    摘要: An industrial and economical method for obtaining a (S)-3-halogeno-1,2-propanediol, which comprises cultivating a microorganism belonging to the genus Pseudomonas which has an ability to assimilate (R)-3-halogeno-1,2-propanediol and can grow by assimilating (R)-3-halogeno-1,2-propanediol as a single carbon source, in a culture medium containing a racemic 3-halogeno-1,2-propanediol as a substrate, and isolating the (S)-3-halogeno-1,2-propanediol from the culture medium.

    摘要: A process for preparation of R-(-)-3-halogeno-1,2-propanediol which comprises cultivating in a medium containing racemate 3-halogeno-1,2-propanediol a bacterium, which, when cultivated in a medium containing racemate 3-halogeno-1,2-propanediol as a sole carbon source, can grow and proliferate, has an ability to assimilate S-(+)-3-halogeno-1,2-propanediol preferentially compared to R-(-)-3-halogeno-1,2-propanediol and belongs to the genus Pseudomonas , ot its culture cells; and recovering R-(-)-3-halogeno-1,2-propanediol from the resulting culture broth.
