General Information: Chromohalobacter salexigens DSM 3043 was first isolated from a solar salt facility on Bonaire Island, Netherlands Antilles. A moderate halophile which can grow on a variety of salts. 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. Several plasmids have been isolated from this organism. Plasmid pMH1 contains genes for resistance to kanamycin, neomycin, and tetracycline. A smaller plasmid, pHE1, which does not code for antibiotic resistance genes, has also been isolated.
