Process for preparation of (R)-1,2-propanediol by microbes

摘要

A process for preparation of (R)-1,2-propanediol which comprises cultivating a microorganism belonging to genus Pseudomonas or genus Alcaligenes which has ability to assimilate (S)-1,2-propanediol as a single carbon source, in a culture medium containing racemic 1,2-propanediol as a single carbon source and then isolating the remaining (R)-1,2-propanediol from the culture broth.
