Abstract
It is possible to efficiently obtain D-(31)-tartaric acid in high yield and to supply DL-tartaric acid of high concentration to the culture medium by cultivating a microorganism which belongs to the genus Pseudomonas, Cryptococcus, Tricosporon or Klebsiella and has an ability to assimilate L-(+)-tartaric acid and does not assimilate substantially D-(-)-tartaric acid in a culture medium containing DL-tartaric acid.

A process for producing D-(-)-tartaric acid characterized by cultivating a microorganism which belongs to the genus Pseudomonas putida, or Tricosporon, and has an ability to assimilate L-(+)-tartaric acid and does not assimilate substantially D-(-)-tartaric acid, decomposing asymmetrically thereby L-(+)-tartaric acid and separating and obtaining remaining D-(-)-tartaric acid from the culture broth.
