Abstract:
A process for the preparation of (R)-1,2-propanediol, comprising: cultivating a microorganism Pseudomonas nitroreducens DS-S-RP8 (Deposit No.: FERM BP-7793) or Alcaligenes sp. DS-S-7G (Deposit No.: FERM BP-3098) which assimilates (S)-1,2-propanediol in a complete synthetic medium containing racemic 1,2-propanediol as a single carbon source, wherein the microorganism stereoselectively assimilates (S)-1,2-propanediol; and then isolating the remaining (R)-1,2-propanediol from the culture broth.
