MicrobiologyOpen, Volume 8, Issue 9, September 2019., 2019 Cyclic di‐adenylate monophosphate (c‐di‐AMP) is an essential second messenger in bacteria, where it was demonstrated to have a central function in cellular osmoregulation. For archaea, currently little information on second messengers is available. This study proves that c‐di‐AMP is present in vivo in the archaeon Haloferax volcanii and demonstrates ...

Archaea, Volume 2017, Issue 1, 2017., 2017 A 1.1 × 106 Da acidic exopolysaccharide (EPS) was purified from an extremely halophilic archaeon Haloarcula hispanica ATCC33960 with a production of 30 mg L−1 when grown in AS‐168 medium, which mainly composed of mannose and galactose with a small amount of glucose in a molar ratio of 55.9 : 43.2 : 0.9.

A Manual Curation Strategy to Improve Genome Annotation: Application to a Set of Haloarchael Genomes
Life, 2015 Genome annotation errors are a persistent problem that impede research in the biosciences. A manual curation effort is described that attempts to produce high-quality genome annotations for a set of haloarchaeal genomes (Halobacterium salinarum and Hbt ...

Archaea, Volume 2016, Issue 1, 2016., 2016 Recent studies on archaeal diversity in few salterns have revealed heterogeneity between sites and unique structures of separate places that hinder drawing of generalized conclusions. Investigations on the archaeal community composition in P18, the biggest crystallizer pond in Pomorie salterns (PS) (34% salinity), demonstrated unusually high number of ...

A Spotlight on Archaea in Humans, Livestock and Poultry: A Review
Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.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 ...

Marine Drugs, 2018 The solar salterns located in the Odiel marshlands, in southwest Spain, are an excellent example of a hypersaline environment inhabited by microbial populations specialized in thriving under conditions of high salinity, which remains poorly explored ...

Diversity of the DNA Replication System in the Archaea Domain
Archaea, Volume 2014, Issue 1, 2014., 2014 The precise and timely duplication of the genome is essential for cellular life. It is achieved by DNA replication, a complex process that is conserved among the three domains of life. Even though the cellular structure of archaea closely resembles that of bacteria, the information processing machinery of archaea is evolutionarily more closely related ...

Structural and Functional Studies of a Newly Grouped Haloquadratum walsbyi Bacteriorhodopsin Reveal the Acid-resistant Light-driven Proton Pumping Activity [PDF]
Journal of Biological Chemistry, 2015 Retinal bound light-driven proton pumps are widespread in eukaryotic and prokaryotic organisms. Among these pumps, bacteriorhodopsin (BR) proteins cooperate with ATP synthase to convert captured solar energy into a biologically consumable form, ATP. In an acidic environment or when pumped-out protons accumulate in the extracellular region, the maximum ...

Virus‐Host and CRISPR Dynamics in Archaea‐Dominated Hypersaline Lake Tyrrell, Victoria, Australia
Archaea, Volume 2013, Issue 1, 2013., 2013 The study of natural archaeal assemblages requires community context, namely, a concurrent assessment of the dynamics of archaeal, bacterial, and viral populations. Here, we use filter size‐resolved metagenomic analyses to report the dynamics of 101 archaeal and bacterial OTUs and 140 viral populations across 17 samples collected over different ...

Development of an immunoFET biosensor for the detection of biotinylated PCR product
Heliyon, 2016 ImmunoFET (IMFET) biosensor is a simple platform for the detection of biotinylated products of polymerase chain reaction (PCR). Construction of the IMFET biosensor started with adsorption of 1.5 mg/mL of protein A (PA) onto the insulated gate surface of ...
