【摘要】 甲烷是一种温室气体,其引起的温室效应是CO2的20倍。微生物通过甲烷厌氧氧化(AOM)可以减少自然环境中该温室气体的排放,对缓解全球温室效应具有重大作用。根据耦联反应的不同,可将AOM分为3类,包括硫酸盐还原型、反硝化型以及铁锰依赖型。系统地介绍了AOM的类型及参与的微生物的特性,并对未来更多的AOM微生物的发现以及机理的研究提出展望,以期为甲烷排放控制和管理提供依据。更多还原

【Abstract】 Methane was a kind of greenhouse gas,its greenhouse effect was 20 times stronger than CO₂.Anaerobic oxidation of methane（AOM）by microbe was an important way to reduce methane emission in nature and had significant effect on alleviating the global warming.According to different coupling reactions,AOM could be divided into three types,including sulfate-dependent anaerobic methane oxidation（SAMO）,denitrification-dependent anaerobic methane oxidation（DAMO）and iron manganese-dependent AOM.The types of AOM and the characteristics of microbe involved were systematically summarized.In addition,the future research on the discovery of AOM microbe and the mechanism of AOM were put forward to provide the theoretical basis for the control and management of methane emission.更多还原
