Biodiesel, one of the alternative fuels, is produced from the transesterification of vegetable or animal oil with alcohol and has become more attractive recently because of its benefits, i.e., it is non-toxic, biodegradable, and renewable. Among various biodiesel production processes, biological process overcomes defect of chemical process such as energy intensive, difficulty of the glycerol and catalyst separating. However, it has not been commercialized because of the high price, the instability of biological catalysts and slow reaction rate. To overcome these
disadvantages of biological process, various processes have been investigated. Therefore, in this talk, current state and development of various biological processes were reviewed for biodiesel production.
