Abstract

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 g/l, with a molar recovery yield of 48.4% from a racemate of 15% and an optical purity of 95% ee.
