8196 microorganism of penicillium chrysogenum cubic centimetre of the high bacterial strain of productivity

摘要

A kind of microbial strains penicillium chrysogenum CCM 8196 (NMG FOK 15) that productivity is high. The bacterial strain and obtain mutant by exposure generate spore to chemical mutagen and increased concentration phenylacetic acid in deep drainpipe. Subsequent passive selection result produces 35 in strain penicillium chrysogenum CCM 8196 (NMG FOK 15),At 25 degrees Celsius in the above aeration of cultivation in the G/ml in168 hours flasks of 000 IU PEN.
