The Genus Archaeoglobus

Archeal Sulfate Reducers
The domain Archaea contains two genera, thermophilic Archaeoglobus and thermoacidophilic Caldivirga, which obtain energy by reducing oxidized sulfur compounds to H2S under anaerobic conditions. Both Archaeoglobus fulgidus and Caldivirga maquilingensis thrive at 85°C, the optimal temperature for growth (Itoh et al., 1999).
The genus Archaeoglobus is classified in the Archaeoglobaceae family, Archaeoglobales order, Archaeoglobi class, Euryarchaeota phylum, of the domain Archaea (Huber and Stetter, 2001). Archaeoglobus is a chemolithoautotrophic or chemoorganotrophic microorganism using sulfate, sulfite or thiosulfate as electron acceptor, with the formation of hydrogen sulfide as the end product.
Dissimilatory sulfate-reducers inhabit aquatic and terrestrial sediments and play an essential role in the biogeochemical sulfur cycle. Although oxygen is the most abundant terrestrial element on earth and more electro ...
