Thermosphaera aggregans Huber et al. 1998 is the type species of the genus Thermosphaera, which comprises at the time of writing only one species. This species represents archaea with a hyperthermophilic, heterotrophic, strictly anaerobic and fermentative phenotype. The type strain M11TL(T) was isolated from a water-sediment sample of a hot terrestrial spring (Obsidian Pool, Yellowstone National Park, Wyoming). Here we describe the features of this organism, together with the complete genome sequence and annotation. The 1,316,595 bp long single replicon genome with its 1,410 protein-coding and 47 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
Keywords: Crenarchaeota; Desulfurococcaceae; GEBA; hot solfataric spring; hyperthermophile; obligate anaerobic; strictly fermentative metabolism; sulfur reduction.
