Abstract
A process for preparation of S-(+)-3-halogeno-1,2-propanediol which comprises cultivating a bacterium, which has an ability to assimilate R-(-)-3-halogeno-1,2-propanediol and belongs to the genus Alcaligenes, or its culture broth in a medium containing racemate 3-halogeno-1,2-propanediol, and recovering S-(+)-3-halogeno-1,2-propanediol from the resulting culture broth.
Claims7
A process for the preparation of S-(+)3-halogeno-1,2-propanediol which comprises cultivating a bacterium, which has an ability to assimilate R-(-)-3-halogeno-1,2-propanediol and belongs to the genus Alcaligenes and is selected from the group consisting of Alcaligenes sp. DS-S-7G, Alcaligenes sp. DS-S-8S, and Alcaligenes sp. DS-S-1C in a culture medium containing racemate 3-halogeno-1,2-propanediol, and recovering S-(+)-3-halogeno-1,2-propanediol from the resulting culture.
The process of claim 11 wherein the cultivation is carried out at a pH of about 4 to about 9.
