Fungi possess vast potential for biodegradation of petroleum hydrocarbons (Harms et al., 2011). The potential of fungi to remove organic pollutants is extended to hazardous metals, metalloids and radionuclides (Atlas, 1981, Harms et al., 2011 and Pinedo-Rivilla et al., 2009). They are known to perform chemical modification and subsequently enhanced bioavailability of pollutants. Other merits of using fungi in biodegradation include mycelia growth and extension, catabolic enzymes with low substrate specificity, and less dependence on pollutants to be utilized as sole growth substrate. In addition, fungi possess different non-specific enzymes that enhance degradation because of their substrate non-specificity. Different enzymes, including cytochrome P450 monooxygenases, laccases, miscellaneous transferases, nitroreductase and peroxidases (Cerniglia and Sutherland, 2010 and Harms et al., 2011), can be used as key indicators of fungal activities in contaminated soil. Fungi can also be used in consortia with bacteria, other fungi and with plants as endo-or-ectomycorrhizal associations for biodegradation of hydrocarbons (Harms et al., 2011).
