Family : Halobacteriaceae
Genre : Halobacterium
Scientific name
Halobacterium
Elazari-Volcani 1957

Halobacterium is a genus of the order Halobacteriales to which numerous species belong. They are called (like all other halobacteria) extreme halophilic Euryarchaea because they need at least 20% salinity to grow. They mainly grow where high salt concentrations can be found, for example in salt lakes , salt pans or salted food.

The genera Halobacterium and Halococcus have the largest plasmids among the extremely halophilic archaea. The plasmid pR1SE from Halobacterium lacusprofundi R1S1 , found in the Antarctic, is even able to form vesicles (protective bubbles), which may represent a transitional or intermediate form to real viruses .
