“…Salt‐saturated brines in hypersaline lakes and other hypersaline environments such as saltern crystallizer ponds are characteristically inhabited by dense communities of red halophilic Archaea (family Halobacteriaceae ) (Oren, ). The unicellular green alga Dunaliella is an integral part of such ecosystems, but the role of the Bacteria at the highest salt concentrations was generally considered negligible.…”

The existence of large number of a member of the Bacteroidetes in NaCl-saturated brines in saltern crystallizer ponds was first documented in 1999 based on fluorescence in situ hybridization studies. Isolation of the organism and its description as Salinibacter ruber followed soon. It is a rod-shaped, red-orange pigmented, extreme halophile that grows optimally at 20-30% salt. The genus is distributed worldwide in hypersaline environments. Today, the genus Salinibacter includes three species, and a somewhat less halophilic relative, Salisaeta longa, has also been documented. Although belonging to the Bacteria, Salinibacter shares many features with the Archaea of the family Halobacteriaceae that live in the same habitat. Both groups use KCl for osmotic adjustment of their cytoplasm, both mainly possess salt-requiring enzymes with a large excess of acidic amino acids, and both contain different retinal pigments: light-driven proton pumps, chloride pumps, and light sensors. Salinibacter produces an unusual carotenoid, salinixanthin that forms a light antenna and transfers energy to the retinal group of xanthorhodopsin, a light-driven proton pump. Other unusual features of Salinibacter and Salisaeta include the presence of novel sulfonolipids (halocapnine derivatives). Salinibacter has become an excellent model for metagenomic, biogeographic, ecological, and evolutionary studies.

“…amylolyticus) [10]. Besides their optimal pH for growth (8-9.5), another common feature of haloalkaliphilic archaea is the modest requirement for divalent cations in accordance with the low Mg 2+ and Ca 2+ availability in their original habitat [10]. In line with this property is the presence of a tentative calcium-binding outer membrane-like protein (GeneBank ID 397775179; 176 aa) that seems to be unique in the alkaliphilic members of the recently proposed Natrialbales order [11].…”
