Salinibacter ruber is an extremely halophilic red bacterium that was found in saltern crystallizer ponds in Alicante and Mallorca, Spain in 2002 by Anton et al.. This environment has very high salt concentrations, and Salinibacter ruber itself cannot grow at below 15% salt concentration, with an ideal concentration between 20-30%. Salinibacter ruber survives in this harsh environment because of its adaptations in order to cope with the high salt concentrations. These adaptations are: modifying the sequences of its proteins, recruiting proteins from different sources with different functions, as well as lateral gene transfer from other halophilic organisms.
This bacterium is very interesting because of its extremophile tendencies as a bacteria, where this is common mostly in the domain Archaea. Bacteria do not, in general, play a large role in microbial communities of hypersaline brines at or approaching NaCl saturation. However, with the discovery of S. ruber, this belief was weakened. It was found that S. ruber made up from 5% to 25% of the total prokaryotic community of the Spanish saltern ponds.Cite error: A <ref> tag is missing the closing </ref> (see the help page). It is red-pigmented, motile, rod-shaped, and extremely halophilic. The type strain is strain M31T(= DSM 13855T = CECT 5946T).
