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, or its culture cells; and recovering R-(-)-3-halogeno-1,2-propanediol from the resulting culture broth.
