RESUMO

Nishida, Shoki (Kanazawa University, Kanazawa, Japan), and Gizo Nakagawara. Relationship between toxigenicity and sporulating potency of Clostridium novyi. J. Bacteriol. 89:993–995. 1965.—The less toxigenic the strains, the stronger was the sporulating potency of Clostridium novyi strains isolated. This was confirmed by investigation of the toxigenicity of substrains of C. novyi 140 possessing different degrees of sporulating potency. Atoxic strains or type C strains could be obtained from the parent type A strain (no. 140) by heat selection. This phenomenon was also observed in the other five strains. Prolonged storage of C. novyi strains also resulted in selection of cells with stronger sporulating ability and lower toxigenicity.
