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 ...

Archaeoglobi
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.

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 ...

List Of Archaea Genera
This article lists the genera of the Archaea. The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI). Phylogeny National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using phylorank and the taxonomy manually curated to remove polyphyletic groups. Cladogram was taken from the GTDB release 07-RS207 (8th April 2022). The position of clades with a "question mark" are based on the additional phylogeny of the 16S rRNA-based LTP_12_2021 by The All-Species Living Tree Project. Phylum " Altarcha ...

Archaea
Archaea ( ; singular archaeon ) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat, square cells of ''Haloquadratum walsbyi''. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved ...

Nitrate
Nitrate is a polyatomic ion A polyatomic ion, also known as a molecular ion, is a covalent bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. The term molecule may or may no ... with the chemical formula . salt (chemistry), Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are solubility, soluble in water. An example of an insoluble nitrate is bismuth oxynitrate. Structure The ion is the conjugate acid, conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. This charge results from a combination formal charge in which each of the three oxygens carries a − charge, whereas the nitrogen carries a +1 charge, all these adding up to formal c ...

Pearson Prentice Hall
Prentice Hall was an American major educational publisher owned by Savvas Learning Company. Prentice Hall publishes print and digital content for the 6–12 and higher-education market, and distributes its technical titles through the Safari Books Online e-reference service. History On October 13, 1913, law professor Charles Gerstenberg and his student Richard Ettinger founded Prentice Hall. Gerstenberg and Ettinger took their mothers' maiden names, Prentice and Hall, to name their new company. Prentice Hall became known as a publisher of trade books by authors such as Norman Vincent Peale; elementary, secondary, and college textbooks; loose-leaf information services; and professional books. Prentice Hall acquired the training provider Deltak in 1979. Prentice Hall was acquired by Gulf+Western in 1984, and became part of that company's publishing division Simon & Schuster. S&S sold several Prentice Hall subsidiaries: Deltak and Resource Systems were sold to National Education ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
