Microbiological process for the preparation of heteroaromatic carboxylic acids using microorganisms of the genus Alcaligenes.

摘要

DESCRIBED PROCEEDINGS MICROBIOLOGICAL FOR heteroaromatic carboxylic acids or their physiologically acceptable salts of the general formulas wherein R {sup, 1}, R {SUP, 2} may be identical or different and are a hydrogen atom or halogen, YX A -CH nitrogen atom or. REACTION IS DONE SO THAT IS USED AS SUBSTRATE nitriles heteroaromatic of the general formulas wherein R {SUP, 1}, R {sup 2} x have the meanings given above for the cultivation of microorganisms of the genus Alcaligenes USING 2-cyano-pyridine, who have cultivated BEFORE THE PRESENCE biotransformation dicarboxylic acids, tricarboxylic acids or carbohydrates; They OBTAINED the corresponding carboxylic acids and these are optionally pass their physiologically acceptable salts.
