This bacterium is a moderate halophile, yet does not require high concentrations of sodium chloride. The salt requirements of this organism can be met by ions of other salts, such as potassium, rubidium, ammonium, bromide, and others.

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?

DNA Bases: 3696649

Chromosome Type: Circular

Total Genes: 3403

Protein Coding Genes: 3319
RNA Genes:              84
Pseudo Genes:           21

Cell structure and metabolism

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

The growth rate of Chromohalobacter salexigens DSM 3043 can be stimulated in media containing 0.3 M NaCl by a 0.7 M concentration of other salts of Na+, K+, Rb+, or NH4+, Cl-, Br-, NO3-, or SO4(2-) ions.

Ecology

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

Pathology

C. Salexigens is not known to be pathogenic

Application to Biotechnology

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