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 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 کاملOxidative 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 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...
