Process for producing optically active 1,3-butanediol by asymmetric assimilation

摘要

An optically active 1,3-butanediol can be produced by either (1) treating a mixture of 1,3-butanediol enantiomers with a microorganism, which has been optionally treated, capable of asymmetrically assimilating said mixture, or (2) preparing a microorganism, which has been optionally treated, capable of asymmetrically reducing 4-hydroxy-2-butanone, and collecting optically active 1,3-butanediol.
