Decay mechanisms of brown-rot fungi
Brown-rot fungi, e.g. the dryrot fungus (Serpula lacrymans), are the most harmful microorganisms in wood in service in Finland and in temperate regions. Brownrot fungi cause wood decay primarly by attacking the carbohydrates of the cell walls, leaving lignin essentially undigested. At the initial stage of the decay, the brown-rot fungi seem to operate by a mechanism which cause extensive change...
متن کاملChanges in Molecular Size Distribution of Cellulose during Attack by White Rot and Brown Rot Fungi.
The kinetics of cotton cellulose depolymerization by the brown rot fungus Postia placenta and the white rot fungus Phanerochaete chrysosporium were investigated with solid-state cultures. The degree of polymerization (DP; the average number of glucosyl residues per cellulose molecule) of cellulose removed from soil-block cultures during degradation by P. placenta was first determined viscosimet...
متن کاملExtensive sampling of basidiomycete genomes demonstrates inadequacy of the white-rot/brown-rot paradigm for wood decay fungi.
Basidiomycota (basidiomycetes) make up 32% of the described fungi and include most wood-decaying species, as well as pathogens and mutualistic symbionts. Wood-decaying basidiomycetes have typically been classified as either white rot or brown rot, based on the ability (in white rot only) to degrade lignin along with cellulose and hemicellulose. Prior genomic comparisons suggested that the two d...
متن کاملInfluence of Carbon Source on Cellulase Activity of White-rot and Brown-rot Fungi
Three white-rot fungi, Polyporus versicolor, Ganoderma applanatum, and Peniopbora “G,” produce an adaptive cellulase complex that can degrade both soluble cellulose (Cx) and microcrystalline cellulose (C1), a highly ordered form of cellulose. Production of Cx and C1 by the white-rot fungi was repressed by simple sugars. Cellualase preparations from three brown-rot fungi, Poria monticola, Lentin...
متن کاملWood Decay by Brown-Rot Fungi: Changes in Pore Structure and Cell Wall Volume
Sweetgum (Liquidambar styraciflua L.) wood blocks were decayed by Postia (= Poria) placenta in soilblock cultures. Decay was terminated at various weight losses, and the pore volumes available to four low molecular weight molecules, (water, 4 Å,; glucose, 8 Å,; maltose, 10 Å; and raffinose, 128,) and three dextrans (Mr 6,000, 38 Å; 11,200, 51 Å; and 17,500, 61 Å) were determined by the solute e...
