Evaluation of fungal capacity for detoxification of extractives in Scots pine sapwood
Ninety wood-inhabiting fungi were screened for their ability to degrade and detoxify acetone extractives in Scots pine (Pinus sylvestris L.) sapwood under solid-state fermentation conditions.

Summary: | Ninety wood-inhabiting fungi were screened for their ability to degrade and detoxify acetone extractives in Scots pine (Pinus sylvestris L.) sapwood under solid-state fermentation conditions. Fungal degradation of resin acids and long-chain fatty acids was investigated by high pressure liquid chromatography with evaporative light scattering detection (HPLC-ELSD) and the toxicity of the acetone soluble fraction of wood measured by Microtox assay. Discriminant analysis of data showed different patterns of extractive detoxification for white-rot basidiomycetes and sapstain fungi. The major detoxification skills of basidiomycetes appeared to be related to the highest degradation of resin acids, and particularly dehydroabietic acid. Among them, Ischnoderma benzoinum, Stereum sanguinolentum and Trametes versicolor greatly reduced the sapwood toxicity due to acetone extractives from the EC
