Abstract

Desulfuribacillus alkaliarsenatis AHT28T is an obligately anaerobic, sulfur- and arsenate-reducing haloalkaliphile that was isolated from Russian soda lake sediments. Here, we present the 3.1-Mb draft genome sequence for this strain, consisting of 36 contigs with a G+C content of 37.5% and 2,978 protein-coding sequences.

Highlights

Sulfidogenesis is the process by which sulfide is produced through microbial reduction of oxidized sulfur compounds such as sulfate, sulfite, thiosulfate, and elemental sulfur
Elemental sulfur reduction appears to be widespread in alkaline, hypersaline (Ͼ3.5% salt) soda lakes, with activities having been observed to surpass that of sulfate reduction under conditions of salt saturation [1]
Even though sulfur reduction is a potentially important biogeochemical process in soda lakes, relatively little is known about the phylogeny and physiology of sulfur-respiring haloalkaliphiles

Summary

Introduction

Sulfidogenesis is the process by which sulfide is produced through microbial reduction of oxidized sulfur compounds such as sulfate, sulfite, thiosulfate, and elemental sulfur. Elemental sulfur reduction appears to be widespread in alkaline (pH 9 to 11), hypersaline (Ͼ3.5% salt) soda lakes, with activities having been observed to surpass that of sulfate reduction under conditions of salt saturation [1]. Even though sulfur reduction is a potentially important biogeochemical process in soda lakes, relatively little is known about the phylogeny and physiology of sulfur-respiring haloalkaliphiles. Five bacterial and two archaeal strains have been isolated and described [2].
