Process for stereoselectively hydrolyzing esters or esterifying acids with lipase preparations of Candida rugosa in aqueous/organic systems, where the acid is not substituted at the 2-position with a halogen, e.g. process for the production of R-2-(4-hydroxyphenoxy)propionic acid at high en tiomeric excess. Additionally disclosed is a process for separating and purifying the isozymes from the lipase of Candida rugosa and their use for the stereoselective hydrolysis of esters, transesterification of esters and esterification of acids.
