Nitrobenzene is one of the toxic compounds. Much work had focused on biodegradation of it sofar. Two main pathways for nitrobenzene biodegradation, oxidative and partial reductive pathways, were reviewed in this article. The mechanism of these pathways including involved enzymes and genes was introduce in details. Comparative analysis of the pathways would provide basis for the development and application of biodegradation technology for nitrobenzene and other organic pollutants.
