Fatty acid methyl esters production: chemical process variables
The advantages of fatty acid methyl esters as basic oleochemicals over fatty acids, the seventies world energy crisis and the use of those oleochemicals as fuels, have increased research interest on fats and oils trans-esterification. In this document, a

Specificity of Mucor miehei lipase on methyl ester substrates
Fatty acid methyl esters constitute a good substrate for the characterization of lipase typospecificity. In the present work, the hydrolytic action of lipase from Mucor miehei was studied. It was demonstrated that this lipase preferentially catalyses the
