摘要：The present study was done to characterize the diversity of the aniline-degrading bacteria in river water in respect to taxonomy, substrate specificity of aniline derivatives, and inducibility and stability of the aniline-degrading activity. Aniline-degrading bacteria, isolated from Ina River water, were shown to belong to the genera Pseudomonas and Alcaligenes, the former being more capable of degrading a wide variety of aniline derivatives than the latter. Aniline-degrading activities of both genera were inducible by aniline and the activities were lost in some strains after treatment with acridine orange, suggesting that the aniline-degrading enzymes were encoded in the plasmid DNA in these strains.
