Salinibacter ruber is an extremely halophilic red bacterium that was found in saltern crystallizer ponds in Alicante and Mallorca, Spain in 2002 by Antón 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.
