%X Seven species of ectomycorrhizal fungi, i.e. Boletus edulis, Gomphidius viscidus, Laccaria bicolor, Leccinum scabrum, Xerocomus chrysenteron, Heboloma crustuliniforme and Hebeloma longicaudum, were grown in media with different substrate concentrations of pentachlorophenol (PCP) to determine its effect on fungal growth. Due to their high potential for PCP degradation, Gomphidius viscidus, Laccaria bicolor and Leccinum scabrum may find future application in bioremediation of soils polluted by PCP. The mycelium biomass of these three ectomycorrhizal fungi were measured at different PCP concentrations and their enzymatic activity was assessed by spot tests. No impact on the growth of the mycelia was observed at low ambient PCP levels (less than or equal to 10 mg·L-1), however, at 15 mg·L-1, fungi growth was inhibited. Gomphidius viscidus had redoxases with the highest activity and largest diversity. The high activities of its polyphenol oxidases, laccase and peroxidase, even at high ambient PCP levels, makes Gomphidius viscidus the most promising fungus for bioremediation of PCP contaminated soil.
