Methane was a kind of greenhouse gas,its greenhouse effect was 20times stronger than CO_2. 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.
