Polycyclic aromatic hydrocarbons (PAHs) are two or more rings of benzene fused with both natural and anthropogenic sources. PAHs are to a large degree distributed contaminants of environmental that have detrimental biological effects, carcinogenicity toxicity, and mutagenicity. Because of their ubiquitous occurrence, bioaccumulation potential, recalcitrance and carcinogenic activity, the PAHs have compiled significant environmental concern. The PAHs may undergo volatilization, photolysis, adsorption, and chemical degradation. The microbial degradation is the main degradation process, numerous of fungi metabolize PAHs by using enzymes that include laccase, lignin and manganese peroxidase, as wall as cytochrome P450 and epoxide hydrolase. The enzymes of fungi implicated in the PAHs degradation, the fungal lignolytic enzymes are laccase, lignin and manganese peroxidase, those fungi extracellular and stimulate radical formation through oxidation to destabilize bonds in a molecule.In this review explains the biodegradation potential of ligninolytic and non-ligninolytic fungi to PAHs and also shows known conversion pathways.
