Euryarchaeota / Halobacteria / Haloferacales / Halorubraceae / Halorubrum With 37 species, Halorubrum (family Halorubraceae , order Haloferacales ) is the largest genus within the class Halobacteria . Cells of Halorubrum species are rod shaped or pleomorphic under optimal growth conditions and stain Gram‐negative. Some species are motile. Colonies are generally red‐orange due to the presence of bacterioruberin carotenoids, but some species are almost colorless; retinal pigments can also be present. Some strains produce gas vesicles. Halorubrum species are extremely halophilic, with growth occurring in media containing 1.0–5.2 M NaCl; the optimum magnesium concentration varies between 0.005 and 0.6 M. Cells lyse in distilled water. The genus contains both neutrophilic and alkaliphilic species. All are aerobic chemoorganotrophs; anaerobic growth of some species was reported in the presence of nitrate or arginine. Some species grow on single carbon sources. Most species use sugars, some with the production of acids. The major polar lipids are C 20 C 20 and sometimes C 20 C 25 glycerol diether derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulfate (in most species), and a sulfated glucosyl mannosyl diether, for some species identified as S‐DGD‐3. Alkaliphilic species lack glycolipids. The DNA G + C content is between 60.2 and 71.2 mol%. Halorubrum species have been isolated from marine salterns, salt lakes, soda lakes, saline soils, rock salt, salted foods, and other hypersaline environments. The type species is Halorubrum saccharovorum . Later homotypic synonym: Halorubrobacterium Kamekura and Dyall‐Smith 1996, 625 VP (Effective publication: Kamekura and Dyall‐Smith 1995, 345). DNA G + C content (mol%) : 60.2–71.2. Type species : Halorubrum saccharovorum (Tomlinson and Hochstein 1976) McGenity and Grant 1996, 362 VP (Effective publication: McGenity and Grant 1995, 241) ( Halobacterium saccharovorum Tomlinson and Hochstein 1977, 306; Halorubrobacterium saccharovorum (Tomlinson and Hochstein 1976) Kamekura and Dyall‐Smith 1996, 625).

Ha.lo'bi.um. Gr. masc. n. hals, halos salt; Gr. masc. n. bios life; N.L. neut. n. Halobium halophilic life. Euryarchaeota / Halobacteria / Haloferacales / Halorubraceae / Halobium The genus Halobium , classified within the family Halorubraceae, order Haloferacales in the class Halobacteria , consists of orange‐red pigmented, extremely halophilic pleomorphic cells. They are obligately aerobic chemoorganoheterotrophs, and anaerobic growth with nitrate, dimethyl sulfoxide, or l ‐arginine has not been observed. Oxidase and catalase reactions are positive. Major polar lipids include phosphatidylglycerol (PG), phosphatidylglycerol phosphate methyl ester (Me‐PGP), and sulfated diglycosyl diether (S‐DGD‐1). Currently, the genus consists of two species: Halobium palmae and Halobium salinum . Isolates have been recovered from solar salterns. DNA G + C content (mol%) : 67.0–68.9. Type species : Halobium palmae Mori, Nurcahyanto, Kawasaki, Lisdiyanti, Yopi and Suzuki 2016, 3803 VP .
