PURPOSE:To prepare the titled compound useful as a raw material for the production of amino acids, in high yield, by adding and reacting an indole compound to a reaction system producing pyruvic acid from tartaric acid in the presence of cultured product of microoganism capable of converting L-tartaric acid to pyruvic acid. CONSTITUTION:The objective compound can be prepared efficiently, by adding and reacting indole and/or its derivative to a reaction system to produce pyruvic acid from tartaric acid and/or its salt in the presence of cultured product (or its treated product) of a microbial strain (e.g. Pseudomanas putida ATCC 17642) capable of converting L-tartaric acid to pyruvic acid. The indole and its derivative is e.g. indole, 5-hydroxyindole, 5-methoxyindole, 5'-chloroindole, etc. |
