<P> Halobacterium salinarum is an extremely halophilic marine Gram - negative obligate aerobic archaeon . Despite its name , this is not a bacterium , but rather a member of the domain Archaea . It is found in salted fish , hides , hypersaline lakes , and salterns . As these salterns reach the minimum salinity limits for extreme halophiles , their waters become purple or reddish color due to the high densities of halophilic Archaea . H. salinarum has also been found in high - salt food such as salt pork , marine fish , and sausages . The ability of H. salinarum to survive at such high salt concentrations has led to its classification as an extremophile . </P>
