摘　　要：Corynebacterium diphtheria PW8-weissensee was grown on different mediafor screening high toxin produce. Through six times of screening (selecting butyrousbrilliant smooth small colonies and teshng their toxin production capacity) fromoriginal strain producing toxin l60Lf/ ml, a high toxin- producing descendandculture was obtained, which produced 79% more toxin than the original strain did.Corynebacterium diphtheria PW8-weissensee was grown on different mediafor screening high toxin produce.
