Biodegradation Mechanism and Technology of Polycyclic Aromatic Hydrocarbons

Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern.PAHs are one of the most prevalent groups of contaminants found in soil.Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie.This paper reviews the existing screening methods of PAH-degrading bacteria.It studied the mechanism and technical applications of the cometabolism in PAHs.Author gives the suggestions and prospects in Biodegradable trend of PHAs.
