Abstract: | The substrate selectivity of several microbial lipases has been examined in the esterification of oleic acid, linoleic acid, linolenic acid and their all-trans-isomers and in the alcoholysis of isomeric linoleic acid methyl esters with n-butanol. Lipases from Candida cylindracea and Mucor miehei preferred fatty acids and methyl esters with a (first) cis double bond in 9-position, while Chirazyme L-5, a Candida antarctica lipase A, had a preference for trans-9 unsaturated substrates. |
