Microbial remediation techniques for petroleum hydrocarbons contaminated soil: a review

Soil contaminated by petroleum hydrocarbons has attracted great attention. Petroleum hydrocarbons have characteristics of high-toxicity and persistence, thereby severely threatening ecological environment and human health. This review summarized the recent research progress of remediation techniques for petroleum hydrocarbons contaminated soil, and the research status of microbial methods were systematically reviewed. The mechanisms and application prospect of microbially-mediated combined remediation techniques were critically discussed, including plant-microbial, electro-driven, surfactant-enhanced, chemical-oxidation, and animal-microbial remediation. Finally, the future research directions for microbial remediation of petroleum hydrocarbons contaminated soil were suggested.
