The aquatic plant Azolla became increasingly popular as bioenergy feedstock because of its high growth rate, production of biomass with high levels of biofuel-producing molecules and ability to grow on marginal lands. Microbial Cell … Azolla-Anabaena. newly isolated alkaline tolerant anaerobe, Mandal, B.; Nath, K.; Das, D. Improvement of biohydrogen production under decreased partial pr. Terrestrial crops that are rich in carbohydrates, such as cellulose and starch, were widely used for hydrogen production. was investigated. Aquatic weeds have an exceptionally higher reproduction rates and are rich in cellulose and hemicellulose with a very low lignin content that makes them an efficient next generation biofuel crop. Shrimp Toxicity Tests of Treated Wast, , as biosensors of the treated wastewater’s. A. filiculoides and L. punctata can be used as a new generation of feedstock, which can treat different types of wastewater and represent renewable and sustainable feedstock for bioenergy production. As a result, significantly higher total yields of lipids were detected in Azolla filiculoides and Azolla pinnata at the reproductive stage. %���� performed by using a 30% concentration of substrates. 77–87. and P in media showed that the greatest uptakes of both key nutrients were observed in the duckweed, experiment, which can be explained by the additive e, phytoremediation which completely suppresses algal growth in treated wastewater e, Application of duckweed and Azolla representatives for biodiesel production is not economical, because of low lipid yields (5–11% DW for, carbohydrate content makes these aquatic plants a potential feedstock for oleaginous heterotrophic, representatives contain 6% DW of starch and up to 35% DW of cellulose. Microalgal biomass productivity reported in full-scale studies (1-ha or greater) have often been substantially lower than that reported from smaller scale ponds in similar climates, regardless of the season or the dominant microalgal species used. �]fBʼn���1lj�����/U^w�s8�*���=�6�7MՕ9���˻�,^E8����� �E�Ri(�,� �����MU9d�����X5�ƴPJ�G��|�U٬^7��9t��֚[����$��Μr�ǎ��auM��h�� bt��M�8^0����+)�R��]y FlKD�H�Q�.������m���~�k����.�02�Nq�4�4+�0������zثp��c�X�@����gǙ���?w��,�"��h� uN��B-V�mӏ��k_�����ks�;�J��P�}��c���9�2Y��C|�׿?vN����f[�C�A������&�[I U��٫�>凒q�ͫsx#��"�A��F�Ȧ-�������]s��tl=�.����,���A��c��EƱи�J±�草��K1�rp�p�ș�u�m�j�*���ԅi�����WG���{?���i;���w�c{v�޼�R�v�;�*�ve'��(��p�1c"�B�X�"�&r~�+7[�}_�W�ty�0xuf�i!xzF�қ�����o��ă��j�4RʀA������}���|] Conclusions Comparative transcriptome analysis to investigate the high starch accumulation of duckweed (Landoltia punctata) under nutrient starvation Biotechnol Biofuels. Güsewell, S. N:P ratios in terrestrial plants: Güsewell, S.; Gessner, M.O. N:P ratios influence litter decomposition and colonization by fungi and bacteria, phosphorus removal in duckweed-covered domestic wastewater, Ohlendorf, H.M.; Hothem, R.L. To assess the potential of duckweeds as agents for nitrogen removal and biofuel feedstocks, Spirodela polyrhiza, Lemna minor, Lemna gibba, and Landoltia punctata were cultured in effluents of municipal wastewater, swine wastewater, or anaerobic digestion for 4 days. expression data for plants grown in soil amended with biochar, of pistia stratiotes biomass within a biorefinery, Mukherjee, B.; Majumdar, M.; Gangopadhyay, A.; Chakraborty, Costa, M.L. showed the highestphosphorus removal of 36.15% from the treated effluent. In both cases, the hydrogen production rates increased exponentially between 12, and 24 h followed by the stationary phase at 24 h, wh, production of metabolites such as acetic acid and, terminated after 48 h. Terrestrial plants have been widely explored for use as a feedstock for. Background Use of Duckweed (Landoltia punctata) as a Fermentation Substrate for the Production of Higher Alcohols as Biofuels Haifeng Su,† Yun Zhao,† Juan Jiang,† Qiuli Lu,† Qing Li,† Yao Luo,† Hai Zhao,*,‡ and Maolin Wang*,† †Key Laboratory of Bio-resources and Eco-environment of the Ministry of Education, College of Life Sciences, Sichuan University, Lipid extraction and fatty acid composition were analysed according to Miranda et al. in the containers covered by the Azolla plants. Characterization of natural biodiversity of duckweed species is essential for the germplasm preservation and various practical applications. Its incorporation also enhanced the effectiveness of other chemical fertilizers. An increase in substrate, plained by the higher production of ethanol and, drogen production [99–102]. Ecological responses and remediation ability of W, Pagliuso, D.; Grandis, A.; Igarashi, E.S. Na, azollae symbiotic association during salt toxicity, Gupta, A.; Wilkens, S.; Adcock, J.L. It was a promising starch feedstock for alcohol fermentation. The experiments were, ) Hydrogen production by E. cloacae DT-1 fr, om different concentrations of acid-treated, biomass can produce up to three times as many lipids and, were obtained from the collection of aquatic plants at RMIT, , were added, starting an additional period of five days of treatment. Su H, Zhao Y, Jiang J, Lu Q, Li Q, Luo Y, et al. of Idaho, 315 Fall Ave. East, Twin Falls, ID, 83303 USA . Dhillon, K.S. Given the high annual productivity of Azolla, hydrothermal liquefaction can lead to the theoretical production of 20.2 t/ha-year of bio-oil and 48 t/ha-year of bio-char. 18,29 According to the data of average starch accumulation rate in this study, the annual starch yield of L. punctata K3 could reach 11.35 DW t ha −1. The aim of this study was to enhance the duckweed biomass (Landoltia punctata), produced in wastewater treatment system, by enzymatic hydrolysis of its starch and cellulose into fermentable sugars. Among the five genera of duckweed, Landoltia punctata has great potential in starch production and heavy metal bio-extraction. The duckweed powder (starch content 47.8%) was hydrolyzed using 1% … As a r, that duckweed and Azolla can have additive and co, The combination of TN, TP, nutrients and sunlight often leads to microalgal and cyanobacterial, blooms, which are highly undesirable contaminants, the potential to suppress microalgal/cyanobacteria, penetration beneath the plants and (ii) the concentrations, of duckweed and Azolla on algal growth, we gr, with 100% mortality observed at concentrations, compared to untreated SeSW). The aquatic plants, Azolla filiculoides, and Landoltia punctate, were used as complementing phytoremediators of wastewater containing high levels of phosphate, which simulates the effluents from textile, dyeing, and laundry detergent industries. Bacterial growth was detected by measuring the optical density at 600 nm in a spectrophotometer, The biogas composition generated in the headspace and the soluble metabolites generated during the, dark fermentation process were detected by gas chromatography by following the protocols r, USA) equipped with a flame ionization detector and DB-W, C. The injector and detector temperatures were maintained at 250. The biomass dry weights were determined immediately after sampling by drying samples at, Liquid SeSW samples were filtered through a 0.45, m syringe filter and acidified with concentrated, C. Plants from each treatment were rinsed twice with Milli-Q water, and a sub-sample of 100 mg was weighed into glass tubes and digested with HNO, temperature, samples were filtered using a 0.45, m syringe filter and diluted to 10 mL with Milli-Q, water. In this book, the soil microbes and their beneficial effects on plant growth in several chapters, various microbes such as rhizobacteria, mycorrhizal fungi, Azolla, etc., and the mechanisms used by them to stimulate plant growth were discussed. Authors: Yang Liu, Yang Fang, Mengjun Huang, Yanling Jin, Jiaolong Sun, Xiang Tao, Guohua Zhang, Kaize He, Yun Zhao, Hai Zhao Abstract: Landoltia punctata is a widely distributed duckweed species with great potential to accumulate enormous amounts of starch for bioethanol production. Methods Like Spirodela polyrhiza and Landoltia punctata, there are no obvious intraspecific genome size variations in Wolffiella hyalina and Wolffiella lingulata. ; Raskin, I. Phytoremediation. Total dissolved inorganic nitrogen (T-DIN) of 20-50 mg/L in effluents was effectively removed by inoculating with 0.3-1.0 g/L duckweeds. The biomass of fungal-algal pellets grown on swine wastewater was used as feedstock for the production of value-added chemicals, biogas, bio-solids and liquid petrochemicals through pyrolysis. Morphological characterisation along with molecular identification revealed that these strains showed close similarity to Aurantiochytrium spp. 2013 May 8;6(1):72. doi: 10.1186/1754-6834-6-72.
