: '' Note: The word "halobacterium" is also the singular form of the word "halobacteria".'' The Genus ''Halobacterium'' consists of several species of Archaea with an obligate Aerobic Metabolism which require an environment with a high concentration of Salt ; many of their Proteins will not function in low-salt environments. They grow on Amino Acids in their Aerobic conditions. Their Cell Walls are also quite different from those of Bacteria , as ordinary Lipoprotein Membranes fail in high salt concentrations. In shape, they may be either rods or Cocci , and in color, either red or purple (some species produce Bacteriorhodopsin ). They reproduce using Binary Fission (by constriction), and are Motile . Halobacterium grows best in a 37 degree Celsius environment. Halobacterium has 2,571,010 bp (base pairs) of DNA compiled into three circular strands. More specificaly, one large chromosome with 2,014,239 bp, and two smaller ones with 191,346 and 365,425 bp. It can be found in the Great Salt Lake, the Dead Sea, Lake Magadi, and any other waters with high salt concentration. Halobacterium contains a light sensitive pigment called bacteriorhodopsin that gives it its color, and provides chemical energy and pumps protons to the outside of the cell membrane. The protons that flow back are used in the synthesis of ATP, which is that energy source for a cell. Genus ''Halobacterium'':
