General Information: Chemoheterotrophic obligate extreme halophilic archeon. Halobacterial species are obligately halophilic microorganisms that have adapted to optimal growth under conditions of extremely high salinity 10 times that of sea water. This bacterium (strain R1; DSM 671) is an obligately halophilic archeon and represents the type species for the genus Halobacterium. The first recorded isolation of this organism came from the spoilage of salted fish. It is also commonly found in neutral salt lakes, marine salterns, proteinaceous products heavily salted with crude solar salt and ancient evaporate deposits.
