Abstract
During the enzyme-catalyzed deacylation of O-acylated mandelates with an alcohol, Chromobacterium viscosum lipase was found to catalyze the transesterifications not only at the hydroxy site but also at the carboxyl site of mandelic acids, while such a side-reaction at the carboxyl site was negligible with the other lipases examined.
