Abstract
Anoxybacter fermentans DY22613T 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 DY22613T in this genus. The genome contains 3,557,532bp with a G+C content of 35.88%. Genome sequence analysis of strain DY22613T 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 DY22613T, and contribute to better understand the role of this group in the biogeochemistry cycling of iron in deep-sea hydrothermal fields.
