| 摘 要： | 甲烷是仅次于CO2的第二大温室气体,因此环境中甲烷来源的研究在环境保护方面具有重要意义.大气中甲烷的浓度(体积分数)约为1.7×10-6,其中约有75%来源于产甲烷菌的代谢.产甲烷菌是一类厌氧古生菌,其分类主要依据为16S rRNA以及其他生化指标.产甲烷菌主要以乙酸、H2和CO2及甲基类化合物为底物并以甲烷为终产物.产甲烷菌生命活动过程深受自然环境的影响.本文从产甲烷菌的发现、形态、分类、代谢机制、生态学研究方面介绍产甲烷菌的研究概况.

| Abstract: | Methane is the second most important greenhouse gas in the atmosphere with a concentration (rate by volume) of 1.7×10-6. Approximately 75% of methane in atmosphere comes from the activity of methanogens in the worldwide. The methanogens are anaerobic archaebacteria, according to 16S rRNA and other biochemical taxonomy. The methanogens can use compounds such as acetic acid, hydrogen and CO2 athylamine as substrates for methane production. The biochemical metabolisms of methanogens are greatly affected by natural environment where they live in. This paper will present a general situation of methanogens in term of history, morphology, taxonomy, metabolisms and ecology. |
