## TL;DR

This paper presents the draft genome of a new deep-sea bacterium that can grow by converting sulfur.

## Contribution

The study provides a new genome sequence for a sulfur-disproportionating bacterium from a deep-sea hydrothermal vent.

## Key findings

- The genome of Desulfobacterota strain M19 was sequenced.
- The bacterium is capable of autotrophic growth through sulfur disproportionation.

## Abstract

The draft genome sequence of Desulfobacterota strain M19, likely representing a new genus, is reported. It was isolated from a deep-sea hydrothermal vent and is capable of autotrophic growth by anaerobic disproportionation of elemental sulfur. Its genome has been sequenced because there are few publicly available genomes of sulfur-disproportionators.

## Full-text entities

- **Chemicals:** sulfur (MESH:D013455)
