; Santos, M.C.R. Request PDF | The Transcriptome in Landoltia punctata | Research on Lemnaceae (duckweeds) is hot spot recently due to its application potential in bioenergy production and phytoremediation. Pyrolysis represents an efficient alternative strategy for biofuel production from species with tough cell walls such as fungi and fungal-algal pellets. ; Park, J.; Heubeck, S.; Ralph, P, nutrient removal in wastewater treatment high rate algal ponds of three di. The performance of, was associated with a final pH decrease from 7.5 to, two-fold under decreased partial pressure compared, of the enzymatically saccharified hydrolysate under decreased pH. 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. measured using the ion chromatography system Dionex ICS-1100 (Thermo Scientific, W, USA). Among several sustainable resources, marine heterotrophic microorganisms have gained much interest for various commercial applications owing to their potential to produce high quantities of polyunsaturated fatty acids. Biotechnology for Biofuels, May 2013 Three common Australian aquatic plants, duckweed (Landoltia punctata), elodea, (Elodea cana-densis) and water clover (Marsilea quadrifolia), colonizing different depths of wetlands were It can either grown with the rice plantation as an intercrop or included in the soil well before the plantation of rice. Above 70% of the globally produced fish oil is utilised for aqua feed formulations. 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. The experiments were terminated after 48 h. as a feedstock for biohydrogen production [, for biohydrogen production. Results. Morphological characterisation along with molecular identification revealed that these strains showed close similarity to Aurantiochytrium spp. However, based on anindependent T-test analysis, the cellulose contents of plants grown in different media were not significantlydifferent. They are an unusual group because their cell wall has very low levels of lignin while accumulating apiogalacturonan, a pectic polysaccharide that could be involved with boron assimilation. Abstract. The high productivity, the ability to grow on wastewaters and unique chemical composition make Azolla species the most attractive, sustainable and universal feedstock for low cost, low energy demanding, near zero maintenance system for the production of a wide spectrum of renewable biofuels. Pistia stratiotesshowed the highest total nitrogen removal of 63.15% from the treated effluent. Aquatic plants are attracting, attention as feedstock for biohydrogen production because of their biomass yield and biochemical, However, some wastewaters, like those resulting from the textile dyeing, finishing, and laundry. This was associated with a pH decrease to 5.64. It possesses a cavity in the dorsal leaves for the blue-green algae (Anabaena algae) that is capable of fixing atmospheric nitrogen through the symbiotic association with Azolla i.e. Landoltia punctata, a widely distributed duckweed strain with the ability to accumulate starch, was used as a novel feedstock for bioethanol production by Saccharomyces cerevisiae. Shrimp Toxicity Tests of Treated Wast, , as biosensors of the treated wastewater’s. Evaluación del uso de Landoltia punctata en el pulido de efluentes de sistemas de tratamiento biológico con el fin de eliminar nutrientes y mejorar aún más la biomasa obtenida de poscosecha. S. polyrhiza and L. punctata biomass showed higher ethanol (0.168-0.191, 0.166-0.172 and 0.174-0.191 g-ethanol/g-biomass, respectively) and methane (340-413 and 343-408 NL CH4/kg VS, respectively) production potentials than the others, which is related to their higher carbon and starch contents and calorific values. We found that the faster-growing species (the Lemnoideae) accumulate lower starch and higher soluble sugars than the slower-growing species within the Wolffioideae. �i�g䥣��\e�;;�-JNAU�+��uΤ��i��j�!���Ѝ�)o�`�i�"Oʨ§q�0���y����Q|(��)6�$��� ����玳�L�tMBSw��Go"��@U� M�E΍i�ԓL�)1�\4j�k�ܣv�ySSp�>.���1t�B��l finishing and laundry detergent industries.

A comparative analysis was performed by measuring their relative growth rates (RGR), and their content for starch, as well as soluble and cell wall carbohydrates. toxicity tests were performed under static conditions in 500 mL glass beakers for 96 hours. Compared with other duckweed species, Landoltia punctata had significant advantage in starch accumulation. Treatment of different types of wastewaters with biofilms showed a reduction in the concentrations of key nutrients, such as phosphates, ammonia, nitrates, selenium and heavy metals. S. polyrhiza showed the highest nitrogen removal (2.0-10.8 mg T-DIN/L/day) and biomass production (52.6-70.3 mg d.w./L/day) rates in all the three effluents. As the fastest growing plant, duckweed can thrive on anthropogenic wastewater. All rights reserved. Miranda Ana F , Ram Kumar N , Spangenberg German, Subudhi Sanjukta, Lal Banwar, Mouradov Aidyn.

The basic and environmentally friendly solutions are to using the potential of soil microbes. Pereira, A.L. Comparative transcriptome analysis to investigate the high starch accumulation of duckweed (Landoltia punctata) under nutrient starvation Biotechnol Biofuels. Although starch accumulation and heavy metal absorption by L. punctata have been studied at biochemical and physiological levels for many years, the underlying mechanism has not been subjected to omics analysis until recently. Both daily areal nutrient removal and biomass production were affected by the size of the pond. However, the molecular biological basis of high flavonoid and low lignin content remains largely unknown, as does the best method to combine nutrients removed from sewage and the utilization value improvement of duckweed biomass.

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. The volumetric hydrogen production increased, to the previous batch experiment. Aquatic plants which can rapidly colonize wetlands are attracting attention because of their ability to grow in wastewaters and produce large amounts of biomass. Conclusions Growth of Azolla in contaminated water results in the removal of total phosphorous and nitrogen with the growth rate of 0.43 t P/ha-yr and 2.6 t N/ha-year, respectively. the conversion of wastewater nutrients to valuable biomass: Chen, Q.; Jin, Y.L. Structurally, these biofilms represent complex consortia of unicellular and multicellular, photosynthetic and heterotrophic inhabitants, such as cyanobacteria, microalgae, diatoms, bacteria, and fungi. Starving changed the yield and composition of the fatty acid as a result of re-direction of carbon flow from fatty acid to anthocyanin pathways. A new thraustochytrid. Cellulose and lignin contentswere higher in the Hoagland's solution treatment when compared with the effluent. ResultsThe growth of Azolla filiculoides in synthetic wastewater led up to 25, 69, 24 and 40 % reduction of NH4–N, NO3–N, PO4–P and selenium, respectively, after 5 days of treatment. DNAs were sequenced with next-generation sequencing. Duckweed (Landoltia punctata) has the potential to remediate wastewater and accumulate enormous amounts of starch for bioethanol production.
