Abstract
An immobilized isozyme of Lipase MY or AY from Candida rugosa is used for stereoselectively hydrolyzing racemic mixtures of esters of 2-substituted acids, other than 2-halo propionic acids, transesterifying esters or acids or esterify acids or alcohols, at high enantiomeric excess, in an organic solvent. Immobilization of the isozyme may be carried out in the presence of an organic acid such as stearic acid. The immobilized isozyme may be used with a fatty acid or fatty acid ester that increases stereoselectivity or rate of hydrolysis of a mixture of racemic esters.
