Thermosulfurimonas marina strain SU872 is a thermophilic, anaerobic, chemolithoautotrophic bacterium, isolated from a shallow-sea hydrothermal vent in the Pacific Ocean near Kunashir Island, that is able to grow by disproportionation of inorganic sulfur compounds and dissimilatory nitrate reduction to ammonium. Here we report the complete genome sequence of strain SU872, which presents one circular chromosome of 1,763,258 bp with a mean G + C content of 58.9 mol%. The complete genome harbors 1827 predicted protein-encoding genes, 47 tRNA genes and 3 rRNA genes. Genes involved in sulfur and nitrogen metabolism were identified. This study expands our knowledge of sulfur and nitrogen use in energy metabolism of high temperatures areas of shallow-sea hydrothermal environments. In order to highlight Thermosulfurimonas marina metabolic features, its genome was compared with that of Thermosulfurimonas dismutans, the only other species described within the Thermosulfurimonas genus.
海洋栖热硫菌 SU872 菌株是一株嗜热、厌氧、化能自养细菌，从太平洋千岛群岛附近的浅海热液喷口分离得到，能够通过无机硫化合物的歧化作用和异化硝酸盐还原为铵来生长。在这里，我们报告了 SU872 菌株的完整基因组序列，该基因组呈现一条 1763258bp 的圆形染色体，平均 G+C 含量为 58.9mol%。完整基因组包含 1827 个预测的蛋白质编码基因、47 个 tRNA 基因和 3 个 rRNA 基因。鉴定出了参与硫和氮代谢的基因。这项研究扩展了我们对浅海热液环境高温区硫和氮在能量代谢中利用的认识。为了突出海洋栖热硫菌的代谢特征，将其基因组与该属中唯一描述的脱硫硫单胞菌进行了比较。
