"Higher Ant Diversity in Native Vegetation Than in Stands of the Invasive Arundo, Arundo donax L., Along the Rio Grande Basin in Texas, USA".

Abstract (sommario):

Our hypothesis was that there will be greater ant biodiversity in heterogeneous native vegetation compared with Arundo stands. Changes in ant biodiversity due to Arundo invasion may be one of the ecological changes in the landscape that facilitates the invasion of cattle fever ticks from Mexico where they are endemic. Ants collected in pitfall traps were identified and compared between native vegetation and stands of Arundo, Arundo donax L., monthly for a year at 10 locations. A total of 82 752 ants representing 28 genera and 76 species were collected. More ants were collected in the native vegetation which also had greater species richness and biological diversity than ants collected from Arundo stands. It is suggested that the greater heterogeneous nature of native vegetation provided greater and more predictable nourishment in the form of nectars and more abundant arthropod prey when compared with Arundo stands.

Abstract (sommario):

Filter systems have the ability to remove pollutants from wastewater. However, to increase the treatment efficiency, the filter made of plants has been recommended which has been called the biofilter. The objective of this study was to examine the performance of biofilter made by Arundo donax L. on domestic wastewater treatment. In this paper, a laboratory study using vertical flow constructed wetlands planted with Arundo donax L. and without any other plants were conducted. For the biofilter planted in Arundo donax L., the removal of TN, NH4+-N and TP 89%, 93% and 98% respectively. In particular, we also got the nitrogen and phosphorus content of different parts of Arundo donax L. which was divided into root, stem and leaves. For the total nitrogen content in the plant, there is a quantitive relationship of stem<root<leaves. For the total phosphorus content, the relationship is root<stem<leaves quantitatively. Whilst, compared with the total removal of nitrogen and phosphorus, the removal via plant absorption accounts for 22% and 29% separately. The results of this research suggest that Arundo donax L. with large leaves could be used as a main plant in the domestic wastewater biofilter.

Abstract (sommario):

Genetic diversity and cytogenetics of 31 accessions of Arundo L., collected from North America and South Asia, were characterized using 20 intersimple sequence repeat (ISSR) markers, flow cytometry, and cytology. In addition, field trials of 23 Arundo donax L. accessions were established in 2011 and harvested in 2012 to 2013 to assess annual biomass yields. Cluster analysis, based on Jaccard’s similarity coefficient method, clearly differentiated Arundo formasana Hack. from A. donax and a third unidentified Arundo taxon. Arundo donax further contained two subgroups representing North American (naturalized and cultivated) and South Asian collections. Within each A. donax subgroup, genetic distances were very low (0.03 for North America and 0.07 for South Asia). Principle coordinate analysis further supported distinct clusters. Relative genome sizes were determined using Pisum sativum L. as the reference genome and 6-diamidino-2-phenylindole (DAPI) fluorochrome. Chromosome numbers (2n), ploidy levels, and 2C relative genome sizes ranged from ≈62 to 105, near 12x to near 18x, and 2.78 to 4.13 pg, respectively, and were similar within each taxa/subgroup. While there was a low level of genetic variability among A. donax accession, dry biomass yields varied significantly ranging from 6.5 to 65 Mg·ha−1 per year for the third growing season.

Abstract (sommario):

The study on the species selection of constructed wetland plants and the purification effects of the constructed wetland plants is the key to ecological wastewater treatment technology. The purification effects of different residence time of wastewater, different constructed wetland plants and their synergistic effect are studied in TP disposal in living wastewater. The results show that the best plant combination in purifying TP is that of Arundo donax, Typha orientalis and Canna generalis, followed by that of Phragmites communis, Arundo donax and Canna generalis. The best plant species in purifying TP is Canna generalis, followed by Arundo donax.

Abstract (sommario):

Polyploidization is a frequent phenomenon in plants, which entails the increase from one generation to the next by multiples of the haploid number of chromosomes. While tetraploidization is arguably the most common and stable outcome of polyploidization, over evolutionary time triploids often constitute only a transient phase, or a “triploid bridge”, between diploid and tetraploid levels. In this study, we reconstructed in a robust phylogenomic and statistical framework the evolutionary history of polyploidization in Arundo, a small genus from the Poaceae family with promising biomass, bioenergy and phytoremediation species. Through the obtainment of 10 novel leaf transcriptomes for Arundo and outgroup species, our results prove that recurrent demiduplication has likely been a major driver of evolution in this species-poor genus. Molecular dating further demonstrates that the species originating by demiduplication stalled in the “triploid bridge” for evolutionary times in the order of millions of years without undergoing tetratploidization. Nevertheless, we found signatures of molecular evolution highlighting some of the processes that accompanied the genus radiation. Our results clarify the complex nature of Arundo evolution and are valuable for future gene functional validation as well as reverse and comparative genomics efforts in the Arundo genus and other Arundinoideae.

Abstract (sommario):

This paper explores the possibility of producing all-lignocellulosic fiberboards from Arundo donax L. as a source of lignocellulosic fibers with no synthetic binders. This raw material was steam exploded with a thermomechanical aqueous vapor process in a batch reactor. The Arundo donax raw material and its obtained pulp were characterized in terms of chemical composition and the results were compared to other lignocellulosic materials. The chemical composition of steam exploded Arundo fibers showed high cellulose and a moderate lignin content suggesting it was a good raw material for fiberboard production. The all-lignocellulosic fiberboards were produced on laboratory scale; using the steam exploded Arundo donax by means of a wet process. The effects of pressing pressure on physical and mechanical properties were evaluated and the conditions that optimize the responses were found. The analyzed properties were density (d); water absorption (WA); thickness swelling (TS); modulus of elasticity (MOE); modulus of rupture (MOR); and internal bond strength (IB). The tested levels of the pressing pressure range from 0.35 to 15 MPa. The optimum IB; MOE; MOR; WA and TS were 1.28 MPa, 7439 MPa, 40.4 MPa, 17.6% and 13.3%, respectively. The obtained fiberboards were of very good quality and more than satisfy the requirements of the relevant standard specifications.

Abstract (sommario):

Arundo donax (Giant reed Plant) contains high level of cellulose, hemicellulose and lignin. It is used as a second generation method for the production of ethanol from lignocellulosic biomasses. Cellulose molecules comprised an unbranched polymer of 1,000 to 1,000,000 D-glucose linking units coupled with beta-1, 4 glycosidic bonds. Microorganism present in beta 1-4 gluconase breaks down the glucosidic linkage in the Microcrystalline structure of the cellulose to cellobiose molecules (a glucose dimer have a beta-1, 4 bond). The cellobiose is subsequently broken down into glucose molecules by an enzyme called beta-glucosidase. The scope of this work entails hydrolysis conversion of cellulose to glucose and other value added products using enzymatic (Cellulase)

Abstract (sommario):

The invasion of riparian habitats by the exotic plant, Arundo donax L., commonly known as the giant reed is one of the greatest threats to ecosystems in Central and Southern California. There have been several efforts to eradicate this plant with varying control methods. This study evaluated some previously known techniques of controlling the giant reed in addition to some novel methodologies to determine the most effective approach. The study site is a section of the Lower Calaveras River that transects University of the Pacific's campus and is a prime example of the devastation caused by the giant reed. The project site was cut and cleared over a period of eight months and divided into fourteen plots. Seven different techniques including a control were selected and each treatment was randomly applied to two plots. The methods chosen were: "cut, resprout and spray", "cut-stem, spray", "chip and compost", "chip and tarp", "compost" and "compost and tarp". The response variables were the "mean regrowth height", "mean circumference of stalks" and the "number of resprouted stalks". A repeated measures ANOVA was used to analyze the response variables. The "compost and tarp" method had the lowest number of resprouted stalks and was also significantly different from the control treatment. None of the other techniques were significantly different from the control but the "compost" method showed some promise. Based on this study, the "compost and tarp" technique is the most effective treatment. The data collection for this study was limited and future experiments should be conducted on a longer time scale to assess the effectiveness of these methods. Further research should also be conducted to evaluate the effectiveness of various biotic factors on the growth of A. donax, which could enhance the efficacy of methodologies currently used to control this introduced invasive plant.

Abstract (sommario):

A crescente demanda energética traz a necessidade de desenvolvimento de novos combustíveis renováveis, visando à menor emissão de partículas e poluentes ao meio ambiente e a substituição dos derivados de petróleo. Atualmente, pesquisas com a utilização de biomassa lignocelulósica vêm sendo desenvolvidas com o objetivo de tornar o processo de produção de etanol de segunda geração economicamente viável. O arundo (Arundo donax L.) é uma gramínea de crescimento rápido, alto rendimento de biomassa e pode ser cultivada em áreas marginais, que em função de características de cultivo, crescimento e produtividade apresenta potencial para produção de etanol de segunda geração. O presente trabalho teve como objetivo estabelecer as melhores condições de pré-tratamento, hidrólise e fermentação da biomassa de Arundo donax L. visando à produção de etanol. Três pré-tratamentos foram testados: pré-tratamento ácido, pré-tratamento ácido seguido de pré-tratamento alcalino e pré-tratamento alcalino. Foram avaliadas variáveis de cada pré-tratamento utilizando planejamento composto central rotacional através da metodologia de superfície de resposta Após a otimização das condições de pré-tratamento, foram avaliadas as variáveis carga enzimática e relação sólido:líquido nos rendimentos de glicose e xilose na hidrólise enzimática. Por fim, foram avaliadas condições de fermentação dos hidrolisados obtidos na hidrólise enzimática e fermentação e hidrólise simultâneas da biomassa pré-tratada. No pré-tratamento da biomassa as concentrações de glicose e xilose liberadas na hidrólise enzimática da biomassa pré-tratada, apenas com ácido sulfúrico, variaram de 6,2 a 19,1 g L-1 e 1,8 a 3,1 g L-1, respectivamente. A adição de pré-tratamento alcalino possibilitou aumento significativo da concentração de açúcares liberados. O uso apenas de pré-tratamento alcalino resultou em concentrações de glicose e xilose que não diferiram estatisticamente dos obtidos com pré-tratamento em duas etapas. As concentrações de 5-hidroximetilfurfural e furfural não diferiram significativamente entre os pré-tratamentos testados. Na hidrólise enzimática apenas a relação sólido:líquido apresentou efeito significativo nas concentrações de glicose e xilose. Os rendimentos de etanol obtidos pelo processo de sacarificação e fermentação simultâneas foram superiores aos obtidos quando a hidrólise e fermentação foram conduzidas em etapas separadas. Os maiores rendimentos de etanol foram obtidos com carga de sólidos de 200 g L-1, e 25 FPU g-1 na etapa de pré-hidrólise.
The growing energy demand brings the need for development of new renewable fuels, aiming to reduceemission of particles and pollutants into the environment as well as substitution of petroleum products. Nowadays, researches using lignocellulosic biomass have been developed with the objective of making the production process of second generation ethanol economically viable. Arundo donax L., is a perennial grass presenting high biomass production and ability of growing in different environments, which due to the cultivation characteristics, growth and productivity presents potential as raw material for production of second generation ethanol. The present work envisages to establish the best pre-treatment hydrolysis and fermentation conditions for the biomass of Arundo donax L. aiming to ethanol production. Three pretreatments were tested: acid pretreatment, acid pretreatment followed by alkaline pretreatment and alkaline pretreatment. Variables of each pretreatment were evaluated using central rotational composite design through response surface methodology.After optimization of the pretreatment conditions, the influence of enzymatic loading and solid-to-liquid ratio variables in the glucose and xylose yields by the enzymatic hydrolysis were evaluated. Finally, the fermentation conditions of the hydrolysates obtained in the enzymatic hydrolysis and simultaneous fermentation and hydrolysis of the pretreated biomass were evaluated The amounts of glucose and xylose released by enzymatic hydrolysis of the Arundo biomass obtained from acid pretreatment ranged from 6.2 to 19.1 g/L and 1.8 to 3.1 g/L, respectively. The addition of an alkaline pretreatment led to a higher yield from the enzymatic hydrolysis with the average glucose concentration 3.5 times that obtained after biomass hydrolysis with an acid pretreatment exclusively. The use of an alkaline pretreatment alone resulted in glucose and xylose concentrations similar to those obtained in the two-step pretreatment: acid pretreatment followed by alkaline pretreatment. There was no significant difference in 5-hydroxymethylfurfural, furfural or acetic acid concentration among the pretreatments. In the enzymatic hydrolysis, only a solid-to- liquid ratio showed a significant effect on glucose and xylose concentrations. The ethanol yields obtained by the simultaneous hydrolysis and fermentation process are higher than those obtained when the hydrolysis and fermentation were conducted in separate steps. The highest ethanol yields were obtained with solids loading of 200 g L-1, and 25 FPU g-1 in the prehydrolysis step.

Abstract (sommario):

Arundodonax (Giant reed Plant) contains cellulose, hemicellulose and lignin and considered as a biomass resources for biofuels. Cellulose is a polymer of several d-glucose linked units coupled with beta-1, 4 glycosidic bonds. The lignin must be broken down to obtain cellulose.Brown and white rot fungusbreak down lignin through a fenton mechanism using hydroxyl radicals. Current work explores degradation of cellulose byisolating microbial communities followed by inoculating 1% carboxymethyl cellulose (CMC) or arundodonax in nutrient media. The microbes demonstrate long-term viability using CMS or arundodonax the sole carbon source.Pretreatment with microbes result in enhanced enzymatic hydrolysis at 50 °C using commercial cellulase over time. The simple dinitrosalicylic acid assay method quantifies glucose, the main product of enzymatic hydrolysis.

Abstract (sommario):

Arundo donax is a rhizomatous perennial grass that invades riparian habitats and replaces native riparian vegetation. The galling wasp, Tetramesa romana (Hymenoptera: Eurytomidae), was selected for evaluation as a biocontrol agent of A. donax in 2009. However, knowledge is scarce on which factors influence host selection and oviposition in T. romana. Through my observations I documented distinct behavioral steps preceding emergence leading to oviposition in T. romana, and elicited an investigatory response in T. romana from plant volatiles extracted from A. donax. My results indicated that T. romana does use a chemical cue as a factor in host selection, but it is likely not the result of a species-specific constituent. Evidence from my study revealed that T. romana may use a physical cue in selecting a host as well. T. romana preferred round glass rods over flat glass slides, indicating that shape is an important factor in host acceptance.

Abstract (sommario):

Global warming is becoming a major threat for human and wildlife on Earth and scientists agree in considering anthropogenic greenhouse gasses emission as the main factor contributing to atmosphere and sea temperature increase. Arundo donax L. is the most promising species for second generation biofuel production in Mediterranean areas but up to now little was known about its genetics. In this study, we first explored the whole transcriptome of young shoot of Arundo donax under simulated drought stress through NGS technology. This allowed us to understand the general molecular mechanisms of early plant responses to osmotic stimulus. Through comparative analyses with major Poaceae species, we identified a set of 53 orthologs that can be considered as a core of evolutionary conserved genes important to mediate water stress responses in the family. Leveraging on the availability of this transcriptome, we developed a set of of reliable reference genes with high stability across different stress and/or tissues, to enable further functional studies in this species. We selected a candidate, named AdDWD1, that have the potential to play an important role in stress response by targeted protein degradation. Our results indicate that AdDWD1 is upregulated under osmotic and salt response in A. donax and its overexpression in Arabidopsis brought to a significant decrease in germination under salt and a growth retardation in ABA-containing media. Overexpression of AdDWD1 caused downregulation of DREB2A and SOS3, while it did not affect other stress-related genes, pinpointing a possible pathway-specific regulatory role of the gene. Taken together, these results suggest a strong relation of AdDWD1 with salt and osmotic stress response and an important role in the signalling pathway during early stress stages.

Abstract (sommario):

En los últimos años, es evidente la preocupación mundial sobre las emisiones de gases del efecto invernadero, especialmente CO2. Una de las principales acciones contaminantes es la quema de combustibles fósiles. Paradójicamente la economía mundial depende (directa e indirectamente) en gran medida de la energía derivada de estos combustibles, principalmente petróleo, carbón y gas natural (en medida progresiva). Los combustibles fósiles son finitos, aunque aún tenemos un margen de algunos años para agotarlos. Según los expertos, estamos entrando a una nueva era, que deja de lado los combustibles fósiles y en cambio, usa otras fuentes de energía alternativa, como por ejemplo: la biomasa para la producción de biocombustibles (segunda generación), la energía proveniente del sol y la energía obtenida con la fuerza del aire. Estas fuentes deben usarse en conjunto, no son excluyentes. Una de las decisiones más importantes de la reunión de la COP 21 en París, fue el acuerdo de la disminución progresiva de combustibles fósiles, dado que contaminan altamente el ambiente al liberar grandes cantidades de CO2. Los países industrializados, ya cuentan con algunas investigaciones de años atrás para emplear estas fuentes alternativas. En Europa y EEUU, en cuatro años, se debe incrementar el uso los biocombustibles 10 al 20 %. Por tanto, hacer uso de biomasa para la producción de biocombustibles es de principal interés. En el presente estudio, se trabajó con Arundo donax L., como cultivo energético para evaluar su rendimiento bajo estrés hídrico, a nivel fisiológico, bioquímico y molecular. Los resultados nos indican que A. donax tuvo un buen rendimiento a nivel de producción de biomasa, los parámetros fisiológicos no se ven excesivamente afectados, además que tienen un buena eficiencia en el uso del agua. Los resultados moleculares no proporcionaron mucha información en cuanto a genes de tolerancia a la sequía, sin embargo son resultados valiosos para las futuras investigaciones. Por tanto se puede recomendar a A. donax como un buen candidato a cultivo energético en el ambiente Mediterráneo.
In recent years, global concern about emissions of greenhouse gases, especially CO2, is evident. One of the main pollutants actions is the burning of fossil fuels. Paradoxically, the world economy depends (directly and indirectly) largely on the energy derived from these fuels, mainly oil, coal and natural gas (in progressive measure). Fossil fuels are finite, although we still have a margin of a few years to exhaust them. According to the experts, we are entering to a new era, leaving aside the fossil fuels and instead, uses other alternative energy sources, such as: biomass for the production of biofuels (second generation), energy from the sun and the energy obtained with the air force. These sources must be used together, they are not mutually exclusive. One of the most important decisions of the COP 21 meeting in Paris was the agreement of the progressive decrease in fossil fuels; because of highly pollute the environment by releasing large amounts of CO2. Industrialized countries have already some research done years ago to use these alternative sources. In Europe and the USA, in four years, the use of biofuels should be increased from 10 to 20%. Therefore, make use of biomass for the production of biofuels is a main interest. In the present study, we worked with Arundo donax L., as an energy crop to evaluate their performance under drought stress, physiological, biochemical and molecular level. The results indicate that A. donax is a good performance at the level of biomass production; the physiological parameters are not unduly affected; besides they have a good water use efficiency. The molecular results did not provide much information about genes of drought tolerance; however, results are valuable for future research. Therefore, A. donax can be recommended as a good candidate for energy crop in the Mediterranean environment.

Arundo donax is an invasive species that mostly impacts on sensitive riparian ecosystems. Arundo is also invasive in South Africa, though less is known about its ecology, biology, and impacts. Since California and the Western Cape of South AFrica have similar Mediterranean-type climates, we could assume that the impacts of Arundo on ecosystems in California are likely to be similar in the Western Cape, and that control methods used could be extrapolated for use in South Africa. This thesis attempted to determine what impact Arundo has on biodiversity at the community-ecosystem level.

Abstract (sommario):

For this study, the energy crops Miscanthus x giganteus, Arundo donax and Phalaris arundinacea were planted at sites across Wales. Non-destructive methods of estimating crop yields were developed the most significant relationship for Miscanthus was between mean shoot height and mean shoot dry weight, whereas for Arundo it was between mean shoot volume and mean shoot dry weight although these estimates were over-estimates of actual crop yield when scaled up to field size. Yield estimates were obtained from destructive sampling for Phalaris and these were shown to be under estimates of whole crop yield. Crop growth data were compared in relation to soil type, soil chemistry and climatic conditions. Soil clay content and soil preparation were identified as of utmost importance to Miscanthus and Arundo success, but had no effect on Phalaris crops. Both Arundo and Miscanthus showed sensitivity to air temperatures during the growing season. Delaying harvest of both crops produced material with decreased moisture and mineral content, although results were not significant in all cases. The nitrogen, phosphorus and potassium content of leaves were higher than that in the cane, and harvest following leaf abscission was recommended. Arundo did not senesce completely during the winter period, and produced harvested material with higher mineral content than Miscanthus. Both crops required further drying to meet moisture content requirements for combustion crops. Phalaris was the only crop to meet moisture content and mineral content threshold levels, although the results were not consistent across sites. Leaf chlorophyll content was significantly correlated to above ground plant mineral content. Organic and inorganic fertilisers were applied to the three crops, and produced no response in Phalaris. Both Miscanthus and Arundo increased growth in response to high phosphorus levels, and generally in response to high fertiliser applications. At recommended application rates cattle manure showed most effect.

Abstract (sommario):

As part of PGE-EBC-MTU collaboration of the testing program to fire up to 100% of biocoal in the 600 MW Boardman boiler we produced samples from the seven biomass feedstock: Arundo Donax (AD), wheat waste, corn waste, woody hybrid poplar, and bark from hybrid poplar, woody pine, and bark from pine. The various samples of biocoal were tested in a combustion chamber with the following results: (1) Biocoal was fired and burned providing temperature and gas concentration profiles similar to coal. (2) NOx emission from all biocoal originating from any type of biomass feedstock was found to be significantly lower than that from coal burning. (3) SOx emissions was found to correlate directly to sulfur content in the plant minerals, which is very small for all types of biomass tested. (4) Fouling was quite low for all biocoal tested, such that it can be handled with an optimized water cannons procedure. (5) Minerals in the biocoal were found to segregate from the carbon particles which means that slagging propensity can be predicted by the common slagging indices. (6) Carbon cycle analysis revealed significant reduction of CO2 when using these biomass feedstock types, particularly the bark types.

Abstract (sommario):

PGE in collaboration with EBC and MTU is carrying out a testing program to fire up to 100% of biocoal (torrefied biomass) in its 600 MW Boardman boiler. An important aspect of this program is the selection of suitable biomass feedstock from which biocoal will be produced, emphasizing potential problems of fouling and slagging in the boiler. We thoroughly tested seven different types of feedstock: Arundo Donax (AD), wheat waste, corn waste, woody hybrid poplar, and bark from hybrid poplar, woody pine, and bark from pine. It was found that all these material comprised significant amounts of soil (varying from 5–25% in weight) with low fusion temperatures and therefore must be avoided from flowing into the boiler. We developed a separation technology of the soil from the biomass and were able to obtain biomass feedstock only with the plant minerals. All separated biomass feedstock, from soil, showed mineral content that is respective to soil they grew at. Samples were characterized for ultimate and proximate analysis, ash content and analysis and fusion temperatures. AD, wheat, and corn showed high content of potassium and low flow temperatures and therefore may not be used at 100% firing test unless some of the mineral contents are removed to protect the boiler from corrosion and slagging. Woody and bark hybrid poplar were found to have high fusion temperatures; woody and bark pine showed flow temperatures around 2500°F. All four feedstock types can be used for 100% firing test, however, the ones which is mostly recommended are woody and bark hybrid poplar.
