Complex Effects of Cytochrome P450 Monooxygenase on Purple Membrane and Bacterioruberin Production in an Extremely Halophilic Archaeon: Genetic, Phenotypic, and Transcriptomic Analyses [PDF]
Frontiers in Microbiology, 2018 Halophilic archaea are known to produce a diverse array of pigments for phototrophy and photoprotection. The aim of this paper was to determine the role of a Halobacterium gene encoding the predicted cytochrome P450 monooxygenase (CYP174A1) in pigment ...

The C50 carotenoid bacterioruberin regulates membrane fluidity in pink-pigmented Arthrobacter species [PDF]
Archives of Microbiology, 2021 AbstractCarotenoids have several crucial biological functions and are part of the cold adaptation mechanism of some bacteria. Some pink-pigmented Arthrobacter species produce the rare C50 carotenoid bacterioruberin, whose function in these bacteria is unclear and is found mainly in halophilic archaea.

The Journal of Physical Chemistry B, 2017 Ultrafast photochemistry of pharaonis halorhodopsin (p-HR) in the intact membrane of Natronomonas pharaonis has been studied by photoselective femtosecond pump-hyperspectral probe spectroscopy with high time resolution. Two variants of this sample were studied, one with wild-type retinal prosthetic groups and another after shifting the retinal ...

Life in the brine of Lunenburg, Germany: unveiling microorganisms associated with Zechstein salt deposits [PDF]
Frontiers in MicrobiologyIntroductionThe presence of hypersaline brines on other planets and moons in the inner and outer Solar System has been well established. Hence, any theory of life on other planets must consider microorganisms adapted to high salt concentrations.
