| titleOfInvention | Production of l-lactic acid |
| abstract | PURPOSE: To produce L-lactic acid having high optical purity, by culturing a microbial strain capable of assimilating D-lactic acid in racemic lactic acid or in a mixture of racemic lactic acid and an optically active lactic acid or by contacting the racemic lactic acid, etc., with cultured microorganism. n CONSTITUTION: A microorganism capable of assimilating D-lactic acid and having higher assimilation rate of D-lactic acid than that of L-lactic acid, e.g. Acetobacterium woodii DSM2396 is cultured in the presence of racemic lactic acid or a mixture of racemic lactic acid and optically active lactic acid. The culture is carried out generally e.g. at 3W10pH and 20W60°C for several hours W several days. After removing microbial cells, the cultured liquid is concentrated, subjected to ion exchange treatment, solvent extraction or distillation as a lactic acid ester and the treated product is hydrolyzed to enable the recovery and purification of L-lactic acid. n COPYRIGHT: (C)1988,JPO&Japio |
