摘要
甲烷是重要的温室气体,也是新的清洁能源。甲烷是产甲烷菌代谢的最终产物。产甲烷菌基因组学的研究使人们对其基因信息、结构和代谢有了更深的认识。产甲烷菌的代谢底物类型有很多种,嗜冷产甲烷菌是甲基营养型,H2/CO2和(或)甲基类化合物是其主要的代谢底物类型。嗜温产甲烷菌代谢底物类型最多,H2/CO2、甲基类化合物和乙酸盐均有可能作为底物利用。H2/CO2和甲基类化合物是嗜热产甲烷菌的主要前体物质。
Methane is an important greenhouse gas and new clean energy. Methane is a final product of methanogens metabolism. The genome information told us a comprehensive view of the gene information, structure and metabolism. There are lots of types of metabolic substrates of methanogenic bacteria. Psychrophilic methanogens are identified as methyl nutrition, which was fed by H2/CO2and（or） methyl compounds. Mesophilic methanogenic bacteria possessed a maximun of metabolic substrate. Methanogens are likely to used H2/CO2, methyl compounds and acetates as sources for growth and methanogenesis. Simultaneously, H2/CO2and methyl compounds are the main methane for thermophilic methanogens.
