Comparative genomics of Ceriporiopsis subvermispora and Phanerochaete chrysosporium provide insight into selective ligninolysis.
Efficient lignin depolymerization is unique to the wood decay basidiomycetes, collectively referred to as white rot fungi. Phanerochaete chrysosporium simultaneously degrades lignin and cellulose, whereas the closely related species, Ceriporiopsis subvermispora, also depolymerizes lignin but may do so with relatively little cellulose degradation. To investigate the basis for selective ligninoly...
متن کاملIsoenzyme multiplicity and characterization of recombinant manganese peroxidases from Ceriporiopsis subvermispora and Phanerochaete chrysosporium.
We expressed cDNAs coding for manganese peroxidases (MnPs) from the basidiomycetes Ceriporiopsis subvermispora (MnP1) and Phanerochaete chrysosporium (H4) under control of the alpha-amylase promoter from Aspergillus oryzae in Aspergillus nidulans. The recombinant proteins (rMnP1 and rH4) were expressed at similar levels and had molecular masses, both before and after deglycosylation, that were ...
متن کاملLigninase of Phanerochaete chrysosporium
This study examined the ligninase-catalysed degradation of lignin model compounds representing the arylglycerol ,-aryl ether substructure, which is the dominant one in the lignin polymer. Three dimeric model compounds were used, all methoxylated in the 3and 4-positions of the arylglycerol ring (ring A) and having various substituents in the ,-ether-linked aromatic ring (ring B), so that competi...
متن کاملSelective Medium for Isolating Phanerochaete chrysosporium from Soil.
A selective medium was developed that is capable of isolating Phanerochaete chrysosporium from soil. This medium contains 15 ppm of benomyl (15 mug g) and 550 ppm of streptomycin sulfate in 2% malt agar and is held at 39 degrees C after inoculation. P. chrysosporium was isolated from three nonsterile forest soils to which the fungus had been added. These soils contained large microbial populati...
متن کاملModeling Based Structural Insights into Biodegradation of the Herbicide Diuron by Laccase-1 from Ceriporiopsis subvermispora
The herbicide diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea) is used in many agricultural crops and non-crop areas worldwide, leading to the pollution of the aquatic environment by soil leaching. White rot fungi and its lignin modifying enzymes, peroxidases and laccases, are responsible for its degradation. Therefore, it is of interest to explore the potential use of Ceriporiopsis subvermispo...
