Haloarcula
''Haloarcula'' (common abbreviation ''Har.'') is a genus of extreme halophilic Archaea in the class of Halobactaria. Cell Structure ''Haloarcula'' species can be distinguished from other genera in the family Halobacteriaceae by the presence of specific derivatives of TGD-2 polar lipids. ''H. quadrata'' has predominantly flat, square-shaped, somewhat pleomorphic cells. Metabolism ''H. quadrata'' was first isolated when researchers were attempting to culture ''Haloquadratum walsbyi'', a haloarchaeon that was thought to be unculturable until 2004. Similar to other halophilic archaea, ''Haloarcula'' species grow optimally at 40–45 °C. Growth appears in sheets of up to 65 cells often in the shape of a square or triangle. Taxonomy The genus of ''Haloarcula'' was long grouped with other halophilic archaea such as '' Halobacterium'' until genomic analysis prompted to reorder this genus in the new family of Haloarculaceae.

Haloarculaceae
''Haloarculaceae'' is a family of halophilic and mostly chemoorganotrophic archaea within the order ''Halobacteriales''. The type genus of this family is ''Haloarcula.'' Its biochemical characteristics are the same as the order ''Halobacteriales.'' The name ''Haloarculaceae'' is derived from the Latin term ''Haloarcula,'' referring to the type genus of the family and the suffix "-ceae," an ending used to denote a family. Together, ''Haloarculaceae'' refers to a family whose nomenclatural type is the genus ''Haloarcula.'' Current Taxonomy and Molecular Signatures As of 2021, ''Haloarculaceae'' contains 10 validly published genera. This family can be molecularly distinguished from other Halobacteria by the presence of 19 conserved signature proteins (CSPs) and seven conserved signature indels (CSIs) present in the following proteins: acetylglutamate kinase, ribonuclease R, metallo-beta-lactamase, tRNA modifying enzyme, carbamoyl phosphate synthase large subunit and hypothetical ...

Haloarcula Marismortui
''Haloarcula marismortui'' is a halophilic archaeon isolated from the Dead Sea Morphology ''Haloarcula marismortui'' is a Gram-negative archaeon with a cell size of 1.0-2.x 2.0-3.0 μm (diameter x length). Cells are pleomorphic appearing as short rods to rectangles. ''H. marismortui'' is motile via archaellum and possesses a cell membrane that consists of triglycosyl, diether lipids, and glycoproteins. Metabolism ''H. marismortui'' is an aerobic chemoorganotroph that utilizes glycolysis and a modified Entner-Doudaroff pathway for the breakdown of nutrients. ''H. marismortui'' utilizes energy sources such as glucose, sucrose, fructose, glycerol, malate, acetate & succinate while producing nitrogen, metabolic carbon, and acid as byproducts. Can also grow anaerobically by using nitrate as an electron acceptor. Genomic Properties The genome of ''H. marismortui'' is organized into nine circular replicons, in which individual G+C content varies from 54 to 62%. ''H. marismortui'' ...

Haloarcula Quadrata
''Haloarcula quadrata'' is a species of archaea discovered in a brine pool in the Sinai peninsula of Egypt. It was one of the first strains of prokaryotes whose cells show a flat, box-like shape. They were categorized as Haloarcula on the basis of their polar lipid composition. Morphology and metabolism The cells move using single or multiple flagella but lack gas vacuoles. Species within the genus ''Haloarcula'' are Gram negative and extremely halophilic, and they can use any of several sources of carbon Carbon () is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with o ....
