Anoxybacter fermentans DY22613 is a novel piezophilic dissimilatory iron(III)-reducing bacterium isolated from East Pacific Rise (EPR) hydrothermal sulfides. The strain shows very low 16S rRNA gene similarity (86.92%) with the Halanaerobiales, and represents at least a novel genus Anoxybacter within the class Clostridia. Here, we describe the first complete genome of strain DY22613 in this genus. The genome contains 3,557,532 bp with a G + C content of 35.88%. Genome sequence analysis of strain DY22613 reveals the presence of genes encoding riboflavin (ribBA,D,A,F,H), FAD‑hydrogenases, etc. are involved in dissimilatory iron(III)-reducing process. The genome will provide insights into the mechanism of dissimilatory iron(III)-reducing in strain DY22613, and contribute to better understand the role of this group in the biogeochemistry cycling of iron in deep-sea hydrothermal fields.
耐冷好氧反硝化菌 DY22613 是一种新型的太平洋东脊（EPR）热液硫化物中分离出的嗜压异化铁（III）还原菌。该菌株与盐厌氧菌的 16S rRNA 基因相似度非常低（86.92%），在梭菌纲中代表至少一个新型的耐冷好氧反硝化菌属。在这里，我们描述了该属中 DY22613 菌株的第一个完整基因组。基因组包含 3,557,532bp，G+C 含量为 35.88%。DY22613 菌株的基因组序列分析表明，存在编码核黄素（ribBA、D、A、F、H）、FAD-氢化酶等的基因，这些基因参与异化铁（III）还原过程。该基因组将为 DY22613 菌株异化铁（III）还原的机制提供深入了解，并有助于更好地理解该菌群在深海热液场中铁的生物地球化学循环中的作用。
