Lipid Yield and Composition of Azolla filiculoides and the Implications for Biodiesel Production

摘要: The aquatic fern Azolla is one of the fastest-growing nitrogen-fixing plants on Earth and therefore considered as a potential source biomass for bioenergy production. lipid fraction from filiculoides was analyzed to investigate whether it suited biodiesel Since productivity further increased at higher CO2 concentrations, A. produced 800 ppm mimicking cultivation system utilizing waste industry. harvested contained 7.92 ± 0.14 % dry weight (dw) crude lipids. Drying conditions did not significantly affect composition or yields, indicating that drying may be energetically optimized without risk product loss. Total extracts 4.2 0.38 free fatty acids. Of fraction, 41 13 consisted acids were converted into acid methyl esters upon saponification in methanol. Unique mid-chain (di)hydroxy compounds constituted 7.2 2.8 Based profile, estimated meets requirements set by EN14214 standard fuel density, cetane number, iodine value. cold filter plugging point (CFPP), however, expected too high due relatively concentrations lignoceric presence compounds. To produce high-quality lipids, therefore, fractionation step will required removing these As an advantage, long-chain alcohols obtained after provide valuable secondary stream with applications chemical industry nutrition.
