Abstract

PURPOSE:To produce pyruvic acid at a low cost, by adding an aminopolycarboxylic acid-type chelating agent to a reaction system for the production of pyruvic acid from L-tartaric acid in the presence of cultured product of microorganism containing L-tartaric acid dehydratase. CONSTITUTION:A microorganism containing L-tartaric acid dehydratase and belonging to Pseudomonas genus, e.g. Pseudomonas putida, Pseudomonas espi, etc., is cultured, and pyruvic acid is produced and accumulated from L-tartaric acid or its salt in the presence of the cultured product or its treated product. The yield of pyruvic acid is improved by adding an aminopolycarboxylic acid- type chelating agent such as ethylenediaminetetraacetic acid, diaminopropanoltetraacetic acid, glycol ether diaminetetraacetic acid, etc., to the reaction system. The pyruvic acid produced and accumulated in the system can be separated by conventional method.

However, this conventional method is a study only on the purified enzyme of L-tartrate dehydratase, and there has been no study using live bacterial cells containing the enzyme, which is industrially advantageous. Moreover, when using monotartaric acid to prepare the enzyme casing according to the conventional method, it was difficult to maintain the activity over a long period of time, and a large amount of bacterial cells were required to terminate the reaction. I didn't have the means. It was also found that the yield of pyruvic acid was significantly reduced because the pyruvic acid produced was biochemically decomposed.
