Protective Roles of Bacterioruberin and Intracellular KCl in the Resistance of Halobacterium salinarium against DNA-damaging Agents. [PDF]
Journal of Radiation Research, 1998 Halobacterium salinarium, a member of the extremely halophilic archaebacteria, contains a C50-carotenoid namely bacterioruberin. We have previously reported the high resistance of this organism against the lethal actions of DNA-damaging agents including ionizing radiation and ultraviolet light (UV).

Probing the Cl--pumping photocycle of pharaonis halorhodopsin : Examinations with bacterioruberin, an intrinsic dye, and membrane potential-induced modulation of the photocycle [PDF]
, 2015 Halorhodopsin (HR) functions as a light-driven inward Cl- pump. The Cl- transfer process of HR from Natronomonas pharaonis (NpHR) was examined utilizing a mutant strain, KM-1, which expresses large amount of NpHR in a complex with the carotenoid ...

Microbiology, 1989 SUMMARY: Halobacterium cutirubrum was cultured in a complex medium designed for extreme halophiles containing 4 M-NaCl in the absence or presence of bacitracin (7, 14 or 28 μM) with shaking at 37°C for 24 h. Bacitracin at 7 or 14 μM inhibited growth (50% and 100%, respectively), phospholipid synthesis (88% and 96%, respectively) and bacterioruberin ...

Effect of hydrogen index and sodium chloride concentration on bacterioruberin biosynthesis
Processes and Food Production EquipmentThis study investigated the effect of sodium chloride (NaCl) concentration and medium pH on the ability of Arthrobacter agilis wb28 to synthesize bacterioruberin. This compound is a carotenoid in nature and plays a functional role in protecting the cell against environmental stress, including oxidative and osmotic stress; therefore, it has attracted ...

Microbial diversity and microbial abundance in salt-saturated brines: Why are the waters of hypersaline lakes red? [PDF]
, 2009 Salt-saturated lakes such as the North Arm of Great Salt Lake and saltern crystallizer ponds contain 10-10 and more red microorganisms ml-1. Even the Dead Sea occasionally turns red due to microbial blooms.
