of primordia appearance was not affected but the fruiting body development was hindered and the was hindered and the yield and shape of fruiting body was less satisfactory due to insufficient of low temperature. Interestingly, some nutrient contents, total phenolic compound and soluble proteins were increased in the fruiting body when cultivated under similar conditions. Overall, our results suggested the potential of heat tolerant stain 3 to be cultivated under high temperature conditions.

Full textAbstract:
碩士<br>國立中興大學<br>機械工程學系所<br>104<br>In this study, mushroom cultivation waste (MCW) was used as the feedstock for bio-oil production from fast Pyrolysis using a 30 kWth fluidized bed. The pyrolysis temperature was in 400~ 600°C range. N2 was used as the carrier gas and its flow rate was chosen as 2~4 times of ultra minimum fluidization flow rate (Umf). The sample feed rate was varied from 2 to 3 kg/hr. The experimental results showed that maximum bio-oil production of 27.5% can be obtained under the conditions of 400°C, 2 Umf, and 2 kg/hr, for temperature, carrier gas flow rate, and sample feed rate, respectively. The measured pH value of the resulted bio-oil was 4.42. The GC-MS analysis indicated that the major species in the bio-oil are 2-furylmethanol, acetamide, butyrolactone, corylone, phenol, and 2-methoxy- and syringol.
In addition to original MCW sample, the torrefied MCW sample with temperatures of 250°C, 300°C, and 350°C, were also used as the feedstock for bio-oil production from pyrolysis in this study. For temperature, carrier gas flow rate, and feed rate of 400°C, 2 Umf, and 2 kg/hr, the pyrolysis results using torrefied samples indicated the bio-oil production decreased. However, the pH value increased, indicating that some part of organic acid was removed due to the torrefaction pretreatment. From TGA analysis, it was shown that the pyrolytic activation energy can be reduced by using torrefied sample.
The thermodynamic equilibrium analysis based on minimization of system Gibbs function for the MCW pyrolysis was also carried out in this study. The RGibbs reactor provided in ASPEN Plus was employed for evaluating the equilibrium pyrolytic products. The results indicated that both pyrolytic char and bio-oil productions decreased with the increase in temperature while pyrolytic syngas production increased with the increased temperature.
