Degradation of 2,4-dinitrotoluene by the lignin-degrading fungus Phanerochaete chryssosprorium

Article Abstract:

The reaction mechanism in the degradation of 2,4-dinitrotoulene by Phanerochaete chrysosoporium was elucidated. To construct the metabolic pathway, fungal metabolites and oxidation products produced by manganese peroxidase, lignin peroxidase and crude intracellular cell extracts were characterized. Results showed that the demineralization of 2,4-dinitrotoluene by P. chrysosporium occured only under nitrogen-limiting states which implied that the lignin-degradative system was responsible for the degradation process.

Degradation of azo dyes by the lignin-degrading fungus Phanerochaete chrysosporium

Article Abstract:

Phanerochaete chrysosporium was found to extensively mineralize a wide range of azo dyes under nitrogen-limiting, secondary metabolic conditions. The rate of mineralization was dependent on the type of ring substituent. Mineralization of substituted aromatic rings was greater than for unsubstituted ones. Most dyes were degraded only under nitrogen-limiting, ligninolytic conditions, but some were also degraded under nonligninolytic, nitrogen-sufficient conditions.

Degradation of 2, 4, 5-trichlorophenol by the lignin-degrading basidiomycete Phanerochaete chrysosporium

Article Abstract:

The degradation of the priority pollutant 2,4,5-TCP by Phanerochaete chrysoporium is examined. There is an involvement of purified lignin peroxidase (LiP) and manganese peroxidase (MnP) in the degradative pathway. All three chlorine atoms are removed before ring cleavage occurs.
