Salactin, a dynamically unstable actin homolog in Haloarchaea [PDF]

mBio, 2023
ABSTRACT Across the domains of life, actin homologs are integral components of many essential processes, such as DNA segregation, cell division, and cell shape determination. Archaeal genomes, like those of bacteria and eukaryotes, also encode actin homologs, but much less is known about these proteins’

Discovery of anaerobic lithoheterotrophic haloarchaea, ubiquitous in hypersaline habitats [PDF]

The ISME Journal, 2017
Abstract Hypersaline anoxic habitats harbour numerous novel uncultured archaea whose metabolic and ecological roles remain to be elucidated. Until recently, it was believed that energy generation via dissimilatory reduction of sulfur compounds is not functional at salt saturation conditions.

Polyploidy in haloarchaea: advantages for growth and survival [PDF]

Frontiers in Microbiology, 2014
The investigated haloarchaeal species, Halobacterium salinarum, Haloferax mediterranei, and H. volcanii, have all been shown to be polyploid. They contain several replicons that have independent copy number regulation, and most have a higher copy number during exponential growth phase than in stationary phase.

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.

Haloarchaea as Promising Chassis to Green Chemistry. [PDF]

Microorganisms
Climate change and the scarcity of primary resources are driving the development of new, more renewable and environmentally friendly industrial processes. As part of this green chemistry approach, extremozymes (extreme microbial enzymes) can be used to replace all or part of the chemical synthesis stages of traditional industrial processes. At present,

Nitrogen metabolism in haloarchaea [PDF]

Saline Systems, 2008
The nitrogen cycle (N-cycle), principally supported by prokaryotes, involves different redox reactions mainly focused on assimilatory purposes or respiratory processes for energy conservation. As the N-cycle has important environmental implications, this biogeochemical cycle has become a major research topic during the last few years. However, although

Mechanisms of Metal Resistance and Homeostasis in Haloarchaea [PDF]

Archaea, 2013
Haloarchaea are the predominant microflora of hypersaline econiches such as solar salterns, soda lakes, and estuaries where the salinity ranges from 35 to 400 ppt. Econiches like estuaries and solar crystallizer ponds may contain high concentrations of metals since they serve as ecological sinks for metal pollution and also as effective traps for river

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 ...
