Abstract

PURPOSE: A bacterium belonging to Corynebacterium, which is capable of producing L-argininosuccinic acid, is cultured and the medium is subjected to extraction, thus producing industrially and inexpensively L-argininosuccinic acid that is important as the starting material for L-arginine.
CONSTITUTION: A bacterium belonging to Corynebacterium and being capable of producing L-argininosuccinic acid, such as Corynebacterium glutamicum KY-9022 (FERM-4389: L-arginine-requiring mutant) is aerobically cultured in an enriched medium at a pH of 4W9, a temperature of 20W40°C for 1W5 days and a large amount of L-argininosuccinic acid is accumulated in the medium. The product is separated and isolated by an adequate combination of ion-exchange resin method, barium precipitation, alcohol precipitation, etc.
