Abstract: Polynuclear-aromatic hydrocarbons are the most important environmental pollutant agents and relatively resistance to degrading. White rot fungi are wood degrading basidiomycetes that not only degrade Lignin but also the vast environmental pollutant. In this research capability of Coriolus versicolor for crude oil and beech wood degradation in the presence of surfactant and wood preservative evaluated. There were high correlation among the increasing mycelium growth and the decreasing wood mass and degrading crude oil that shows high capacity for degradation.
