Abstract:
Liquid-state fermentation (LSF) and solid-state fermentation (SSF) are two forms of industrial production of lactic acid bacteria (LAB). The choice of two fermentations for LAB production has drawn wide concern. In this study, the tolerance of bacteria produced by the two fermentation methods to acid stress was compared, and the reasons for the tolerance differences were analyzed at the physiological and transcriptional levels. The survival rate of the bacterial agent obtained from solid-state fermentation was significantly higher than that of bacteria obtained from liquid-state fermentation after spray drying and cold air drying. However, the tolerance of bacterial cells obtained from liquid-state fermentation to acid stress was significantly higher than that from solid-state fermentation. The analysis at physiological level indicated that under acid stress, cells from liquid-state fermentation displayed a more solid and complete membrane structure, higher cell membrane saturated fatty acid, more stable intracellular pH, and more stable activity of ATPase and glutathione reductase, compared with cells from solid-state fermentation, and these physiological differences led to better tolerance to acid stress. In addition, transcriptomic analysis showed that in the cells cultured from liquid-state fermentation, the genes related to glycolysis, inositol phosphate metabolism, and carbohydrate transport were down-regulated, whereas the genes related to fatty acid synthesis and glutamate metabolism were upregulated, compared with those in cells from solid-state fermentation. In addition, some genes related to acid stress response such as cspA, rimP, rbfA, mazF, and nagB were up-regulated. These findings provide a new perspective for the study of acid stress tolerance of L. paracasei Zhang and offer a reference for the selection of fermentation methods of LAB production.

Abstract:
Effects of solid versus semi-solid fermentations on the chemical and organoleptic qualities of finger millet Jand were studied. Millet was fermented under solid and semi-solid states by using defined fermentation starter and the Jand was subjected to chemical and sensory analyses. Results indicated that except on moisture and alcohol contents, semi-solid fermentation reflected a significant effect (p<0.05) on the chemical characteristics of millet Jand. TSS, acidity and ester contents increased substantially in semi-solid fermentation as compared to solid-state one. Millet fermented with 50% water addition had more than 2-folds higher total acidity than that of solid-state fermented and every 50% increase in water addition nearly doubled the fixed acidity of the products. No remarkable improvement on the chemical and sensory quality of millet Jand was found by using semi-solid state fermentation. J. Food Sci. Technol.

Abstract:
The property differences between bacteria produced from solid-state and liquid-state fermentations have always been the focus of attention. This study analyzed the stress tolerance and transcriptomic differences of the probiotic Lacticaseibacillus casei Zhang produced from solid-state and liquid-state fermentations under no direct stress. The total biomass of L. casei Zhang generated from liquid-state fermentation with MRS medium (LSF-MRS) was 2.24 times as much as that from solid-state fermentation with soybean meal-wheat bran (SSF-SW) medium. Interestingly, NaCl, H2O2, and ethanol stress tolerances and the survival rate after L. casei Zhang agent preparation from SSF-SW fermentation were significantly higher than those from LSF-MRS fermentation. The global transcriptomic analysis revealed that in L. casei Zhang produced from SSF-SW fermentation, carbohydrate transport, gluconeogenesis, inositol phosphate metabolism were promoted, that pentose phosphate pathway was up-regulated to produce more NADPH, that citrate transport and fermentation was extremely significantly promoted to produce pyruvate and ATP, and that pyruvate metabolism was widely up-regulated to form lactate, acetate, ethanol, and succinate from pyruvate and acetyl-CoA, whereas glycolysis was suppressed, and fatty acid biosynthesis was suppressed. Moreover, in response to adverse stresses, some genes encoding aquaporins (GlpF), superoxide dismutase (SOD), nitroreductase, iron homeostasis-related proteins, trehalose operon repressor TreR, alcohol dehydrogenase (ADH), and TetR/AcrR family transcriptional regulators were up-regulated in L. casei Zhang produced from SSF-SW fermentation. Our findings provide novel insight into the differences in growth performance, carbon and lipid metabolisms, and stress tolerance between L. casei Zhang from solid-state and liquid-state fermentations.

Abstract:
Biotransformation of landfill solid wastes is a slow process requiring decades for completion. Accelerated anaerobic fermentation in modulated landfill environments may alleviate or eliminate pollution of land, water and air. This research was undertaken to demonstrate the application of biphasic fermentation to a simulated laboratory-scale landfill to effect rapid biomethanation of biodegradable solids. The biphasic process consisted of solid-state, acidogenic fermentation of the organic fraction of MSW followed by biomethanation of acidic hydrolysates in a separate methane fermenter. Solid-state fermentation of the MSW with effluent recirculation resulted in rapid hydrolysis, acidification and denitrification, with soluble COD and VFA concentrations accumulating to inhibitory levels of 60,000 mg/l and 13,000 mg/l, respectively, at a pH of 4.5. The landfill gas methane concentration reached a maximum of 55 mol.%. By comparison, the methanogenic reactor produced high methane-content (70–85 mol.%) gases. The biphasic process effected carbohydrate, lipid, and protein conversion efficiencies of 90%, 49%, and 37%, respectively. Development of a Monod-type product-formation model was undertaken to predict methane formation and to determine kinetic parameters for the methanogenic processes in the simulated landfill and separate methane reactors. A first-order solids hydrolysis rate constant of 0.017 day−1 was evaluated to show that landfill solids hydrolysis was slower than the inhibited methanogenesis rate.

Abstract:
The amylase producing fungi were isolated from spoiled fruits, vegetables and soil, in and around Bangalore, Karnataka, India. The isolates were identified and five fungal species were screened. The best amylase producer among them, Aspergillus sp was selected for enzyme production by both sub merged fermentation using mineral salt medium (MSM) and solid state fermentations using wheat bran as a solid substrate. The various parameters influencing solid state fermentation were optimized. The most important factors are such as pH, incubation temperature, incubation period, carbon sources, nitrogen sources and moisture content. The maximum amount of enzyme production was obtained when solid state fermentation was carried out with soluble starch as carbon source and beef extract (1% each) as nitrogen source, optimum conditions of pH 7.0, an incubation temperature of 25 (±2) °C, incubation time 96 h and 62% moisture content.

Abstract:
Solid state fermentation (SSF) refers to the microbial fermentation, which takes place in the absence or near absence of free water, thus being close to the natural environment to which the selected microorganisms, especially fungi, are naturally adapted. The current status of SSF research globally was discussed in terms of articles publication. This was followed by discussion of the advantages of SSF and the reason for interest in SSF as a notable bioprocessing technology to be investigated and compared to submerged fermentation (SmF) for the production of various added-value products. SSF also proved to be a potential technology to treat solid waste produced from food and agricultural industry and to provide environmental benefits with solid waste treatment. A summary was made of the attempts at using modern SSF technology for future biorefineries for the production of chemicals. Many works were carried out in the Satake Centre for Grain Process Engineering (SCGPE), University of Manchester, to prove the strategy of using SSF for the production of hydrolysate rich in nutrients for sequel microbial fermentation with or without adding any commercial nutrients. The research findings presented in this thesis are based on a series of SSF experiments carried out on systems varying in complexity from simple petri dishes to our own design of bioreactor systems. They were conducted to assess a solution for biomass estimation, enzymes production, and successful mass and heat transfer. A proper technique for inoculum transfer prior to the start of the fermentation process was developed. In SSF, estimation of biomass presents difficulties as generally the fungal mycelium penetrates deep and remains attached with the solid substrate particles. Although many promising methods are available, the evaluation of microbial growth in SSF may sometimes become laborious, impractical and inaccurate. Essentially, this remains another critical issue for monitoring growth. In these studies, measurement of colour changes during SSF are presented as one of the potential techniques that can be used to describe growth, complementary to monitoring metabolic activity measurement, such as CER, OUR and heat evolution, which is directly related to growth. For the growth of Aspergillus awamori and Aspergillus oryzae on wheat bran, soybean hulls and rapeseed meal, it was confirmed that colour production was directly proportional to fungal growth. This colourimetric technique was also proved to be a feasible approach for fungal biomass estimation in SmF. This new approach is an important complementation to the existing techniques especially for basic studies. The key finding is that the colourimetric technique demonstrated and provided information of higher quality than that obtained by visual observation or spores counting. The effect of aeration arrangements on moisture content, oxygen (O2), mass and heat transfer during SSF was investigated. A. awamori and A. oryzae were cultivated on wheat bran in newly designed four tray solid state bioreactor (SSB) systems. The new tray SSB systems were: (1) single circular tray SSB, (2) multi-stacked circular tray SSB, (3) Single rectangular tray SSB and (4) multi-square tray SSB. The purpose was to study the effect, on heat and water transfer, of operating variables, fermentation on the perforated base tray and internal moist air circulation under natural and forced aeration. Temperature, O2 and carbon dioxide were measured continuously on-line. Enzyme activity, moisture content and biomass were also measured. The results suggest that the air arrangements examined have a remarkable effect on the quantity of biomass produced using measurement of spores and enzymes production. The strategy presented in these studies allowed quantitative evaluation of the effect of forced internal moist air circulation on the removal of metabolic heat. With the proposed strategy, it was possible to maintain the bed temperatures at the optimum level for growth. However, the effect on moisture content was very different for the two fungi. It was found that the ability of A. oryzae to retain moisture was much higher than that of A. awamori. This is possibly due to the higher levels of chitin in A. oryzae. Greater spores and enzymes (glucoamylase, xylanase and cellulase) production was observed for A. awamori in multi-stacked circular tray and multi-square tray SSB systems compared to the conventional petri dishes and the other two systems. A. oryzae was excellent in producing protease in the same bioreactors. A direct technique of establishing a correlation between fungal growth and CER, OUR, heat evolved was proven successful in this work. The information obtained from CER and OUR led to the estimation of respiratory quotient (RQ). RQ describes the state of the fungal population in the tray SSB and gives an indication of fungal metabolic behaviour. RQ values < 1 were obtained from 38 experiments using four tray SSB systems for the two fungi. A kinetic model based on CO2 evolution instead of biomass concentration was examined in order to simplify the required experiments for kinetic model development. A Gompertz model was used to fit the integrated CO2 data and predict the quantity of CO2 evolution in all experiments. A correlation was found between the heat evolution and CER. The performances of tray SSB systems can be improved by constructing them as multi-trays. The multi-tray systems improved the mass transfer considerably compared with single tray systems. In addition, the multi-tray systems allowed precise measurement of the gradients of CO2, enzymes, spores and fungal biomass. In addition, the air arrangements using moistened air were successful in maintaining moisture content, adequate O2 supply and control of temperature, and hence, increased the productivity of both fungi. Overall A. awamori and A. oryzae have their own ability and performance to degrade and utilise the complex compositions contained in the solid substrate and fermentation conditions may lead to possible comparisons. In addition, multi-stacked circular tray and multi-square tray SSB systems demonstrated an excellent system for further investigations of mass transfer and possibly for large scale operation, though considerable optimisation work remains to be done, for example the height/diameter ratio and total number of trays should be optimised.

Abstract:
Vitamins are required by organisms as vital nutrients in limited amounts as they cannot be synthesized in vivo. Many vitamins and related compounds are now industrially produced, and are widely used as food or feed additives, medical or therapeutic agents, complementary health products or cosmetics. The consumption of a particular form of vitamin K, namely Menaquinone 7 (MK7), as part of the diet shows a correlation with reduced risk of bone fractures and of some cardiovascular disorders. The concentration of MK7 in food products is low and, hence, there may be a benefit for supplementary MK7. MK7 production in Solid state fermentation (SSF) has received only limited attention in the open literature, in spite of natto production being hundreds of years old. The aim of this thesis is to assess the feasibility of enhancing the concentration of MK7 from SSF for the large scale production of a MK7 rich fermented food supplement. This process eliminates the expensive organic solvent extraction used to purify MK7, which is unlikely to be economical for animal vitamin production. Static and dynamic SSF for MK7 production were scaled up after initial screening studies. A novel, custom made concentric Rotating Drum Bioreactor (RDB) (3 kg) and packed bed fermenter (4 kg) were designed in house and fabricated for large scale studies. By using the scaled up RDB and packed bed reactor, MK7 production was scaled up from 10 g in bench scale to 4 kg. Mathematical models derived for the prediction of process variables will be important tools in the design and optimization of performance of large scale SSF bioreactors. This study contributed appreciably to the understanding of the operation of RDBs and packed bed for MK7 production in SSF which are critical for further development of industrial level MK7 production.

Abstract:
Dependence on foreign oil remains a serious issue for the U.S. economy. Additionally, automobile emissions related to petroleum-based, fossil fuel has been cited as one source of environmental problems, such as global warming and reduced air quality. Using agricultural and forest biomass as a source for the biofuel ethanol industry, provides a partial solution by displacing some fossil fuels. However, the use of high cost enzymes as an input is a significant limitation for ethanol production.Economic analyses of cellulase enzyme production costs using solid state cultivation (SSC) are performed and compared to the traditional submerged fermentation (SmF) method. Results from this study indicate that the unit costs for the cellulase enzyme production are $15.67 per kilogram ($/kg) and $40.36/kg, for the SSC and SmF methods, respectively, while the market price for the cellulase enzyme is $36.00/kg. Profitability analysis and sensitivity analysis also provide positive results.Since these results indicate that the SSC method is economical, ethanol production costs may be reduced, with the potential to make ethanol a viable supplemental fuel source in light of current political, economic and environmental issues.

Abstract:
En aquest treball es proposa una tecnologia alternativa per a la producció de soforolípids (SLs), un tipus de biosurfactant, presentats com a alternativa als surfactants produïts químicament degut a la seva major eficiència i millor perfil mediambiental. En aquest treball s'han dut a terme dues estratègies per a millorar la relació de cost-eficiència dels SLs respecte als surfactants produïts químicament, que és el que determina la seva viabilitat econòmica. Ambdues estratègies estan basades en la producció de SLs mitjançant la fermentació en estat sòlid. La primera estratègia va consistir en el ús d’un residu de winterització (RW) amb l'objectiu de disminuir el preu dels substrats i, per tant, el cost final de producció dels SLs. Es va utilitzar melassa de sucre com a co-substrat i palla de blat com a suport inert. El procés va ser optimitzat en base al rati de substrats, la velocitat d’aeració i a la mida de l’inòcul a escala de 100-g, obtenint-se un rendiment de 0.261 g per g de substrat al dia 10. El procés optimitzat, va ser escalat satisfactòriament a un bioreactor de llit fix de 40-L, però posteriorment, es van observar problemes associats amb l'eliminació de calor durant l'escalat a un bioreactor de 100-L amb barreja intermitent. L'estructura química i les propietats interfacials de la barreja natural del SLs produït a partir del RW es va estudiar durant una estança al Rensselaer Polytechnic Institute (NY, USA). La segona estratègia consistí en l'ús de àcid esteàric (C18:0) per a l'obtenció de SLs amb una estructura específica que millori les propietats fisicoquímiques de la barreja natural de SLs i, per tant, la seva eficiència. Es va utilitzar melassa de sucre com a co-substrat i escuma de poliuretà com a suport inert. L'efecte de la densitat de l'escuma de poliuretà i la capacitat de retenció hídrica van ser avaluades i el procés va ser optimitzat en base al rati de substrats e inòcul, obtenint-se un rendiment final de 0.211 g de SLs per g de substrat. Els SLs produïts contenien elevades quantitats de SLs C18:0. Es van observar correlacions significatives entre el rendiment de SLs i l’oxigen consumit (COA). Això suggereix que el COA pot ser utilitzat com a mesura indirecta de la producció de SLs per a la monitorització en línea de processos de FES. Aquesta tesi representa el començament d'una nova línia d'investigació centrada en la producció de SLs per FES en el Grup de Investigació en Compostatge (GICOM) del Departament d’Enginyeria Química, Biològica i Ambiental de la Universitat Autònoma de Barcelona.

Se evaluó el efecto de la densidad de la espuma de poliuretano y la capacidad de retención hídrica y el proceso fue optimizado en base a la ratio de sustratos e inóculo obteniendo un rendimiento final de 0.211 g de SLs por g de sustrato. Los SLs producidos presentaron contenidos elevados de SLs diacetilados C18:0 acídico y lactónico. Se observaron correlaciones significativas entre el rendimiento de SLs y el oxígeno consumido (COA).

This work proposes a potential alternative approach to produce sophorolipids (SLs), a type of biosurfactant, which are presented as an alternative to chemically-produced surfactants due to their higher efficiency and better environmental compatibility. Two strategies have been performed in this work to increase their cost-performance relative to petroleum based surfactants, which determines their commercial viability. Both are based in the production of SLs by the solid-state fermentation (SSF) of solid hydrophobic substrates by the yeast Starmerella bombicola. The first strategy was to use winterization oil cake (WOC), an oil cake that comes from the oil refining industry, to decrease the price of the substrates and, therefore, the final production costs of SLs. Sugar-beet molasses was used as co-substrate and wheat straw was chosen as inert support. The process was optimized in terms of substrates ratio, aeration rate and inoculum size at 0.5-L scale to obtain a yield of 0.261 g of SLs per g of substrate at day 10. The optimized process was successfully scale-up to a 40-L packed-bed bioreactor but problems associated with heat removal were found during the scale-up to a 100-L intermittently-mixed bioreactor. The chemical structure and interfacial properties of the SL natural mixture produced from the WOC were studied during a research stay at the Rensselaer Polytechnic Institute (RPI) in NY, USA. The second strategy consisted in the use of stearic acid (C18:0) to obtain SLs with a specific structure that improves the physicochemical properties of the SL natural mixture and, therefore, their performance. Sugar-beet molasses was used as co-substrate and polyurethane foam (PUF) functioned as inert support. The effect of PUF density and water holding capacity was assessed and the process was optimized in terms of substrate and inoculum ratio to obtain a final yield of 0.211 g of SLs per g of substrate. SLs produced herein had high contents of diacetylated acidic and lactonic C18:0 SLs. There were significant correlations between the SL yield and the oxygen consumed (COC). This suggests that the respiration parameter COC, can be used as an indirect measurement of the production of SLs for the on-line monitoring of SSF processes. This thesis represents the beginning of a new research line focused on the production of SLs by SSF in the Composting Research Group (GICOM) at the Department of Chemical, Biological and Environmental Engineering of the Universitat Autònoma de Barcelona.

Abstract:
Solid state fermentation of canola meal has been carried out for the reduction of its phytic acid content. Several microorganisms were surveyed for this purpose. The phytic acid content of canola meal was reduced by 26%, 60% and 66% using Saccharomyces cerevisiae, Rhizopus oligosporus NRRL 2990 and Aspergillus niger NRC 401121 respectively after 120 hours of fermentation. Aspergillus ficuum NRRL 3135 was found to be the best for the reduction of phytic acid content. For this reason, this microorganism was studied more extensively. In the study of the phytase (EC 3.1.3.8) from Aspergillus ficuum NRRL 3135, it was found that the production of the enzyme in a submerged batch process was inhibited by high concentrations of glucose. The inhibition was overcome by applying a fed batch technique in the production of the enzyme. Tests carried out at different oxygen concentrations revealed that aeration had a beneficial effect on the production of the enzyme. (Abstract shortened by UMI.)

Abstract:
Justification: Canola meal (CM) is a protein rich co-product of canola oil extraction process, and its use is restricted to animal diet due to the presence of high fibers and antinutritional factors (ANFs) such as glucosinolates and phytic acids. As attempts to provide canola meal with low ANFs and fibers, traditional sprouting process of canola seed followed by sprout defatting and mild washing water pretreatment of hexane extracted CM were applied. The obtained canola sprout meal (CSM) and washed hexane extracted canola meal (WHECM) along with raw hexane extracted canola meal (HECM) underwent submerged and solid-state fermentation. It was noticed that used fungi yielded different outcomes in terms of fiber and ANFs reduction. The objective of this this study was to evaluate the activities of enzymes (cellulase, endoglucanase, and β-glucosidase) produced by three fungal strains (Aureobasidium pullulans, Neurospora crassa and Trichoderma reesei) cultivated on three differently processed canola substrates (CSM, WHECM and HECM) during solid- and submerged- state fermentations using mono and coculture inoculation. Our results showed that cellulase, β-glucosidase and endoglucanase activity significantly varied based on substrate used, mode of fermentation (solid/submerged) and inoculation type (mono/co) even under same strain, highlighting the effect of pre-processed meals, and fermentation conditions on the overall fungal enzymatic activities and their impact on the nutritional composition of the substrate/products.

Abstract:
The drying process is an important step during the production process of biopesticides. Nonetheless, this process causes a stress condition associated to loss of water; resulting a decrease of enzymatic activity, viability, and virulence in case of entomopathogenic fungi. Thus, suitable conditions must be implemented through the entire process to improve desiccation tolerance and keep stable cells. Therefore, the aim of this work was to evaluate several medium compositions in solid-state fermentation (T1, T2, T3, T4, and T5), and determine the e ect on viability, induction of enzymatic activity, and virulence of dried conidia.

Abstract:
The overall objectives of the project were: (a) To measure and study in situ the effect of irrigation with reclaimed sewage effluents on redox processes and related chemical dynamics in soil profiles of agricultural fields. (b) To study under controlled conditions the kinetics and equilibrium states of selected processes that affect redox conditions in field soils or that are effected by them. Specifically, these include the effects on heavy metals sorption and desorption, and the effect on pesticide degradation. On the basis of the initial results from the field study, increased effort was devoted to clarifying and quantifying the effects of plants and water regime on the soil's redox potential while the study of heavy metals sorption was limited. The use of reclaimed sewage effluents as agricultural irrigation water is increasing at a significant rate. The relatively high levels of suspended and, especially, dissolved organic matter and nitrogen in effluents may affect the redox regime in field soils irrigated with them. In turn, the changes in redox regime may affect, among other parameters, the organic matter and nitrogen dynamics of the root zone and trace organic decomposition processes. Detailed data of the redox potential regime in field plots is lacking, and the detailed mechanisms of its control are obscure and not quantified. The study established the feasibility of long-term, non-disturbing monitoring of redox potential regime in field soils. This may enable to manage soil redox under conditions of continued inputs of wastewater. The importance of controlling the degree of wastewater treatment, particularly of adding ultrafiltration steps and/or tertiary treatment, may be assessed based on these and similar results. Low redox potential was measured in a field site (Site A, KibutzGivat Brenner), that has been irrigated with effluents for 30 years and was used for 15 years for continuous commercial sod production. A permanently reduced horizon (Time weighted averaged pe= 0.33±3.0) was found in this site at the 15 cm depth throughout the measurement period of 10 months. A drastic cultivation intervention, involving prolonged drying and deep plowing operations may be required to reclaim such soils. Site B, characterized by a loamy texture, irrigated with tap water for about 20 years was oxidized (Time weighted average pe=8.1±1.0) throughout the measurement period. Iron in the solid phases of the Givat Brenner soils is chemically-reduced by irrigation. Reduced Fe in these soils causes a change in reactivity toward the pesticide oxamyl, which has been determined to be both cytotoxic and genotoxic to mammalian cells. Reaction of oxamyl with reduced-Fe clay minerals dramatically decreases its cytotoxicity and genotoxicity to mammalian cells. Some other pesticides are affected in the same manner, whereas others are affected in the opposite direction (become more cyto- and genotoxic). Iron-reducing bacteria (FeRB) are abundant in the Givat Brenner soils. FeRB are capable of coupling the oxidation of small molecular weight carbon compounds (fermentation products) to the respiration of iron under anoxic conditions, such as those that occur under flooded soil conditions. FeRB from these soils utilize a variety of Fe forms, including Fe-containing clay minerals, as the sole electron acceptor. Daily cycles of the soil redox potential were discovered and documented in controlled-conditions lysimeter experiments. In the oxic range (pe=12-8) soil redox potential cycling is attributed to the effect of the daily temperature cycle on the equilibrium constant of the oxygenation reaction of H⁺ to form H₂O, and is observed under both effluent and freshwater irrigation. The presence of plants affects considerably the redox potential regime of soils. Redox potential cycling coupled to the irrigation cycles is observed when the soil becomes anoxic and the redox potential is controlled by the Fe(III)/Fe(II) redox couple. This is particularly seen when plants are grown. Re-oxidation of the soil after soil drying at the end of an irrigation cycle is affected to some degree by the water quality. Surprisingly, the results suggest that under certain conditions recovery is less pronounced in the freshwater irrigated soils.
