From the literatures, the efficiency of the enzymatic transesterifiaction of triglycerides with methanol (methanolysis) was low compared to that of ethanol in systems without a solvent.
also foundthat in the conversion of palm kernel oil to alkyl esters using Pseu-domonas cepacia lipase, ethanol gave the highest conversion, i.e.,72%, whereas the methyl ester yield from methanol was only 15%.However, ethanol is still used not as often as methanol because ofits higher cost.
