The purple-backed duckweed, Landoltia punctata, is rich in starch and flavonoids. 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 fermentation of treated L. punctata biomass by Enterobacter cloacae yielded up to 2.14 mol H2/mole of reduced sugar, which is comparable with leading terrestrial feedstocks. Namely, the water quality improved to Grade II under the Chinese standard. In order to better understand the differences in reported productivity, the performance of three different size wastewater treatment high rate algal ponds (5 m², 330 m² and 1-ha) were assessed with respect to nutrient removal and microalgal productivity over three seasons.

Calvert, H.E. The accumulation rate of the polyculture was significantly higher than that of Duckweed is a valuable feedstock for bioethanol production due to its high biomass and starch accumulation. An increase in substrate, plained by the higher production of ethanol and, drogen production [99–102]. Microalgae have shown clear advantages for the production of biofuels compared with energy crops. acid and triacylglycerol composition and content of 30 duckweed species and cloning of a Delta 6-desaturase. standard deviation, * Significance levels: plants were added in amounts enough to cover the surface of the plastic containers, , shows no significant reduction in TP since TN is a limiting factor, led to 65% uptake of Se from 100% SeSW and 84%, mg Se/g DW from 2.5 mg/L Se solution [85]. 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. Results We found that L. punctata can accumulate starch rapidly accompanied by alterations in endogenous hormone levels after uniconazole application, but the relationship between endogenous hormones and starch accumulation is still … In this study, 11 strains of heterotrophic thraustochytrid capable of producing significant quantities of polyunsaturated fatty acids were successfully isolated from different mangrove habitats along the southwest coast of India.

Three common Australian aquatic plants, duckweed (Landoltia punctata), elodea, (Elodea cana-densis) and water clover (Marsilea quadrifolia), colonizing different depths of wetlands were 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. Aquatic plants which can rapidly colonize wetlands are attracting attention because of their ability to grow in wastewaters and produce large amounts of biomass. finishing and laundry detergent industries. Salt, D.E. Liquid biofuels, such as bioethanol, converted from bio-mass are considered as a promising alternative for trad-itional fossil fuels.

This can be explained by the higher production of ethanol and, short-chain organic acid as co-products during hydrogen production [, Soluble metabolites production during hydrogen production by, partial pressure. biofuel feedstock by enzymatic hydrolysis. 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. However, Lemna sp. Duckweed (Landoltia punctata) was collected from ponds in Huilong Town, Xinjin County, Chengdu, China, and was cultivated to accumulate starch, and then was dried at 60 °C and crushed into powder. Among the five genera of duckweed, Landoltia punctata has great potential in starch production and heavy metal bio-extraction. The utilization of Azolla is profitable due to its dependency on natural reservoirs and usefulness for the production of flooded rice as well as bio- and phytoremediation potentiality in agronomy. 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. could not be further utilizedbecause the plants could only be cultured for 13 days. 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. �Z�. Use of duckweed (Landoltia punctata) as a fermentation substrate for the production of higher alcohols as biofuels. Engineering Corynebacterium crenatum to produce higher alcohols for biofuel using hydrolysates of duckweed (Landoltia punctata) as feedstock. The chloroplast genome comparison demonstrated that the differences in chloroplast genome sizes among the Lemnoideae primarily resulted from variation in non-coding regions, especially from repeat sequence variation. In this work, five duckweed species from different genera (Spirodela polyrhiza, Landoltia punctata, Lemna gibba, Wolffiella caudata, and Wolffia borealis) were cultivated under two light intensities (20 and 500 μmoles of photons m−2 s−1) to evaluate the effects of growth rate on carbohydrate metabolism. * Significance, acid-treated prehydrolysate and enzymatically, yields were observed from 30% substrates: 32.48. eated prehydrolysate, respectively (Figure 4). As the fastest growing plant, duckweed can thrive on anthropogenic wastewater. Collected dry biomass was used as an alternative carbon source for heterotrophic marine protists, thraustochytrids, which produced up to 35% dry weight of lipids rich in palmitic acid (50% of total fatty acids), the key fatty acid for biodiesel production.
