A denitrifying bacterium Halomonas sp. SS10-MC5, was isolated from a deep-sea hydrothermal vent chimney sample of the Indian Ocean. Here we described the complete genome of strain SS10-MC5 which has one circular chromosome of 4,441,120 bp with a mean G + C content of 66.12 mol%. The complete genome harbors 4094 predicted protein-encoding genes, 65 tRNA genes as well as four 16S-23S-5S rRNA operons. Genes involved in denitrification, assimilation, PHA synthesis, stress response, and so on, were identified in this genome. These metabolic features and related genes revealed genetic basis for the adaptation to the marine environment, which help to further understand its adaptive evolution and ecological role in submarine hydrothermal environments.
从印度洋深海热液喷口烟囱样本中分离到一株反硝化细菌 Halomonas sp. SS10-MC5。本研究描述了 SS10-MC5 菌株的完整基因组，该基因组为一个大小为 4,441,120 bp 的环状染色体，GC 含量为 66.12 mol%。完整基因组包含 4094 个预测蛋白编码基因、65 个 tRNA 基因和四个 16S-23S-5S rRNA 操纵子。在这个基因组中鉴定到参与反硝化、同化、PHA 合成、应激反应等的基因。这些代谢特征和相关基因揭示了其对海洋环境适应的遗传基础，有助于进一步了解其在海底热液环境中的适应进化和生态作用。
