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 ...

Retention of the 4- pro - R hydrogen atom of mevalonate at C-2,2′ of bacterioruberin in Halobacterium halobium [PDF]
Biochemical Journal, 1980 Intact cells of Halobacterium halobium fed with (3R,4R)-[2-14C,4-3H1]mevalonic acid were found to incorporate label into acyclic C40 and C50 carotenoids, of which bacterioruberin was the most abundant. The 14C/3H ratios of the isolated carotenoids demonstrated that the 4-pro-R hydrogen atom of mevalonic acid was retained at the C-2 and C-2′ positions ...

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 ...
