Research and development for purification of oil-contaminated soil using newly natural fungal isolate having ability for degradation of oil

利用一种具有石油降解能力的新型天然腐木真菌，研究了原油（C重油）污染土壤的净化方法。首次利用该真菌对几种多环芳烃（PAH）进行了生物降解，发现了该真菌对PAH的降解途径。在此基础上，找到了利用真菌净化多环芳烃污染土壤的方法。在此基础上，利用真菌制备的固体介质与一种吸油剂相结合，开发了原油（C重油）污染土壤的净化方法。

Method for purification of crude oil (C heavy oil)-contaminated soil was tried to develop using a newly natural wood-rotting fungal isolate having ability for degradation of petroleum. For the first time, biodegradation of several kinds of PAH (polyaromatic hydrocarbon) with the fungus was conducted and found the degradation pathway of PAH by the fungus. On the basis of the results, the method for purification of PAH-contaminated soil was found by use of the fungus. And furthermore, on the basis of the developed method, the method for purification of crude oil (C heavy oil) -contaminated soil was developed by the combined use of the solid medium prepared from the fungus and a kind of oil absorber.
