Methanospirillum hungatei strain JF1 (DSM 864) is a methane-producing archaeon and is the type species of the genus Methanospirillum, which belongs to the family Methanospirillaceae within the order Methanomicrobiales. Its genome was selected for sequencing due to its ability to utilize hydrogen and carbon dioxide and/or formate as a sole source of energy. Ecologically, M. hungatei functions as the hydrogen- and/or formate-using partner with many species of syntrophic bacteria. Its morphology is distinct from other methanogens with the ability to form long chains of cells (up to 100 μm in length), which are enclosed within a sheath-like structure, and terminal cells with polar flagella. The genome of M. hungatei strain JF1 is the first completely sequenced genome of the family Methanospirillaceae, and it has a circular genome of 3,544,738 bp containing 3,239 protein coding and 68 RNA genes. The large genome of M. hungatei JF1 suggests the presence of unrecognized biochemical/physiological properties that likely extend to the other Methanospirillaceae and include the ability to form the unusual sheath-like structure and to successfully interact with syntrophic bacteria.
亨氏甲烷螺菌菌株JF1（DSM 864）是一种产甲烷古菌，是甲烷螺菌属的模式种，属于甲烷微菌目甲烷螺菌科。因其能够利用氢气和二氧化碳及/或甲酸作为唯一能源，其基因组被选择进行测序。在生态方面，亨氏甲烷螺菌与许多互营细菌物种一起作为利用氢气和/或甲酸的伙伴发挥作用。其形态与其他产甲烷菌不同，能够形成细胞长链（长度可达100μm），这些长链被包裹在鞘状结构内，且末端细胞带有极生鞭毛。亨氏甲烷螺菌菌株JF1的基因组是甲烷螺菌科第一个完全测序的基因组，它有一个3,544,738 bp的环状基因组，包含3,239个蛋白质编码基因和68个RNA基因。亨氏甲烷螺菌JF1的大基因组表明存在未被认识的生化/生理特性，这些特性可能延伸到其他甲烷螺菌科成员，包括形成不寻常鞘状结构以及与互营细菌成功相互作用的能力。
