Abstract

Optically active 2-hydroxy-4-phenyl-3-butenoic acid can be obtained by treating 2-oxo-4-phenyl-3-butenoic acid with an optionally treated microorganism capable of asymmetrically reducing the 2-oxo-4-phenyl-3-butenoic acid into (R)-2-hydroxy-4-phenyl-3-butenoic acid or (S)-2-hydroxy-4-phenyl-3-butenoic acid to thereby asymmetrically reduce the same into (R)-2-hydroxy-4-phenyl-3-butenoic acid or (S)-2-hydroxy-4-phenyl-3-butenoic acid.
