Halorubraceae
''Halorubraceae'' is a family of halophilic, chemoorganotrophic or heterotrophic archaea within the order ''Haloferacales.'' The type genus of this family is ''Halorubrum''. Its biochemical characteristics are the same as the order ''Haloferacales.'' The name ''Halorubraceae'' is derived from the Latin term ''Halorubrum,'' referring to the type genus of the family and the suffix "-ceae," an ending used to denote a family. Together, ''Halorubraceae'' refers to a family whose nomenclatural type is the genus ''Halorubrum.'' Current taxonomy and molecular signatures As of 2021, ''Halorubraceae'' contains nine validly published genera. This family can be distinguished from other Halobacteria by the presence of four conserved signature proteins (CSPs). 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).

Halobacteria
Haloarchaea (halophilic archaea, halophilic archaebacteria, halobacteria) are a class of the Euryarchaeota, found in water saturated or nearly saturated with salt. Halobacteria are now recognized as archaea rather than bacteria and are one of the largest groups. The name 'halobacteria' was assigned to this group of organisms before the existence of the domain Archaea was realized, and while valid according to taxonomic rules, should be updated. Halophilic archaea are generally referred to as haloarchaea to distinguish them from halophilic bacteria. These microorganisms are among the halophile organisms, that they require high salt concentrations to grow, with most species requiring more than 2.0M NaCl for growth and survival. They are a distinct evolutionary branch of the Archaea distinguished by the possession of ether-linked lipids and the absence of murein in their cell walls. Haloarchaea can grow aerobically or anaerobically. Parts of the membranes of haloarchaea are purpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halorubrum
''Halorubrum'' is a genus in the family Halorubraceae. ''Halorubrum'' species areusually halophilic and can be found in waters with high salt concentration such as the Dead Sea or Lake Zabuye. Genetic exchange A population of the haloarchaea ''Halorubrum'' in its natural high salt concentration environment exchanged genetic information frequently by recombination. This population exhibited a degree of linkage equilibrium approaching that of a sexual population. Taxonomy In taxonomy, ''Halorubrum'' is a genus of the Halobacteriaceae. Species ''Halorubrum ejinorense'' was first isolated from Lake Ejinor in Inner Mongolia, China. ''Halorubrum lacusprofundi'' was first isolated in the 1980s from Deep Lake, Antarctica. Its genome, sequenced in 2008, consists of two chromosomes (one 2.74 Mb and the other 0.53 Mb) and one plasmid (0.43 Mb). Its β-galactosidase enzyme has been extensively studied to understand how proteins function in low-temperature, high-saline environments. One ...

Haloferacales
''Haloferacales'' is an order of halophilic, chemoorganotrophic or heterotrophic archaea within the class Haloarchaea. The type genus of this order is ''Haloferax.'' The name ''Haloferacales'' is derived from the Latin term ''Haloferax,'' referring to the type genus of the order and the suffix "-ales," an ending used to denote an order. Together, ''Haloferacales'' refers to an order whose nomenclatural type is the genus ''Haloferax.'' Biochemical Characteristics and Molecular Signatures Members are halophiles and can be chemoorganotrophs or heterotrophs and are isolated from high-salt environments such as marine solar salterns and the Dead Sea. Some members are motile and contain gas vesicles. Morphology is variable, including rod, coccus or flat square shapes. Members of this order grow optimally in neutral pH. The DNA G+C content for this order ranges between 55-66 mol%. This order can be reliably distinguished from other Halobacteria by the presence of five conserved signatu ...

Haloquadratum
''Haloquadratum'' (common abbreviation: ''Hqr.'') is a genus of archaean, belonging to the family Haloferacaceae. The first species to be identified in this group, ''Haloquadratum walsbyi'', is unusual in that its cells are shaped like square, flat boxes. This halophilic archaean, discovered in 1980 by A.E. Walsby in the Gavish Sabkha, a coastal hypersaline pool (sabkha) on the Sinai Peninsula in Egypt, was not cultured until 2004. The cells typically contain polyhydroxyalkanoate (PHA) granules, as well as large numbers of refractile, gas-filled vacuoles which provide buoyancy in a watery environment and may help to position the cells to maximize light-harvesting. The cells may join with others to form fragile sheets up to 40 micrometres wide. ''H. walsbyi'' can be found anywhere in hypersaline waters. When sea water evaporates, high concentration and precipitation of calcium carbonate and calcium sulfate result, leading to a hypersaline sodium chloride-rich brine. ...
