Anoxybacter fermentans DY22613^T 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^T in this genus. The genome contains 3,557,532 bp with a G + C content of 35.88%. Genome sequence analysis of strain DY22613^T 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^T, and contribute to better understand the role of this group in the biogeochemistry cycling of iron in deep-sea hydrothermal fields.

发酵发酵乳杆菌DY22613 ^T是一种从东太平洋上升（EPR）热液硫化物中分离出来的新型减少嗜压异化铁（III）的细菌。该菌株显示非常低的16S rRNA基因的相似性（86.92％）与Halanaerobiales，并代表至少一个新的属Anoxybacter类内梭菌。在这里，我们描述了该属DY22613 ^T菌株的第一个完整基因组。基因组包含3,557,532 bp，G + C含量为35.88％。菌株DY22613 ^T的基因组序列分析表明存在编码核黄素的基因（ribBA，D，A，F，H），FAD氢化酶等参与异化铁（III）的还原过程。该基因组将提供对DY22613 ^T菌株异化铁（III）还原机理的见解，并有助于更好地了解该组在深海热液场中铁的生物地球化学循环中的作用。
