| 摘 要： | 近十多年来国外研究者对单环芳烃苯系物(主要包括苯、甲苯、乙苯及二甲苯,合称为BTEX)的微生物厌氧降解研究做了大量工作,发现BTEX在NO3-,Mn4+,Fe3+,SO42-,CO2等电子受体条件下能够进行降解,已陆续分离到许多BTEX厌氧降解菌,并对其相应降解酶的生化性质进行了鉴定,相关的基因被克隆、鉴定和改造.通过对BTEX化合物的厌氧生物降解过程、代谢机制与途径、参与降解的主要微生物、相关降解酶及基因等进行综述与分析,提出了BTEX污染物厌氧降解研究中尚需进一步研究的问题.

| Abstract: | Significant research has been done in the past ten years towards understanding of anaerobic biodegradability of monoaromatic hydrocarbons(benzene,toluene,ethlybenzene and xylenes,BTEX).These compounds have been shown to be degraded with nitrate,manganese,ferric iron,sulfate,or carbon dioxide as the sole electron acceptor.Microorganisms capable of degrading BTEX have been isolated,enzymes characterized,and various BTEX degrading genes cloned.In this paper,anaerobic biodegradation,metabolic mechanism and path... |
