Abstract

A mutant having a 30-fold increased ability to synthesize pyrrolnitrin was isolated from ATCC 15926 after mutagenesis with -methyl-′-nitro--nitrosoguanidine. The mutant strain also differed from the parent strain in pigmentation and in its inability to catabolize anthranilic acid and the benzene moiety of tryptophan and kynurenine.
