Anaerobic growth of halobacteria.
Proceedings of the National Academy of Sciences, 1980 An energy-transducing pathway in halobacteria is described. Arginine mediates substrate level phosphorylation and allows the cells to grow anaerobically. Bacteriorhodopsin plus light can function as an alternative energy source under these conditions, provided the cells contain the pigment when transferred to the anaerobic environment.

An identity card for sabkha dolomite
The Depositional Record, Volume 12, Issue 1, February 2026.An ‘identity card’ for modern sabkha dolomite from Qatar reveals its mineralogical, geochemical and microbial characteristics. This integrated dataset provides a benchmark for recognising similar dolomites in the rock record and for calibrating paleoenvironmental proxies used in climate and biosignature studies.

Lipid composition of integral purple membrane by 1H and 31P NMR
Journal of Lipid Research, 2005 In the purple membrane (PM) of halobacteria, lipids stabilize the trimeric arrangement of bacteriorhodopsin (BR) molecules and mediate the packing of the trimers in a regular crystalline arrangement.

Characterization and Functional Evaluation of Carotenoids From Haloarcula rubripromontorii BS2
MicrobiologyOpen, Volume 15, Issue 1, February 2026.Fractionation and comprehensive characterization of C50 carotenoids from Haloarcula rubripromontorii BS2, identified all‐trans bacterioruberin as the predominant isomer. The haloarchaeal carotenoid exhibited strong antioxidant activity, photostability in oil and was biocompatible with human keratinocytes, highlighting their potential as sustainable ...

Exploring tRNA gene cluster in archaea
Memorias do Instituto Oswaldo Cruz, 2019 BACKGROUND Shared traits between prokaryotes and eukaryotes are helpful in the understanding of the tree of life evolution. In bacteria and eukaryotes, it has been shown a particular organisation of tRNA genes as clusters, but this trait has not been ...

Martian Water: Are There Extant Halobacteria on Mars? [PDF]
Astrobiology, 2001 On Earth, life exists in all niches where water exists in liquid form for at least a portion of the year. On Mars, any liquid water would have to be a highly concentrated brine solution. It is likely, therefore, that any present-day Martian microorganisms would be similar to terrestrial halophiles. Even if present-day life does not exist on Mars, it is
