The synthesis of (R)-1,3-butanediol (BDO) from its racemate was studied using whole cells of recombinant Escherichia coli expressing an (S)-specific secondary alcohol dehydrogenase (CpSADH) from Candida parapsilosis by enantioselective oxidation. Under the optimized conditions, the yield of (R)-1,3-BDO reached 72.6
