Abstract

Desulfonatronum thiodismutans strain MLF1, an alkaliphilic bacterium capable of sulfate reduction, was isolated from Mono Lake, California. Here we report the 3.92-Mb draft genome sequence comprising 34 contigs and some results of its automated annotation. These data will improve our knowledge of mechanisms by which bacteria withstand extreme environments.

Highlights

  • Desulfonatronum thiodismutans strain MLF1, an alkaliphilic bacterium capable of sulfate reduction, was isolated from Mono Lake, California

  • Prokaryotes whose growth and survival depends on high pH are termed alkaliphiles [2]

  • Alkaliphilic bacteria face the major problem of maintaining an internal pH at a level not higher than approximately pH 8.5 and use a number of strategies to mitigate this problem [2]

Summary

Introduction

Desulfonatronum thiodismutans strain MLF1, an alkaliphilic bacterium capable of sulfate reduction, was isolated from Mono Lake, California. Alkaline aquatic environments (pH Ͼ9.0) are relatively uncommon on Earth and include soda lakes (some of which are hypersaline) and some hydrothermal springs. Despite the hostile conditions in soda lakes, they are among the most productive aquatic environments on the planet [1, 2]. Prokaryotes whose growth and survival depends on high pH are termed alkaliphiles [2].
