Informed strain improvement for lignin degradation by Phanerochaete chrysosporium.
The effect of breeding from the white rot fungus Phanerochaete chrysosporium ME446 on performance for lignin mineralization was examined. This model for informed strain improvement without mutagenesis is based on abundant restriction fragment length polymorphisms (RFLPs). Under optimized conditions for lignin mineralization, extracellular manganese peroxidase (MnP) but not lignin peroxidase (Li...
متن کاملDegradation of Phenol Derivatives by a Phanerochaete Chrysosporium Strain
The white rot fungus Phanerochaete chrysosporium has significant pollutant-degrading capabilities with its oxidoreductases. The lignin-degrading enzyme system of this fungus also allows the breakdown of different organic pollutants (xenobiotics). The most significant enzymes in these processes are the lignin peroxidase and the manganese peroxidase. In this study, Phanerochaete chrysosporium str...
متن کاملDegradation kinetics of pentachlorophenol by Phanerochaete chrysosporium.
The extracellular enzymes and cell mass from the pregrown Phanerochaete chrysosporium cultures were used for the degradation of PCP. The use of both extracellular enzymes and cell mass resulted in extensive mineralization of PCP, while the action of only the crude extracellular enzymes led to the formation of a degradation intermediate (TCHD). A kinetic model, which describes the relationship a...
متن کاملBiochemistry of the oxidation of lignin by Phanerochaete chrysosporium.
The objective of this research was to identify the biochemical agents responsible for the oxidative degradation of lignin by the white-rot fungus Phanerochaete chrysosporium. We examined the hypothesis that activated oxygen species are involved, and we also sought the agent in ligninolytic cultures responsible for a specific oxidative degradative reaction in substructure model compounds. Result...
متن کاملDegradation of 2,4-dichlorophenol by the lignin-degrading fungus Phanerochaete chrysosporium.
Under secondary metabolic conditions the white rot basidiomycete Phanerochaete chrysosporium mineralizes 2,4-dichlorophenol (I). The pathway for the degradation of 2,4-dichlorophenol (I) was elucidated by the characterization of fungal metabolites and of oxidation products generated by purified lignin peroxidase and manganese peroxidase. The multistep pathway involves the oxidative dechlorinati...
