With the increased demand for petroleum and petroleum products from all parts of the society, environmental pollution caused by petroleum development and production processes is becoming increasingly serious. Soil pollution caused by petroleum seriously affects environmental quality in addition to human lives and productivity. At present, petroleum in soil is mainly degraded by biological methods. In their natural state, native bacteria in the soil spontaneously degrade petroleum pollutants that enter the soil; however, when the pollution levels increase, the degradation rates decrease, and it is necessary to add nutrients, dissolved oxygen, biosurfactants and other additives to improve the degradation ability of the native bacteria in the soil. The degradation process can also be enhanced by adding exogenous petroleum-degrading bacteria, microbial immobilization technologies, and microbial fuel cell technologies.

土壤中石油生物降解性的研究进展

随着社会各阶层对石油和石油产品的需求增加，由石油开发和生产过程引起的环境污染变得越来越严重。石油引起的土壤污染不仅会严重影响人类生活和生产力，还会影响环境质量。目前，土壤中的石油主要通过生物方法降解。在自然状态下，土壤中的天然细菌会自发降解进入土壤的石油污染物。但是，当污染水平增加时，降解速率降低，必须添加营养素，溶解氧，生物表面活性剂和其他添加剂，以提高土壤中天然细菌的降解能力。通过添加外源石油降解细菌，还可以增强降解过程，
