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.
