Biodiesel is an alternative fuel for diesel engine that is environmentally acceptable.Conventionally, biodiesel is produced by transesterification of triglycerides and short alcohols in the presence of an acid or an alkaline catalyst.There are several problems associated with this kind of production that can be resolved by read more using lipase as the biocatalyst.The aim of the present work was to investigate novel acyl acceptors for biodiesel production.2-Propanol and n-butanol have a less negative effect on lipase stability, and they also improve low temperature properties of the fuel.
However, excess alcohol leads to inactivation of the enzyme, and glycerol, a major byproduct, can block the immobilized enzyme, resulting in low enzymatic activity.This problem was solved by 7gm pravana using methyl acetate as acyl acceptor.Triacetylglycerol is produced instead of glycerol, and it has no negative effect on the activity of the lipase.
