Methanofervidicoccus sp. A16 is a novel thermophilic and obligate hydrogenotrophic methanogen isolated from a deep-sea hydrothermal vent chimney sample at the Mid Cayman spreading center, Caribbean Sea. Here we report the complete genome of strain A16, which has one circular chromosome of 1,485,358 bp with a mean G+C content of 35.01 mol%. The complete genome harbors 1442 predicted protein-encoding genes. Genes involved in hydrogenotrophic methane production and N₂ fixation were identified in this genome. This study expands our knowledge of methanogenesis at high temperatures and the involvement of these microorganisms in the carbon and nitrogen cycles of deep-sea hydrothermal environments.

Methanofervidicoccus SP。A16是一种新型的嗜热专性氢营养型产甲烷菌，从加勒比海中部开曼群岛传播中心的深海热液排放烟囱样品中分离出来。在这里，我们报告了菌株A16的完整基因组，该菌株具有一个1,485,358 bp的圆形染色体，平均G + C含量为35.01 mol％。完整的基因组包含1442个预测的蛋白质编码基因。在该基因组中鉴定了涉及氢营养型甲烷产生和N ₂固定的基因。这项研究扩展了我们在高温下甲烷生成的知识，以及这些微生物在深海热液环境的碳和氮循环中的参与。
