It was found that 4-nitroquinoline-nitrogen-oxide and 8-hydroxyquinoline acted on Asp. oryzae as mutagenic agents, but the latter compound only when the spores of the mold were beforehand kept at 60℃ for 15 min.The characters of many variants obtained by treating the mold with these chemical agents are summarized as follows : 1) There were several types in the variants obtained by the treatment with 4-nitro-quinoline-nitrogen-oxide, while 8-hydroxyquinoline produced only two kinds of albino and bluish green types.2) In the biochemical points, the variants behaved differently to the nutrient requirements, except the iso-leucineless, phenylalanineless and lysineless strains obtained.The treatment with 8-hydroxyquinoline produced fifteen nitratophobe strains, but 4-nitroquinoline-nitrogen-oxide gave only one strain of the same character.
