| 摘 要： | 综述了缺氧嗜甲烷古菌的分布、生态位、形态与代谢特征的新发现,并讨论了其与产甲烷菌的关系.在无氧条件下,缺氧嗜甲烷古菌与硫酸盐还原菌互养,氧化甲烷气体以阻止其进入大气.缺氧嗜甲烷古菌主要分布于深海甲烷渗漏区和冷泉区域,在其他多种缺氧环境中也能发现,由于还未获得纯培养,对这类微生物的生态位知之甚少.其细胞呈球状、杆状,有时聚集成球状集合体或连接形成丝状体.缺氧甲烷氧化可能经过"反甲烷合成"、"甲基合成"等路径.嗜甲烷古菌与产甲烷菌有着较近的亲缘关系,并且存在许多相似点.图1表1参37

| Abstract: | The distribution,niche,form and metabolism charateristics of anaerobic methanotrophs(ANME) are summarized,and the phylogenetic relationship between ANME and methanogenic archaea are discussed.Methane can be oxidized by syntrophism of ANME and sulfate-reducing bacteria under the oxygen deficit condition.ANME mainly distribute in deep-sea and cold-seep area,and generally associate sulfate-reducing bacteria to carry out anaerobic oxidation of methane by proposed reverse methanogenesis or methylogenesis pathway... |
