"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):

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):

Lignocellulosic biomass represents one of the most important feedstocks for future biorefineries, being a precursor of valuable bio-products, obtainable through both chemical and biological conversion routes. Lignocellulosic biomass has a complex matrix, which requires the careful development of multi-step approaches for its complete exploitation to value-added compounds. Based on this perspective, the present work focuses on the valorization of hemicellulose and cellulose fractionsof giant reed (Arundo donax L.) to give second-generation sugars, minimizing the formation of reaction by-products. The conversion of hemicellulose to xylose was undertaken in the presence of the heterogeneous acid catalyst Amberlyst-70 under microwave irradiation. The effect of the main reaction parameters, such as temperature, reaction time, catalyst, and biomass loadings on sugars yield was studied, developing a high gravity approach. Under the optimised reaction conditions (17 wt% Arundo donax L. loading, 160 °C, Amberlyst-70/Arundo donax L. weight ratio 0.2 wt/wt), the xylose yield was 96.3 mol%. In the second step, the cellulose-rich solid residue was exploited through the chemical or enzymatic route, obtaining glucose yields of 32.5 and 56.2 mol%, respectively. This work proves the efficiency of this innovative combination of chemical and biological catalytic approaches, for the selective conversion of hemicellulose and cellulose fractions of Arundo donax L. to versatile platform products.

Abstract (sommario):

Abstract In the context of the growing demand for biomass, which is being encouraged by the EU directives on the promotion of the use of renewable energy, recent investigations have been increasingly focused on fast-growing energy crops. The aim of this study was to investigate the energy properties of three types of agricultural energy crops: Arundo donax L., Miscanthus × giganteus and Sida hermaphrodita. This investigation looked into the content of non-combustible and combustible matter, higher and lower heating values, lignocellulose content, and biomass macro-elements. The results indicate that the energy values of these crops are comparable, while their lignocellulose content shows significant variations. Thus, Arundo donax L. can best be utilised as solid biofuel due to its highest lignin content, while Miscanthus × giganteus and Sida hermaphrodita L. can be used for both liquid and solid biofuels production. As far as Arundo donax L. is concerned, a higher ash level should be taken into consideration.

Abstract (sommario):

Arundo donax L., the giant reed—being a long-duration, low-cost, non-food energy crop able to grow in marginal lands—has emerged as a potential alternative to produce biomass for both energy production, with low carbon emissions, and industrial bioproducts. In recent years, pioneering efforts have been made to genetically improve this very promising energy crop. This review analyses the recent advances and challenges encountered in using clonal selection, mutagenesis/somaclonal variation and transgenesis/genome editing. Attempts to improve crop yield, in vitro propagation efficiency, salt and heavy metal tolerance by clonal selection were carried out, although limited by the species’ low genetic diversity and availability of mutants. Mutagenesis and somaclonal variation have also been attempted on this species; however, since Arundo donax is polyploid, it is very difficult to induce and select promising mutations. In more recent years, genomics and transcriptomics data are becoming available in Arundo, closing the gap to make possible the genetic manipulation of this energy crop in the near future. The challenge will regard the functional characterization of the genes/sequences generated by genomic sequencing and transcriptomic analysis in a complex polyploid genome.

Abstract (sommario):

This paper presents the results of an experiment carried out in Southern Italy (Sicily) on the estimation evapotranspiration (ET) in pilot constructed wetlands planted with different species (Chrysopogon zizanioides, Myscanthus x giganteus, Arundo donax, Phragmites australis, and Cyperus papyrus). In the two monitored growing seasons, reference ET0 was calculated with the Penman-Monteith formula, while actual ET and crop coefficients were measured through a water balance and the FAO 56 approach, respectively. The highest average seasonal ET value was observed in Phragmites australis (17.31 mm d−1) followed by Arundo donax (11.23 mm day−1) Chrysopogon zizanioides (8.56 mm day−1), Cyperus papyrus (7.86 mm day−1), and Myscanthus x giganteus (7.35 mm day−1). For all plants, crop coefficient values showed different patterns in relation to growth stages and were strongly correlated with phenological parameters. Myscanthus x giganteus and Arundo donax showed a water use efficiency values significantly higher than those observed for the other tested species. Results of this study may contribute to select appropriate plant species for constructed wetlands located in semi-arid regions, especially when the use of reclaimed water and/or the use of aboveground biomass are planned.

Devemos conhecer detalhadamente a biomassa a ser utilizada em um processo, pois são essas características que irão fornecer informações para determinar o método a ser utilizado. Nesse contexto, o presente estudo objetivou a caracterização das biomassas de arundo, palha e casca de arroz quanto ao teor de celulose, hemicelulose e lignina antes e após o pré-tratamento. A caracterização foi feita de acordo com a metodologia descrita por Dunning e Dallas (1949) e os cálculos a partir das equações descritas por Sluiter et al. (2005). Os valores encontrados para as biomassas in natura foram, arundo 32,3% celulose, 41,5% hemicelulose e 20,9% lignina, para casca de arroz 30,4, 31,2 e 21,2% e palha de arroz 36,9, 36,8 e 13,3% respectivamente. Já para as biomassas pré-tratadas, os teores encontrados de celulose, hemicelulose e lignina foram arundo 69,5, 15,5 e 10,2%, casca de arroz 62,4, 22,7 e 14,8% e palha de arroz 78,4, 16,1 e 5,3% respectivamente. Para as biomassas pré-tratadas a fração de celulose aumentou em relação as biomassas in natura e a de hemicelulose e lignina diminuíram. Isto indica uma grande solubilização da fração hemicelulósica e de lignina, o que é desejável, já que neste estudo o objetivo é a produção de etanol de segunda geração através da fração celulósica.

Abstract (sommario):

AbstractGiant reed (Arundo donaxL.) has recently shown great potential as a feedstock for the bioenergy industry. However, beforeA. donaxcan be grown commercially, due to its invasive nature, management strategies must be developed to reduce the risk of unintended spread. This research was conducted in northeastern Oregon (USA) during two growing seasons. Nine control strategies were evaluated in a field that previously hadA. donaxas a crop. The control strategies included mechanical practices (stem cutting and rhizome digging), physical practices (covering with an opaque tarp), chemical practices (glyphosate applications at different rates and timings), and a combination of these practices. Spring samplings ofA. donaxregrowth in the season following treatments indicated that stem cutting in the spring without follow-up control practices provided no control. Covering plants with a tarp after cutting them (either with or without a glyphosate treatment after cutting) resulted in 96% control. Application of glyphosate alone also resulted in excellent control, although timing of application was an important factor for maximizing efficacy. The best results were found when the maximum dose (10.2 L ai ha−1) was split among two or three applications (>99% of control) compared with the maximum dose applied once (75% to 94%). Control was lower (73% to 89%) for two of the strategies that included mechanical practices, stem cutting + glyphosate and rhizome digging, in comparison to other strategies involving tarps and/or glyphosate applications (88% to 100%). Results indicated that it is very difficult to eradicate volunteerA. donaxin 1 yr, but very good control can be achieved with several of the strategies tested.

Abstract (sommario):

The quantitative description of local buckling of hollow plant stems requires the knowledge of Young's modulus in the longitudinal and tangential directions for the different tissues of which the stem is composed. For thick–walled stems the shear modulus for the radial–tangential plane is needed for an advanced treatment of the process of ovalization. The primary causes of failure can be predicted if critical compressive strains in the longitudinal direction and critical tensile strains in the tangential direction are known. All of these mechanical properties and their variation along the length of the stem can be measured in Arundo donax .

Abstract (sommario):

The potential of a biosorbent derived from Arundo donax stem, a readily available agricultural product, was examined to remove Cr(VI) from water. Various techniques such as XRD, FTIR, SEM, and EDX were used for the characterization of the prepared adsorbent. The optimal pH for Cr(VI) biosorption was found to be 2.0. The experimental data best suits the Langmuir isotherm model and pseudosecond-order kinetics. The maximum biosorption capacity (qmax) of the investigated biosorbent for Cr(VI) was evaluated to be 76.92 mg/g by the Langmuir model. From the results of the Cr(VI) biosorption using charred Arundo donax stem powder (CADSP), it can be a novel, cost-efficient, and effective material for removing Cr(VI) from water and wastewater.

Abstract (sommario):

Wild Cane (Arundo donax) is a perennial rhizomatous grass that is native to tropical and sub-tropical zones. This C3 crop is known to have significant potential to produce commercial grade bioenergy. Belize has conducted a preliminary compatibility test at the American Sugar Refineries/ Belize Sugar Industries, Belize Co-generation Energy Ltd. (ASR/BSI BELCOGEN) facility which produced satisfactory but inconclusive results. The potential of this species as an energy crop is enhanced by its versatility, adaptability and its robustness to climate variability. Further, the crop’s resistance to environmental stresses and its ability to flourish on marginal spaces means that successful propagation will not lead to competition for productive agricultural lands, and potentially consequential negative effects on Belize’s food security. The goal of this study was to evaluate the feasibility of the commercial cultivation of Arundo donax as an alternate fuel source for cogeneration at BELCOGEN in Belize, focusing particularly on biomass yield and the identification of climate and other environmental factors required for optimum growth. In this regard, the research examined three sites comprising natural stands of Arundo donax - Middlesex, Sittee River and Monkey River. The species demonstrated good productivity potential, particularly within the Middlesex and Sittee River areas. Biomass yield was estimated at 15.18 t ac-1, 4.76 t ac-1 and 3.45 t ac-1 for Middlesex, Sittee River and Monkey River, respectively. In this study, the main parameters examined were climatic conditions and soil analysis, specifically moisture content, soil type and pH. Different growth patterns were noted at the three sites with the number of stems and extrapolated yield varying from 9.8 t ac-1, 10.45 t ac-1 and 32.02 t ac-1 for Monkey River, Sittee River and Middlesex, respectively. The adaptability of the species to marginal lands, the limited human input needed for its cultivation, and its high biomass yield are factors which make Arundo donax a potentially viable fuel crop.

Abstract (sommario):

Due to manganese mining and slag accumulation, the geological structure of the wetland polluted by heavy metals in Xiangtan Manganese Mine area was seriously damaged, hence biodiversity loss, severe soil, and water pollution, as well as serious heavy metal pollution to food, vegetables, and other natural sources. In order to restore the ecological environment of the mining area, in 2015, the ecological restoration test of heavy metal polluted wetlands in the mining area was carried out. The results showed that the Mn content of different parts of Koelreuteria paniculata root from high to low order: fine root > small root > medium root > large root. The Mn content of different parts of Elaeocarpus decipiens root from high to low order: large root > medium root > small root > fine root. The order of Mn content in plants of the wetland restoration from high to low is as follows: Canna warscewiezii > Thalia dealbata > Boehmeria > Pontederia cordata > Typha orientalis > Nerium oleander > Softstem bulrush > Iris germanica > Acorus calamus > Arundo donax > Phragmites australis; The order of Internal Cu content from high to low is as follows: Acorus calamus > Thalia dealbata > Softstem bulrush > Canna warscewiezii > Typha orientalis > Arundo donax > Boehmeria > Iris germanica > Pontederia cordata > Nerium oleander > Phragmites australis; Zn content from high to low order is as follows: Canna warscewiezii > Acorus calamus > Thalia dealbata > Typha orientalis > Pontederia cordata > Arundo donax > Softstem bulrush > Iris germanica > Boehmeria > Phragmites australis > Nerium oleander; Cd content from high to low order is as follows: Phragmites australis > Softstem bulrush > Thalia dealbata > Nerium oleander > Boehmeria > Canna warscewiezii > Acorus calamus > Iris germanica > Typha orientalis > Pontederia cordata > Arundo donax. The results of this study have provided a theoretical basis and decision-making reference for the evaluation of heavy metals polluted wetland restoration, protection, and reconstruction effects and the selection of ecological restoration modes.

Abstract (sommario):

Entre los principales impactos ambientales derivados de la operación de edificios habitacionales está la generación de gases de efecto invernadero resultante del consumo eléctrico de sistemas de climatización. El uso de sistemas de vegetación representa una alternativa para disminuir dicho consumo energético. Las barreras verdes son sistemas de vegetación empleados como protección contra el viento, aunque recientemente se ha explorado su uso como sistemas de amortiguación acústica. En este trabajo se analiza su posible aplicación como sistemas de aislamiento térmico para edificios. En específico, se reporta el comportamiento de una barrera verde de Arundo donax como elemento de bioclimatización. Los resultados se analizan a partir de las temperaturas medidas en el interior y exterior de edificios prototipo, en función de la presencia de una barrera verde. Adicionalmente se determinó la traspiración del Arundo donax en condiciones ambientales extremas.

Abstract (sommario):

The study on the wetland plant species and their resistance is the key to ecological wastewater treatment technology. The study on the effects of wastewater duress on the physical and chemical properties of constructed wetland plants and the anti-stress capability of constructed wetland plants can provide theoretical basis and technical support for constructed wetland plant material selection. By adopting surface flow constructed wetland system, the effects are studied on MDA in 4 common plants in Shandong (Phragmites communis, Typha oriental, Arundo donax and Canna generalis) in different wastewater duress time. The results show: All in all, Phragmites communis and Canna generalis have stronger anti-stress capability, while Arundo donax and Typha oriental has weaker anti-stress capability; but as wastewater duress time increases, the anti-stress capability of Phragmites communis decreases, while the anti-stress capability of Canna generalis increases.

Testo completo

Abstract (sommario):

Phylogenetic relationships of the whole Poaceae family inferred from the sequence data of rDNA (ITS) support the hypothesis that the arundinoids are monophyletic, not polyphyletic as previously proposed. The ITS sequence phylogeny of 42 arundinoid species demonstrates an early divergence of the Aristideae and three major groupings, corresponding loosely to the tribes Aristideae, Arundineae and Danthonieae. The Arundineae are resolved into two paraphyletic clades. In one clade, Arundo, Monachather, and Dregeochloa are the sister group to Amphipogon and Diplopogon. In the other clade, Phragmites, Molinia, Gynerium, Thysanolaena, Spartochloa, and Cyperochloa are the sister group to Eriachne and Micraira. Arundo is not closely related to Phragmites. The Danthonieae clade, including taxa from Africa, Australia, New Guinea, New Zealand, the South American Cortaderia, and the North American Danthonia, appears to be monophyletic. However, the genus Merxmuellera is polyphyletic.

Testo completo

Abstract (sommario):

In the last years, natural fibers are increasingly investigated as an oil recovery system in order to overcome the oil spillage phenomena, thus preserving environment and aquatic life. In particular, lignocellulose-based fibers have recently been employed with promising results. In such a context, the aim of this paper is to assess the oil sorption capability of natural fibers extracted from the stem of the giant reed Arundo donax L., a perennial rhizomatous grass belonging to the Poaceae family that grows naturally all around the world thanks to its ability to tolerate different climatic conditions. Sorption tests in several pollutants and water as a reference were carried out. The fibers have absorption capacities that are about five to six times their weight. Depending on the high absorption kinetics, possible applicative interests can be identified. Eventually, depending on the fiber size, adsorption properties were related to the microstructure and morphology of Arundo donax fibers.

Abstract The changes of selected chemical parameters were observed in Gleyic Fluvisols. The field experiment was established as a twofactor experiment with four energy crops (Arundo donax L., Miscanthus × giganteus, Elymus elongatus Gaertner, Sida hermafrodita) and two variants of fertilization (nitrogen fertilization in rate 60 kg ha-1, without nitrogen fertilization). Soil samples were taken from the depth of 0 to 0.3 m at the beginning of the experiment in the autumn 2012 and at the end of reference period in the autumn 2015. Land management conversion from market crops to perennial energy crops cultivation has influenced changes of selected soil chemical parameters. The contents of soil organic carbon were affected by cultivated energy crops differently. It was found out that Arundo increased the organic carbon content and Miscanthus, Elymus and Sida decreased its content. At the same time, the same impact of the crops on content of available phosphorus and potassium and soil reaction was found. It was recorded that each cultivated crop decreased the soil reaction and available phosphorus content and increased the content of available potassium.

Abstract (sommario):

Summary The effect of solvent on yield and properties of ethanol-alkali pulps from Arundo donax L. was studied. Selectivity of pulping was significantly improved with increase in solvent proportion in the cooking liquor. A rise in ethanol concentration from 20 to 60% (by vol.) increased pulp yield from 44.0 to 48.9%, while decreasing residual lignin from 5.0 to 3.0%. Ethanol addition had a positive effect on preservation of carbohydrate complex against degradation in alkaline medium. Intrinsic viscosity of cellulose was improved up to 35% and xylan content increased from 8.6 to 12.1% with increase in ethanol concentration from 20 to 60%. The preservation of minor non-cellulosic polysaccharides with solvent addition was also observed. The papermaking properties of ethanol-alkali pulps were best for 20% ethanol content. An increase in solvent charge led to a drop in burst, tear and tensile pulp strength. Solvent addition assisted the conversion of glucuronic to hexenuronic acids, whereas the content of HexA in ethanol-alkali pulps of Arundo donax (about 10 μmol/g) was substantially lower than reported for kraft pulps from wood.

Testo completo

Abstract (sommario):

Arundo donax (giant reed) is an herbaceous, perennial and non-food crop producing dry biomass with relatively high yields in many regions and under different climates. Although there exists a large amount of literature on A. donax, the economic aspects are somehow neglected or are very much limited in most papers. Therefore, the aim of this paper is to analyse the economics of A. donax by applying a systematic literature review of the field. Our sample consists of 68 relevant studies out of the 6009 identified, classified into four groups: Bioenergy, agronomy, invasiveness and phytoremediation. Most papers were focusing on Italy and on the Mediterranean region and were written on the bioenergy aspect. Most studies suggest that A. donax has a relatively high energy balance and yields, high investment but low maintenance costs and high potentials for phytoremediation of contaminated soils. However, a certain section of the literature, mainly based on US experience, shows that giant reed should be produced with care due to its invasiveness hazard. On the whole, A. donax was found to have high economic potentials for biomass production in marginal as well as disadvantageous lands operated by small farmers in the Mediterranean region.
