The depleted supplies of fossil fuels have led to an increasing commercial interest in renewable fuels. Microalgae have been identified as promising feedstocks for industrial–scale production of renewable biodiesel,due to their high biomass productivity,rapid lipid accumulation, and ability to survive in a small region. Microalgae also contain other active compounds such as DHA、EPA、GLA、polysaccharide and pigments. This review summaries the principles and technology involved in application of supercritical fluid using in microalgae bioenergy production and other valuable microalgae products. We focus on reaction mechanism,the influence of operation conditions, extraction yields under optimal conditions. The study also demonstrated the advantages and developing tendency in application of supercritical fluid technology.
