摘要：Samples of water from two rivers in Osaka, one of which is considered to be unpolluted and the other moderately polluted by man made chemicals were shown to have different capabilities in the biodegradation of aniline. Microorganisms in the unpolluted Mino River water were not able to biodegrade aniline, whereas those in the moderately polluted Ina River water could do so. The microflora differed significantly in the two rivers. The MPN counts of the aniline degrading microorganisms of these two river waters also indicated less chance of aniline biodegradation in the Mino River. This would suggest that aniline degradation in river waters may reveal many facts on degree of adaptation to and alteration of natural populations under pollutant stress.
