Establishment of a Halophilic Bloom in a Sterile and Isolated Hypersaline Mesocosm
Microorganisms, 2023 Extreme environments, including hypersaline pools, often serve as biogeographical islands. Putative colonizers would need to survive transport across potentially vast distances of inhospitable terrain.

The human gut archaeome: identification of diverse haloarchaea in Korean subjects
Microbiome, 2020 Background Archaea are one of the least-studied members of the gut-dwelling autochthonous microbiota. Few studies have reported the dominance of methanogens in the archaeal microbiome (archaeome) of the human gut, although limited information regarding ...

Phylogenomics of Haloarchaea: The Controversy of the Genera Natrinema-Haloterrigena
Frontiers in Microbiology, 2021 The haloarchaeal genera Natrinema and Haloterrigena were described almost simultaneously by two different research groups and some strains studied separately were described as different species of these genera.

New Halonotius Species Provide Genomics-Based Insights Into Cobalamin Synthesis in Haloarchaea [PDF]
, 2019 Hypersaline aquatic and terrestrial ecosystems display a cosmopolitan distribution. These environments teem with microbes and harbor a plethora of prokaryotic lineages that evaded ecological characterization due to the prior inability to cultivate them ...

Cellular and Genomic Properties of Haloferax gibbonsii LR2-5, the Host of Euryarchaeal Virus HFTV1
Frontiers in Microbiology, 2021 Hypersaline environments are the source of many viruses infecting different species of halophilic euryarchaea. Information on infection mechanisms of archaeal viruses is scarce, due to the lack of genetically accessible virus–host models. Recently, a new

Geochemical constraints on the Hadean environment from mineral fingerprints of prokaryotes [PDF]
, 2017 The environmental conditions on the Earth before 4 billion years ago are highly uncertain, largely because of the lack of a substantial rock record from this period.

How Do Haloarchaea Synthesize Aromatic Amino Acids?
PLoS ONE, 2014 Genomic analysis of H. salinarum indicated that the de novo pathway for aromatic amino acid (AroAA) biosynthesis does not follow the classical pathway but begins from non-classical precursors, as is the case for M. jannaschii. The first two steps in the pathway were predicted to be carried out by genes OE1472F and OE1475F, while the 3rd step follows ...

Nanohaloarchaea as beneficiaries of xylan degradation by haloarchaea
Microbial Biotechnology, 2023 Abstract Climate change, desertification, salinisation of soils and the changing hydrology of the Earth are creating or modifying microbial habitats at all scales including the oceans, saline groundwaters and brine lakes.

Journal of Mazandaran University of Medical Sciences, 2022 Background and purpose: Dental caries is one of the most common bacterial diseases in childhood. Using proper dentifrice is suggested to reduce the incidence of this disease. The aim of this study was to investigate the antimicrobial effects of different

Biology, 2021 Alpha-amylases are a large family of α,1-4-endo-glycosyl hydrolases distributed in all kingdoms of life. The need for poly-extremotolerant amylases encouraged their search in extreme environments, where archaea become ideal candidates to provide new ...
