| Abstract: | This study presents lipids from Oscillatoria annae BDU6, a freshwater cyanobacterium, to generate biodiesel. Efficient oil extraction from O. annae was achieved by ultrasonication in combination with organic solvents (50.9%) than homogenization (40.4%). Efficient conversion of triglycerides of O. annae into biodiesel was obtained by alkali mediated transesterification (86% w/v) when compared with lipase-mediated transesterification (76.5% w/v). RSM and CCRD were employed to optimize the growth medium to improve biomass of O. annae, which resulted in 3.2-fold increase in biomass yield (5.3 g-l dry wt/g of inoculum) compared to initial level (1.6 g-l dry wt/g of inoculum). |
