Enantioselective Production of (S)-3-Hydroxybutyric Acid, (S)-1,3-Butanediol and (R)-1,3-Butanediol Using Methanol Yeast

Abstract

Abstract (S)-3-Hydroxybutyric acid and (S)-1,3-butanediol were obtained by the treatment of 1,3-butanediol with the resting cells of methanol yeast, Candida boidinii (IFO 10574). (R)-1,3-Butanediol was also obtained in high optical purity by the enantioselective reduction of 4-hydroxy-2-butanone in the presence of methanol using the same methanol yeast.
