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 کاملAsiatic brown fruit rot - Monilia polystroma
Monilia polystroma is the conidial form of an unknown apothecial ascomycete closely related to Monilinia fructigena, from which it has so far been distinguished by molecular means. Although M. fructigena and the other brown-rot species, M. fructicola and M. laxa, are known on various continents, Monilia polystroma was identified in Japan and initially known only in that country. A recent publis...
متن کاملProduction and degradation of oxalic Acid by brown rot fungi.
Our results show that all of the brown rot fungi tested produce oxalic acid in liquid as well as in semisolid cultures. Gloeophyllum trabeum, which accumulates the lowest amount of oxalic acid during decay of pine holocellulose, showed the highest polysaccharide-depolymerizing activity. Semisolid cultures inoculated with this fungus rapidly converted C-labeled oxalic acid to CO(2) during cellul...
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....
