Production of Ligninases and Degradation of Lignin in Agitated Submerged Cultures of Phanerochaete chrysosporium.
Research on the extracellular hemeprotein ligninases of Phanerochaete chrysosporium has been hampered by the necessity to produce them in stationary culture. This investigation examined the effects of detergents on development of ligninase activity in agitated submerged cultures. Results show that addition of Tween 80, Tween 20, or 3-[(3-colamidopropyl)dimethylammonio]1-propanesulfonate to the ...
متن کاملExtracellular oxidative systems of the lignin-degrading Basidiomycete Phanerochaete chrysosporium.
The US Department of Energy has assembled a high quality draft genome of Phanerochaete chrysosporium, a white rot Basidiomycete capable of completely degrading all major components of plant cell walls including cellulose, hemicellulose and lignin. Hundreds of sequences are predicted to encode extracellular enzymes including an impressive number of oxidative enzymes potentially involved in ligno...
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 کاملA novel extracellular multicopper oxidase from Phanerochaete chrysosporium with ferroxidase activity.
Lignin degradation by the white rot basidiomycete Phanerochaete chrysosporium involves various extracellular oxidative enzymes, including lignin peroxidase, manganese peroxidase, and a peroxide-generating enzyme, glyoxal oxidase. Recent studies have suggested that laccases also may be produced by this fungus, but these conclusions have been controversial. We identified four sequences related to...
متن کاملXylanase Activity of Phanerochaete chrysosporium.
Xylan-degrading enzymes were induced when Phanerochaete chrysosporium was grown at 30 degrees C in shake flask media containing xylan, Avicel PH 102, or ground corn stalks. The highest xylanase activity was produced in the corn stalk medium, while the xylan-based fermentation resulted in the lowest induction. Analytical and preparative isoelectric focusing were used to characterize xylanase mul...
