摘要: 生物修复技术是处理石油污染土壤最简单有效的方法之一。本文在系统概述土壤石油污染的环境危害及多种土壤修复技术的基础上,着重介绍了菌根生物修复技术,论述了菌根真菌对土壤中石油污染物的降解效果,探讨了菌根真菌降解污染物的可能机制:酶作用、根际作用、共代谢作用、基因调控;讨论了石油污染土壤的菌根生物修复前景和发展趋势。

Abstract: Bioremediation is one of the most effective strategies for the remedia tion of petroleum-contaminated soil. This paper summarized the environmental im pacts of soil petroleum contamination, and introduced several remediation techno logies, with the emphasis on mycorrhizal remediation technology. The mechanisms of petroleum biodegradation in soil by mycorrhizal fungi include enzyme catalysi s, mycorrhizosphere, co-metabolism, and genetic control. The perspectiv es in mycorrhizal bioremediation of petroleum-contaminated soil were also discussed.
