Archaeoglobaceae are a
family
Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Idea ...
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
''Archaeoglobus'' is a genus of the phylum Euryarchaeota. ''Archaeoglobus'' can be found in high-temperature oil fields where they may contribute to oil field souring.
Metabolism
''Archaeoglobus'' grow anaerobically at extremely high temperat ...

chemoorganotrophic sulfate-reducing archaea, the only known member of the
Archaea that possesses this type of metabolism. ''
Ferroglobus'', in contrast, are
chemolithotroph
Lithotrophs are a diverse group of organisms using an inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e.g., carbon dioxide fixation) or energy conservation (i.e., ATP production) via aerobi ...
