Archaeoglobaceae
Archaeoglobaceae are a family of the Archaeoglobales. All known genera within the Archaeoglobaceae are hyperthermophilic and can be found near undersea hydrothermal vents. Archaeoglobaceae are the only family in the order "Archaeoglobales", which is the only order in the class "Archaeoglobi". Mode of metabolism. While all genera within the Archaeoglobaceae are related to each other phylogenetically, the mode of metabolism used by each of these organisms is unique. "Archaeoglobus" are chemoorganotrophic sulfate-reducing archaea, the only known member of the Archaea that possesses this type of metabolism. "Ferroglobus", in contrast, are chemolithotrophic organisms that couple the oxidation of ferrous  iron to the reduction of nitrate. "Geoglobus" are iron reducing-archaea that use hydrogen gas or organic compounds as energy sources. Phylogeny. The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) and the phylogeny is based on 16S rRNA-based LTP release 106 by 'The All-Species Living Tree' Project. Notes: ♠ Strain found at the National Center for Biotechnology Information (NCBI) but not listed in the List of Prokaryotic names with Standing in Nomenclature (LPSN)
