Mixed microalgae consortia growth under higher concentration of CO2 from unfiltered coal fired flue gas: Fatty acid profiling and biodiesel production.

摘要: Biodiesel is produced by transesterification of fatty acid methyl esters (FAME) from oleaginous microalgae feedstock. fuel properties were studied and compared with biodiesel standards. Qualitative analysis FAME was done while cultivating mixed consortia under three concentrations coal fired flue gas (1%, 3.0% 5.5% CO2). Under 1% CO2 concentration (flue gas), the content 280.3 μg/mL, whereas lipid 14.03 μg/mL/D (day). Both FAMEs contents low at other (3.0 5.5%). However, in presence phosphate buffer (PB + FG) showed higher saturated acids (SFA) (36.28%) unsaturated (UFA) (63.72%) versus concentration, which might be responsible for oxidative stability biodiesel. Subsequently, cetane number (52) iodine value (136.3 gI2/100 g) along 50 mM found accordance European (EN 14214) standard. Results revealed that significantly enhanced quality, but reduced yield. This study intended to develop an integrated approach significant improvement quality surplus phosphorus utilizing waste (as source) using microalgae. The sequestration industrial not only greenhouse gases, may also ensure sustainable eco-benign production
