Abstract:

Oil pollution in soil caused by the oil extraction wastewater and oil-contained solid wastes is becoming serious. Bioremediation by microorganisms characterized by being environmental-friendly and low cost is widely applied all over the woad. Bioremediation is an application of microbial functions of the oil-polluted soil microbial community. By analyzing and manipulating the oil polluted soil microbial community structure purposely, its functions of egrading petroleum hydrocarbon could be strengthened for effective microbial oil-polluted soil bioremediation.

Key words: oil-contaminated soil , bioremediation , culture-free technology , increasing microbial culturability

摘要：

采油废水和含油固体废弃物的排放,在一些区域造成了严重的土壤石油污染.经济而无二次污染的微生物石油污染土壤治理技术具有难以比拟的优势,其实质是通过对石油污染土壤微生物群落进行定向调控,充分发挥功能微生物的石油污染治理作用,强化对石油烃类污染物质的转化,从而达到石油污染治理和污染土壤修复的目的.
