A novel enzymatic route for biodiesel production from renewable oils in a solvent-free medium

Yuanyuan Xu et al. Biotechnol Lett. 2003 Aug.

Abstract

A new enzymatic route for biodiesel production from soybean oil was developed using methyl acetate as a novel acyl acceptor. Novozym 435 (immobilized Candida antarctica lipase) gave the highest methyl ester (ME) yield of 92%. The optimum conditions of the transesterification were 30% enzyme based on oil weight; a molar ratio of methyl acetate/oil of 12:1; temperature 40 degrees C and reaction time 10 h. Since no glycerol was produced in the process, this method is very convenient for recycling the catalyst and by-product triacetylglycerol showed no negative effect on the fuel property.
