Halophiles have distribution all over the world and are especially present in the saline conditions. They are commonly found in saline lakes, desert conditions, saline soils and sea water. Evolution has played a significant role in making them halotolerant. Extraordinary quality of halophiles does not limit to the resistance to the saline environment but they also have diverse contribution to the humans. They have been reported to produce biofuels, bioplastics and many industrial enzymes stable at extreme conditions. Researches on halophiles open a broad area of opportunities to the scientific community and to the industry.
