An explosion occurred on 13 November 2005, at an aniline production factory of the Jilin Petrochemical Corporation, Jilin Province, China, which led to the world-shaking water pollution accident, in which over 100t of nitrobenzene and related compounds were released into the environment. Large amounts of toxic organic pollutants traversed through the unsaturated zone into the local groundwater system, causing serious groundwater pollution problems and nitrobenzene and aniline were recognized as the dominant organic pollutants through monitoring and analyzing the contaminated groundwater.1 Biodegradation of nitrobenzene, aniline and their pathways have been studied extensively as single contaminants by many researchers. However, no attention has been devoted to the degradation of nitrobenzene and aniline as a mixture. It is desirable and important to study the degradation of both aniline and nitrobenzene in the same system from a practical aspect.
