Complete genome sequence of hyperthermophilic archaeon Thermococcus sp. ES1

Thermococcus sp. strain ES1 is an anaerobic, hyperthermophilic archaeon from a hydrothermal vent that catabolizes sugars and peptides and produces H 2 S from S°, H 2 , acetate and CO 2 as its primary metabolites. We present the complete genome sequence of this strain (1,957,742 bp) with a focus on its substrate utilization and metabolite production capabilities. The sequence will contribute to the development of heterotrophic archaea for bioenergy production and biogeochemical modeling in hydrothermal environments.
