| 摘 要： | 甲烷是一种重要的温室气体,其对全球气候变暖的贡献率约占20%。微生物进行的甲烷厌氧氧化(Anaerobic oxidation of methane,AOM)是减少自然环境中该温室气体排放的重要生物途径。根据耦联反应的不同,可将AOM分为两类,即硫酸盐还原型甲烷厌氧氧化(Sulphate-dependent anaerobic methane oxida-tion,SAMO)和反硝化型甲烷厌氧氧化(Denitrification-dependent anaerobic methane oxidation,DAMO),前者以SO42-作为AOM的最终电子受体,后者以NO2-/NO3-作为AOM的最终电子受体。深入了解这两种类型AOM的发生机理,有助于更好地理解该生物过程的重要性,为AOM工艺的开发提供理论依据。鉴此,本文简要介绍了不同类型的AOM及其参与的微生物,着重阐述了其发生机理,并探讨了AOM未来的研究方向与应用前景。

| Abstract: | Methane is a major greenhouse gas,which contributes estimatedly 20% to global warming.Microbially mediated anaerobic oxidation of methane(AOM) is an important way to reduce methane emission in nature.According to different coupling reactions,AOM can be divided into two types,Sulphate-dependent anaerobic methane oxidation(SAMO)and Denitrification-dependent anaerobic methane oxidation(DAMO).SO2-4 and NO-2/NO-3 function as their terminal electron acceptors,separately.This review summarizes types of AOM and mic... |
