Abstract: Seven efficient carotenoid producing Halophiles were isolated and characterized from Solar saltern of Mulund, Mumbai, Maharashtra. Of these, a Gram negative aerobic rod shaped organisms SS-12 was selected for carotenoid production. It was identified as Halorubrum sp. using cultural, microscopic and biochemical characterization. Isolate SS-12 showed luxuriant growth at 20% NaCl concentration, 35°C temperature and at 7 pH. Spectophotometric analysis of pigment revealed that the pigment is bacterioruberin type. The antioxidant activity exhibited by extracted pigments was equivalent to the antioxidant activity of lutein and astaxanthin at 4 mM concentration.
