The study on the growth characteristics of two ectomycorrhizal fungi Gomphidius viscidus and Laccaria bicolor under 10 g x 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.
对两种外生菌根真菌粘盖牛肝菌和双色蜡蘑在10 g x L(-1)柴油条件下的生长特性及其对柴油的降解效果研究表明，这两种外生菌根真菌均能以柴油作为唯一碳源。培养14天后，双色蜡蘑的降解效果为39.90%，粘盖牛肝菌为31.32%，降解的烃类主要为16C - 22C烯烃。外生菌根真菌降解柴油的能力随培养基成分而异。当以葡萄糖作为第二碳源时，真菌的生物降解能力受到抑制，尽管真菌生物量是未添加葡萄糖时的2 - 5倍。高浓度无机氮在一定程度上可促进降解效果，但促进作用不大。
