Abstract: The study on the growth characteristics of two ectomycorrhizal fungi Gomphidius viscidus and Laccaria bicolor under 10 g·L^-1 of diesel and their degradation effect on the diesel showed that both of the ectomycorrhizal fungi could utilize diesel as their only carbon source. After 14day culture, the degradation effect was 39.90% for Laccaria bicolor and 31.32% for Gomphidius viscidus, and the degraded hydrocarbons were mainly 16C-22C alkenes. The capability of the ectomycorrhizal fungi to degrade diesel varied with the components of culture medium. When glucose was used as the second carbon source, the biodegradation capability of the fungi was inhibited, though the fungal biomass was 2-5 times as much as that without glucose addition. High concentration of inorganic nitrogen could promote the degradation effect to a certain extent, but not greatly.
