Abstract: Biodiesel is an important approaches for substitution of fossil energy, however, high raw material cost restricts its further application. Microbial lipid is ideal biodiesel raw material because of its quality of sufficient supply, cheapness and none farmland consuming. In this paper, we summarized resent progress in microbial lipid extraction and determination, detailed reviewed the applications of transposon tagging, metabolic pathway control, transcription factor control and fermentation optimization in cellular lipid accumulation, discussed the possibility and advantages of biodiesel production using microbial lipid.

Key words: Microbial lipid, Biodiesel, Lipid determination, Metabolism pathway control
