title: Mycelium growth and degradation of creosote-treated wood by basydiomycetes.
abstract: Tolerance of wood decay fungi of the genera Agrocybe, Armillaria, Auricularia, Daedalea, Pleurotus, Trametes to the presence of various amounts of creosote-treated wood (CTW) in the growth medium was compared. In the case of the most tolerant strain, Pleurotus ostreatus SMR 684, extracellular laccase and peroxidase specific activities were monitored during growth in the presence of CTW. Degradation of various creosote-constituting polycyclic aromatic hydrocarbons by this strain was evaluated by GC-MS and the ecotoxicity of treated and untreated CTW was compared by Microtox test.
