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

Regulated polyploidy in halophilic archaea.
PLoS 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.

A non-carboxylating pentose bisphosphate pathway in halophilic archaea [PDF]
Communications Biology, 2022 A nucleoside degradation pathway in halophilic archaea is identified, which converts the ribose moiety of guanosine to dihydroxyacetone phosphate and ethylene glycol.

Identification of acetylated diether lipids in halophilic Archaea [PDF]
MicrobiologyOpen, 2022 As a hallmark of Archaea, their cell membranes are comprised of ether lipids. However, Archaea‐type ether lipids have recently been identified in Bacteria as well, with a somewhat different composition: In Bacillales, sn‐glycerol 1‐phosphate is ...

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

Cellular differentiation into hyphae and spores in halophilic archaea [PDF]
Nature Communications, 2023 Several groups of bacteria have complex life cycles involving cellular differentiation and multicellular structures. For example, actinobacteria of the genus Streptomyces form multicellular vegetative hyphae, aerial hyphae, and spores.

DNA Repair and Photoprotection: Mechanisms of Overcoming Environmental Ultraviolet Radiation Exposure in Halophilic Archaea [PDF]
Frontiers 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

Positioning of the Motility Machinery in Halophilic Archaea [PDF]
mBio, 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.

Bipyrimidine Signatures as a Photoprotective Genome Strategy in G + C-rich Halophilic Archaea
Life, 2016 Halophilic archaea experience high levels of ultraviolet (UV) light in their environments and demonstrate resistance to UV irradiation. DNA repair systems and carotenoids provide UV protection but do not account for the high resistance observed.

Halophilic Archaea Halorhabdus Rudnickae and Natrinema Salaciae Activate Human Dendritic Cells and Orient T Helper Cell Responses [PDF]
Frontiers in Immunology, 2022 Halophilic archaea are procaryotic organisms distinct from bacteria, known to thrive in hypersaline environments, including salt lakes, salterns, brines and salty food. They have also been identified in the human microbiome.
