摘要：
The massive emission of CO2 during the combustion of fossil fuels has attracted researchers' attention about the biological methanation of CO2 . In the process of anaerobic organic matter biodegradation, the flora associated with the biological methanation of CO2 are mainly anaerobic hydrogenotrophic methanogens. Researchers have focused on the effect of temperature on the process of anaerobic hydrogenotrophic methanogenesis, which is important to promote the development of anaerobic hydrogenotrophic methanogenesis. In this paper, we introduced the important roles of hydrogenotrophic methanogens in anaerobic biodegradation processes, and summarized 32 obligate hydrogenotrophic methanogens that utilize only H2 and CO2 for CH4 production. We also showed that hydrogen can be derived from the decomposition of fossil fuels, biomass, water, and industrial gases. Then, the efficacy of anaerobic hydrogenotrophic methanogenesis at different temperature ranges were reviewed, and the effects of different temperature change ways on anaerobic hydrogenotrophic methanogenesis were presented. Finally, an outlook was put forward from the aspects of hydrogen sources and temperature change. © 2021, Chemical Industry Press Co., Ltd. All rights reserved.
