Summary

From different samples of soil seventeen strains were isolated which grew aerobically in mineral salts medium with quinaldic acid as sole carbon source. Mutants were induced with N-methyl-N′-nitro-N-nitrosoguanidine. One mutant could be isolated which accumulated a yellow compound. The properties of this purified compound were those expected for 2-oxo-3-(4′-hydroxy-2′-oxo-3′,4′-en-butyrate)-pyridine-6-carboxylic acid.
