METHOD OF PRODUCING NITROGEN-CONTAINING HETEROCYCLIC CARBOXYLIC ACIDS CONTAINING HYDROXYL GROUP OR THEIR SOLUBLE SALTS, STRAIN OF BACTERIUM FOR METABOLISM OF NITROGEN-CONTAINING HETEROCYCLIC CARBOXYLIC ACIDS TO HYDROXYL GROUP-CONTAINING NITROGEN-CONTAINING HETEROCYCLIC CARBOXYLIC ACIDS Russian patent published in 1998 - IPC

FIELD: microbiology, biotechnology, organic chemistry. SUBSTANCE: invention relates to a new microbiological method of producing hydroxy-nitrogen-containing heterocyclic carboxylic acids and their soluble salts of the general formula (I) given in description. Method is based on the corresponding nitrogen-containing heterocyclic carboxylic acids and a new strain of microorganism used in this process. Method provides ecologically pure and nonlaborious producing the indicated compounds. New strain of microorganisms Ki 101 (DSM 6920) is used for metabolism of the corresponding above indicated acids to nitrogen-containing heterocyclic carboxylic acids that contain hydroxyl group. The yield is up to 72%. EFFECT: strain indicated above, improved method of producing, increased yield. 6 cl, 2 tbl, 2 ex
