Peroxiredoxins (Prxs) are a ubiquitous family of peroxidases widely distributed among prokaryotes and eukaryotes. Here, we report on the cloning and functional characterization of a cDNA designated PcPrx-1, encoding peroxiredoxin from the white-rot fungus Phanerochaete chrysosporium. The full-length PcPrx-1 cDNA (932 bp) contains an open reading frame of 200 amino acid residues with a molecular...

The white rot fungus, Phanerochaete chrysosporium, is one of the few organisms with documented ability to degrade lignin. Protoplasts from P. chrysosporium were disrupted by osmotic shock and membrane vesicles were isolated from the cell debris. The vesicles exhibit active glucose transport that is consistent with a glucose/H+ symport mechanism. An artificial gradient of H+ (outside greater tha...

The potential of nine fungal strains for pre-treating Eucommia ulmoides Oliver seed shells (EUOSSs) was investigated. Phanerochaete chrysosporium Burds. was found to be the best fungal strain for pretreating EUOSSs. After co-pre-treatment with acetic acid and P. chrysosporium Burds., which was cultivated in a solid state with an approximately 74% moisture content at 28 °C for 28 d, the weight l...

The white rot fungus Phanerochaete chrysosporium metabolized phenanthrene when it was grown for 7 days at 37 degrees C in a medium containing malt extract, D-glucose, D-maltose, yeast extract, and Tween 80. After cultures were grown with [9-14C]phenanthrene, radioactive metabolites were extracted from the medium with ethyl acetate, separated by high-performance liquid chromatography, and detect...

Irgarol 1051 (2-methylthio-4-tert-butylamino-6-cyclopropylamino-s-triazine), a derivative of s-triazine herbicide, is an antifouling compound used as an alternative to organotins. The compound is highly persistent and is known to be biodegraded only by the white rot fungus, Phanerochaete chrysosporium. We used partially purified manganese peroxidase (MnP) prepared from P. chrysosporium to evalu...

The effects of adding the biosurfactant rhamnolipid, the lignolytic and cellulolytic fungus Phanerochete chrysosporium, and the free-living nitrogen-fixing bacterium Azotobacter chrococcum on vermicomposting of green waste with Eisenia fetida was investigated. The addition of rhamnolipid and/or either microorganism alone or in all combinations significantly increased E. fetida growth rate, the ...

The glutathione-S-transferase (GST) proteins represent an extended family involved in detoxification processes. They are divided into various classes with high diversity in various organisms. The Ure2p class is especially expanded in saprophytic fungi compared to other fungi. This class is subdivided into two subclasses named Ure2pA and Ure2pB, which have rapidly diversified among fungal phyla....

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...

Two novel feather-degrading fungi belonging to Chrysosporium and Microsporum genus were isolated from poultry waste in Goa, India. The fungi produced extra cellular keratinolytic enzyme in a feather meal broth using chicken feather as a sole of carbon and nitrogen source. Maximum enzyme activity was obtained within 96 h (150 U/ml and 90 U/ml for Chrysosporium and Microsporum respectively) of cu...
