Specificity of Mucor miehei lipase on methyl ester substrates

open access: yesGrasas y Aceites, 1993
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
