White rot fungi efficiently degrade lignin, a complex aromatic polymer in wood that is among the most abundant natural materials on earth. These fungi use extracellular oxidative enzymes that are also able to transform related aromatic compounds found in explosive contaminants, pesticides and toxic…

Mushroom-producing white-rot basidiomycetes can grow rapidly and produce heavy mycelial growth on treated conifer wastes with extractive-degrading fungi. This study evaluates the treatment of scaled-up conifer wood chips with Ophiostoma piliferum (Cartapip 97). Treated conifer chips were used as…

A peroxidase-encoding gene, mnp2, and its corresponding cDNA were characterized from the white-rot basidiomycete Trametes versicolor PRL 572. We used quantitative reverse transcriptase-mediated PCR to identify mnp2 transcripts in nutrient-limited stationary cultures. Although mnp2 lacks upstream…

Treating wood with the water-borne sodium salt of N'-N-naphthaloylhydroxylamine (Na-NHA) protects wood against decay and termite damage. Initial testing indicated little or no inhibition of sapstain fungi, molds, or soft-rot fungi by Na-NHA, suggesting that the mechanism by which this compound…

Wood can be chemically modified to reduce the moisture content of the cell wall and increases decay resistance. As the level of bonded chemical increases, the cell wall equilibrium moisture content decreases and the resistance to attack by white-and brown-rot fungi increases. There is a direct…

Wood inhabiting, rotting and/or decomposing fungi from Alaska include representatives from an assortment of fungal groups (cup, jelly, pored coral, tooth, puffball, gilled and lichenized fungi) and one fungus-like group (the slime molds). Of the more than 1,500 species recorded for North America,…

For most markets for wood, it is used without any treatments or modifications. When wood is used in adverse environments, it may be treated with chemicals to help prevent decay, improve water resistance, reduce the effects of ultraviolet radiation or increase fire retardancy. Many of these…

Eight species of Phanerochaete are reported from Uruguay for the first time, including a new species, P. vesiculosa. Phanerochaete vesiculosa is characterized by thin-walled, clavate to cylindrical vesicles embedded in the subiculum. A key to the known species of Phanerochaete from Uruguay is…

The white-rot basidiomycete Phanerochaete chrysosporium employs extracellular enzymes to completely degrade the major polymers of wood: cellulose, hemicellulose, and lignin. Analysis of a total of 10,048 v2.1 gene models predicts 769 secreted proteins, a substantial increase over the 268 models…

We describe the structure, organization, and transcriptional impact of repetitive elements within the lignin-degrading basidiomycete, Phanerochaete chrysosporium. Searches of the P. chrysosporium genome revealed five copies of pce1, a 1,750-nt non-autonomous, class II element. Alleles encoding a…
