摘　　要：BTEX是苯、甲苯、乙苯和二甲苯的统称,存在于原油和石油产品中,其作为化工原料,广泛应用于农药、塑料及合成纤维等制造业。BTEX已成为地下水中普遍存在的污染物,自然衰减或生物修复工程已成功应用于地下水中BTEX的去除。自然衰减受BTEX污染的地下水具有良好的效果,但相比之下,生物修复工程更快、更有效。综述了在好氧和厌氧条件下,地下水中BTEX原位生物修复过程的微生物降解机制。BTEX （acronym of benzene, toluene, ethylbenzene, and xylenes） was wildly found in groundwater. In-situ bioremediation under natural attenuation or enhanced remediation conditions had been successfully used for removal of BTEX from groundwater. Base on the comprehensive literature review, the paper introduced various micro- organisms for BTEX biodegradation, summarized two pathway of BTEX degradation by aerobic microorganisms and anaerobic microorganisms. Some international researches on applications of in situ bioremediation for BTEX were also reviewed which indicated that intrinsic bioremediation can reduce BTEX contaminated water. However, engineering bioremediation was faster and more efficient.
