This bacteria is very interesting because of it extremophile tendencies as a bacteria, when 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! (2)

Salinibacter ruber is most closely related to the genus Rhodothermus which is a thermophilic, slightly halophilic bacteria. Though genetically it is considered to be closest to the Rhodothermus genus, it is most comparable to the family Halobacteriaceae, because of similarity in protein structure.

Salinibacter ruber

Description and significance

Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.

Salinibacter ruber is an extremely halophilic red bacteria and was found in saltern crystallizer ponds in Alicante and Mallorca, Spain. This environment has very high salt concentrations, and Salinibacter ruber itself cannot grow below 15% salt concentration, with an ideal concentration between 20-30%. Salinibacter ruber survives in this harsh environment because of an adaptation in order to cope with the high salt concentrations.

This bacteria is very interesting because of it extremophile tendencies as a bacteria, when 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! (2)

Salinibacter ruber is most closely related to the genus Rhodothermus which is a thermophilic, slightly halophilic bacteria. Though genetically it is considered to be closest to the Rhodothermus genus, it is most comparable to the family Halobacteriaceae, because of similarity in protein structure.

Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?

Cell structure and metabolism

Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.

Ecology

Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.

Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.

Application to Biotechnology

Does this organism produce any useful compounds or enzymes? What are they and how are they used?
