Key Points

To report the draft genome sequence of strain SR50, a newly cultivated member of the Archaeoglobaceae family.
Genome sequencing performed on strain SR50 isolated from a hydrothermal vent.
Characterization of growth capabilities as lithoautotrophic via sulfate reduction.
SR50 represents the first cultivated member of the genus JdFR-22 in the Archaeoglobaceae family.
Strain SR50 can grow lithoautotrophically by utilizing sulfate, demonstrating unique metabolic capabilities.

Implication

Draft genome sequencing reveals sulfate-reducing capabilities of SR50 from a hydrothermal vent, highlighting its ecological role.

Abstract

We report the draft genome sequence of SR50, the first cultivated member of the genus JdFR-22 within the Archaeoglobaceae family, which currently includes three genera with cultivated representatives. Isolated from a shallow hydrothermal vent off Saint-Paul Island, a strictly protected area, SR50 is able to grow lithoautotrophically by sulfate reduction.
