ABSTRACT
Mycoremediation is a cleanup technique within the larger field of bioremediation. In this literature
review, the history, species and methods of mycoremediation are investigated.
The literature suggests that many fungi have the ability to degrade a wide
variety of pollutants. The functional group
white-rot fungi have previously been
shown to biodegrade petroleum using extracellular enzymes, and have received much popular
attention. For this reason, the white-rot basidiomycete Pleurotus ostreatus is the focus of this review. The extracellular enzymes that make
mycoremediation possible, fungi’s synergy with bacteria, and the effects of
temperature are discussed. The authors compare mycoremediation to other bioremediation
methods. The authors
conclude that environmental factors such as aeration, soil structure, nutrient
level and especially temperature, may have stronger effects on petroleum loss
than inoculation with white-rot fungi. For volatile
pollutants such as diesel, the use of fungal inoculation may be economical only
when fungal spawn compost is abundantly available. Composting also may be an
inexpensive method to increase temperature, enhancing remediation of
hydrocarbons.
