Abstract

PURPOSE:To efficiently obtain pyruvic acid by a fermentation method, by cultivating a microorganism, belonging to the genus Torulopsis and having resistance to aminohydroxyacetic acid and the ability to produce pyruvic acid in a nutrient culture medium. CONSTITUTION:Torulopsis.glabrata TR-2026 (FERM BP-1425) as a parent strain is subjected to variation induction to provide an aminohydroxyacetic acid- tolerant strain AOA-8 (FERM BP-1427), which is then cultivated in a culture medium containing a carbon source, nitrogen source, inorganic salts, vitamins, etc., at pH3-7 and 22-32 deg.C to provide a culture fluid. The aimed pyruvic acid is obtained from the resultant culture fluid by a method for extracting with acidic ether, forming a phenylhydrazone, precipitating and isolating the formed phenylhydrazone, etc.
