ABSTRACT:
The present invention provides a method of the production of (S)-.gamma.-halogenated-.beta.-hydroxybutyric acid esters at a high accumulation and a high yield. A microorganism belonging to the genus Stemphylium, Alternaria, Corynespora or Torulaspora is used to asymmetrically reduce a .gamma.-halogenated-acetoacetic acid ester into an (S)-.gamma.-halogenated-.beta.-hydroxybutyric acid ester, and the (S)-.gamma.-halogenated-.beta.-hydroxybutyric acid ester produced is recovered from the reaction mixture.
