Genomic variation and biogeography of Antarctic haloarchaea [PDF]

Microbiome, 2018
Background The genomes of halophilic archaea (haloarchaea) often comprise multiple replicons. Genomic variation in haloarchaea has been linked to viral infection pressure and, in the case of Antarctic communities, can be caused by intergenera gene ...

Decoding the Chemical Language of Ribosomally Synthesized and Post-Translationally Modified Peptides from the Untapped Archaea Domain. [PDF]

Angew Chem Int Ed Engl
Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

Analysis of Carotenoids in Haloarchaea Species from Atacama Saline Lakes by High Resolution UHPLC-Q-Orbitrap-Mass Spectrometry: Antioxidant Potential and Biological Effect on Cell Viability

Antioxidants, 2021
Haloarchaea are extreme halophilic microorganisms belonging to the domain Archaea, phylum Euryarchaeota, and are producers of interesting antioxidant carotenoid compounds.

A Spotlight on Archaea in Humans, Livestock and Poultry: A Review. [PDF]

Vet Med Sci
The microbiota includes prokaryotes (archaea and bacteria) and eukaryotes. Archaea are single‐celled prokaryotes and essential part of gut microbiome. Researches on archaea in ruminants and humans are more than mono‐gastric. The low abundance of archaea in the gut depends on the method used (metagenomics or meta‐transcriptomic) and age of people or ...

Rhomboid proteases: key players at the cell surface within haloarchaea [PDF]

Frontiers in Microbiology
IntroductionRhomboid proteases are intramembrane serine proteases that play a key role in regulating membrane proteins across all domains of life. However, their function in archaea remains poorly understood.

Haloarchaea as emerging big players in future polyhydroxyalkanoate bioproduction: Review of trends and perspectives

Current Research in Biotechnology, 2022
Haloarchaea comprise the extremely halophilic branch of the phylum Euryarchaeota and they are members of the prokaryotic domain Archaea. They thrive best in extremely saline habitats with salt concentrations of 2–5 mol L–1 NaCl, and thus under conditions

Production of Polyhydroxyalkanoates in Unsterilized Hyper-Saline Medium by Halophiles Using Waste Silkworm Excrement as Carbon Source

Molecules, 2021
The chlorophyll ethanol-extracted silkworm excrement was hardly biologically reused or fermented by most microorganisms. However, partial extremely environmental halophiles were reported to be able to utilize a variety of inexpensive carbon sources to ...

Cellulose metabolism in halo(natrono)archaea: a comparative genomics study

Frontiers in Microbiology, 2023
Extremely halophilic archaea are one of the principal microbial community components in hypersaline environments. The majority of cultivated haloarchaea are aerobic heterotrophs using peptides or simple sugars as carbon and energy sources.

Glycerol metabolism of haloarchaea [PDF]

Environmental Microbiology, 2016
Summary Haloarchaea are heterotrophic members of the Archaea that thrive in hypersaline environments, often feeding off the glycerol that is produced as an osmolyte by eucaryotic Dunaliella during primary production.
