PRODUCTION OF BIODIESEL FROM LIPASE MEDIATED TRANSESTERIFICATION BY REDUCING FREE FATTY ACID CONTENT OF ALGAL OIL PRODUCED FROM BOTRYOCOCCUS BRAUNIISHIVANDAPPA, PUSHPA AGRWAL, V. KRISHNA AND S. VIDYASHREEAbstract Increasing demand in transport fuel lead to discovery of Jatropha, Pongamia plants along with Microalgae for biofuel production. In the present work Biodiesel was produced from Lipase mediated trans-esterification of Algal oil obtained from Botryococcus braunii. Before transesterification, Free Fatty Acid (FFA) content in algal oil was reduced and yield of biodiesel was 68.70%, 92% before and after the reduction of FFA respectively. Since lipase is non-toxic, recyclable, and lipase mediated trans-esterification can be carried out at 350-400 C. Based on these observations lipase mediated trans-esterification is more beneficial than chemical trans-esterification, which can be carried out at 600-65oC.
