Detailed explanation-1: -Halophiles are microorganisms that require certain concentrations of salt to survive, and they are found in both Eubacterial and Archaeal domains of life. In Eubacteria, halophiles are a very heterogeneous group, having members in at least eight different phyla.

Detailed explanation-2: -Halophiles are organisms represented by archaea, bacteria, and eukarya for which the main characteristic is their salinity requirement, halophilic “salt-loving”. Halophilic microorganisms constitute the natural microbial communities of hypersaline ecosystems, which are widely distributed around the world [1].

Detailed explanation-3: -Halophiles are found in all three domains of life. Within the Bacteria we know halophiles within the phyla Cyanobacteria, Proteobacteria, Firmicutes, Actinobacteria, Spirochaetes, and Bacteroidetes. Within the Archaea the most salt-requiring microorganisms are found in the class Halobacteria.

Detailed explanation-4: -Extreme halophiles grow best in concentrations of salt from 20% to 30%. Examples of extreme halophiles are Salinibacter ruber and organisms in the Halobacteria class. Extreme halophiles live in the Dead Sea in the Middle East and in man-made solar salterns (lakes used for making sea salt).
