The shortage of fossil fuel has promoted the development of alternative biofuels such as biodiesel and bioethanol. Biodiesel is an environment benign fuel produced from renewable resources such as microalgae. Fatty acid methyl esters (FAMEs), called biodiesel, can be prepared by the transesterification of triglycerides from microalgae with short-chain alcohols such as methanol as acyl acceptor. In the synthesis of FAMEs by transesterification using lipase, glycerol was simultaneously produced as a byproduct. Glycerol is subjected to coat the lipase, causing mass-transfer limitation of the reaction. Glycerol carbonate was synthesized from glycerol and dimethyl carbonate (DMC) by lipasecatalyzed transesterification. DMC can be choice of solvent for extracting oil from microalgae biomass because DMC has a good extraction solvent and the substrate for simultaneous synthesis of FAMEs and glycerol carbonate. Extraction efficiency was improved by using DMC together with methanol. The reaction conditions for the production of FAMEs were optimized.
