Oxidative Degradation of Wood by Brown-Rot Fungi
Brown-rot fungi are Basidiomycetes that remove cellulose and other polysaccharides from wood, leaving an amorphous, brown, crumbly residue that is composed largely of lignin, hence the name brown-rot. Decay by brown-rot fungi is by far the most serious type of damage to wood in-service. These fungi cause structural failure before losses in total wood substance are detected. The effect of brown-...
متن کاملPectin degradation during colonization of wood by brown-rot fungi
Brown-rot decay results in rapid reduction in degree of polymerization of holocellulose, with concomitant strength loss without removing lignin. Development of new methods of wood protection will require focusing on early events in the sequence of fungal attack during colonization. Pit membranes (sapwood) of wood cell walls represent a readily available source of nonlignified carbohydrate, i.e....
متن کاملMechanisms of degradation by white rot fungi.
White rot fungi use a variety of mechanisms to accomplish the complete degradation of lignin and a wide variety of environmental pollutants. Both oxidative and reductive reactions are required for the metabolism of both lignin and environmental pollutants. The fungi secrete a family of peroxidases to catalyze both direct and indirect oxidation of chemicals. The peroxidases can also catalyze red...
متن کامل9 Enzymology and Molecular Genetics of Wood Degradation by White-Rot Fungi
Our purpose in this chapter is to provide an overview of the enzymology and associated molecular genetics of wood decay by white-rot fungi. These fungi are able to fragment the major structural polymers of wood and other lignocellulosics-lignin, cellulose, and hemicelluloses—and to further metabolize the fragments. The whiterot fungi and related litter-degrading fungi are perhaps nature’s major...
متن کاملEnzyme production by wood-rot and soft-rot fungi cultivated on corn fiber followed by simultaneous saccharification and fermentation.
This research aims at developing a biorefinery platform to convert lignocellulosic corn fiber into fermentable sugars at a moderate temperature (37 °C) with minimal use of chemicals. White-rot (Phanerochaete chrysosporium), brown-rot (Gloeophyllum trabeum), and soft-rot (Trichoderma reesei) fungi were used for in situ enzyme production to hydrolyze cellulosic and hemicellulosic components of co...
