A Review on Microalgae Based Biofuels

In the present day scenario of soaring oil prices, depleting oil reserves and increasing global warming, biofuels present a renewable and alternative source for energy requirements. It is reported that biofuel produced from microalgae provides better yield among other sources like soybean, jatropha, corn etc. CO2 fixation and bioremediation by removal of several inorganic compounds from waste water are additional benefits. Faster growth rate and ability to grow in harsh conditions and waste land makes microalgae more interesting for biofuel production. This paper presents a review on various microalgae species that can be used for production of biofuels, methods of cultivation, harvesting techniques, lipids extraction technologies from algae biomass and catalytic conversion of lipids into biofuel.
