Potential for bioremediation of xenobiotic compounds by the white-rot fungus Phanerochaete chrysosporium

The white‐rot fungi produce an unusual enzyme system, characterized by a specialized group of peroxidases, that catalyzes the degradation of the complex plant polymer lignin. This ligninolytic system shows a high degree of nonspecificity and oxidizes a very large variety of compounds in addition to...

Description
Summary:The white‐rot fungi produce an unusual enzyme system, characterized by a specialized group of peroxidases, that catalyzes the degradation of the complex plant polymer lignin. This ligninolytic system shows a high degree of nonspecificity and oxidizes a very large variety of compounds in addition to lignin. Among these compounds are numerous environmental pollutants. Thus, the white‐rot fungi show considerable promise as bioremediation agents for use in the restoration of environments contaminated by xenobiotic molecules. One white‐rot fungus, Phanerochaete chrysosporium, has been studied in great detail with regard to ligninolytic enzymes and the degradation of anthropogenic chemicals. It has been widely promoted as a bioremediation agent. This article examines literature concerning the degradation of xenobiotic compounds by Phanerochaete chrysosporium and attempts to critically assess this organism's real potential as a bioremediation tool.
