摘要：

Widespread environmental pollution by polycyclic aromatic hydrocarbons (PAHs) poses an immense risk to the environment. Bacteria-mediated attenuation has a great potential for the restoration of PAH-contaminated environment in an ecologically accepted manner. Bacterial degradation of PAHs has been extensively studied and mining of biodiversity is ever expanding the biodegradative potentials with intelligent manipulation of catabolic genes and adaptive evolution to generate multiple catabolic pathways. The present review of bacterial degradation of low-molecular-weight (LMW) PAHs describes the current knowledge about the diverse metabolic pathways depicting novel metabolites, enzyme-substrate/metabolite relationships, the role of oxygenases and their distribution in phylogenetically diverse bacterial species.</.
