Abstract

Lipases were screened for their ability to transesterify triglycerides with short-chain alcohols to alkyl esters. The lipase fromMucor miehei was most efficient for converting triglycerides to their alkyl esters with primary alcohols, whereas the lipase fromCandida antarctica was most efficient for transesterifying triglycerides with secondary alcohols to give branched alkyl esters. Conditions were established for converting tallow to short-chain alkyl esters at more than 90% conversion. These same conditions also proved effective for transesterfying vegetable oils and high fatty acid-containing feedstocks to their respective alkyl ester derivatives.
