Archaeoglobales

	Archaeoglobales 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 Natio ...

	Geoglobus Ahangari ''Geoglobus'' is a hyperthermophilic member of the Archaeoglobaceae within the Euryarchaeota. It consists of two species, the first, ''G. ahangari'', isolated from the Guaymas Basin hydrothermal system located deep within the Gulf of California. As a hyperthermophile, it grows best at a temperature of 88 °C and cannot grow at temperatures below 65 °C or above 90 °C. It possess an S-layer cell wall and a single flagellum. ''G. ahangari'' is an anaerobe, using poorly soluble ferric iron (Fe3+) as a terminal electron acceptor. It can grow either autotrophically using hydrogen gas (H2) or heterotrophically using a large number of organic compounds, including several types of fatty acids, as energy sources. ''G. ahangari'' was the first archaeon isolated capable of using hydrogen gas coupled to iron reduction as an energy source and the first anaerobe isolated capable of using long-chain fatty acids as an energy source. A second species was described ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	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 temperatures between 60 and 95 °C, with optimal growth at 83 °C (ssp. ''A. fulgidus'' VC-16). They are sulfate-reducing archaea, coupling the reduction of sulfate to sulfide with the oxidation of many different organic carbon sources, including complex polymers. ''A. lithotrophicus'' live chemolitho-autotrophically from hydrogen, sulfate and carbon dioxide. Also ''A. profundus'' grow lithotrophically, but while this species needs acetate and CO2 for biosynthesis they are heterotroph. The complete ''A. fulgidus'' genome sequence revealed the presence of a nearly complete set of genes for methanogenesis. The function of these genes in ''A. fulgidus'' remains unknown, while the lack of the enzyme methyl-CoM reductase does not allow fo ...

	Ferroglobus ''Ferroglobus'' is a genus of the Archaeoglobaceae.See the NCBIbr>webpage on Ferroglobus Data extracted from the ''Ferroglobus'' is a hyperthermophilic genus phylogenetically located within the Euryarchaeota. It consists of one species, ''F. placidus'', isolated from hydrothermal vent sediment off the coast of Italy. ''F. placidus'' grows best at 85 °C and a neutral pH. It cannot grow at temperatures below 65 °C or above 95 °C. Cells possess an S-layer cell wall and archaella. Metabolically, ''Ferroglobus'' is quite unique compared to its relative ''Archaeoglobus''. ''F. placidus'' was the first hyperthermophile discovered to grow anaerobically by oxidizing aromatic compounds such as benzoate coupled to the reduction of ferric iron (Fe3+) to ferrous iron (Fe2+). Hydrogen gas (H2) and sulfide (H2S) can also be used as energy sources. Due to its anaerobic lifestyle, nitrate (NO3−) is used as a terminal electron acceptor whereby it is converted to nitrit ...
