On the Response of Halophilic Archaea to Space Conditions [PDF]

open access: yesLife, 2014
Microorganisms are ubiquitous and can be found in almost every habitat and ecological niche on Earth. They thrive and survive in a broad spectrum of environments and adapt to rapidly changing external conditions.

Positioning of the Motility Machinery in Halophilic Archaea [PDF]

open access: yesmBio, 2019
Bacteria and archaea exhibit tactical behavior and can move up and down chemical gradients. This tactical behavior relies on a motility structure, which is guided by a chemosensory system.

Regulated polyploidy in halophilic archaea.

open access: yesPLoS ONE, 2006
Polyploidy is common in higher eukaryotes, especially in plants, but it is generally assumed that most prokaryotes contain a single copy of a circular chromosome and are therefore monoploid.

DNA Repair and Photoprotection: Mechanisms of Overcoming Environmental Ultraviolet Radiation Exposure in Halophilic Archaea

open access: yesFrontiers in Microbiology, 2017
Halophilic archaea push the limits of life at several extremes. In particular, they are noted for their biochemical strategies in dealing with osmotic stress, low water activity and cycles of desiccation in their hypersaline environments. Another feature

Extreme halophilic Archaea: Halobacterium salinarum carotenoids characterization and antioxidant properties [PDF]

open access: yesHeliyon
Important marine microorganisms are resources of renewable energy that may face global population growth and needs. The application of biomass metabolites, such as carotenoids and their derivatives, may solve some agro-food health problems. Herein, a new

Carotenoids from Halophilic Archaea: A Novel Approach to Improve Egg Quality and Cecal Microbiota in Laying Hens [PDF]

open access: yesAnimals
Carotenoids from different sources have different structures and functions, and their dietary components benefit the health of various organisms. The effects of halophilic Archaea-derived C50 carotenoids on poultry egg quality and gut microbiota remain ...

Rock surfaces as reservoirs for airborne halophilic microorganisms in the Bochnia Salt Mine [PDF]

open access: yesFrontiers in Microbiology
Airborne halophilic archaea have recently been detected in subterranean salt mines, yet their origin in such dynamic environments remains unclear.

Halophilic archaea as tools for bioremediation technologies. [PDF]

open access: yesAppl Microbiol Biotechnol
Abstract Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to be alive, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundantly and widely distributed worldwide than initially expected.

Metabolism of halophilic archaea [PDF]

open access: yesExtremophiles, 2008
In spite of their common hypersaline environment, halophilic archaea are surprisingly different in their nutritional demands and metabolic pathways. The metabolic diversity of halophilic archaea was investigated at the genomic level through systematic metabolic reconstruction and comparative analysis of four completely sequenced species: Halobacterium ...

The immune system of halophilic archaea [PDF]

open access: yesMobile Genetic Elements, 2012
Prokaryotes have developed several strategies to defend themselves against foreign genetic elements. One of those defense mechanisms is the recently identified CRISPR/Cas system, which is used by approximately half of all bacterial and almost all archaeal organisms. The CRISPR/Cas system differs from the other defense strategies because it is adaptive,
