Abstract
There is disclosed a process for preparing optically active 3-phenylglycidic acid ester compound, which comprises permitting a culture broth, cells or treated cells of a microorganism having an ability of stereoselectively hydrolyzing a (2R, 3S)-3-phenylglycidic acid ester compound to act on a racemic 3-phenylglycidic acid ester compound which may also have a substituent on the phenyl group, thereby hydrolyzing the (2R, 3S) optically active isomer and separating and collecting the (2S, 3R) antipode from the reaction mixture.
