The genome of the square archaeon
BMC Genomics, 2006 Background The square halophilic archaeon Haloquadratum walsbyi dominates NaCl-saturated and MgCl2 enriched aquatic ecosystems, which imposes a serious desiccation stress, caused by the extremely low water activity.

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 ...

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 ...

Archaea, Volume 2015, Issue 1, 2015., 2015 Hypersaline systems near salt saturation levels represent an extreme environment, in which organisms grow and survive near the limits of life. One of the abundant members of the microbial communities in hypersaline systems is the square archaeon, Haloquadratum walsbyi.

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 ...

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 ...

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 ...

PH1: An Archaeovirus of Haloarcula hispanica Related to SH1 and HHIV‐2
Archaea, Volume 2013, Issue 1, 2013., 2013 Halovirus PH1 infects Haloarcula hispanica and was isolated from an Australian salt lake. The burst size in single‐step growth conditions was 50–100 PFU/cell, but cell density did not decrease until well after the rise (4–6 hr p.i.), indicating that the virus could exit without cell lysis.

Frontiers in Microbiology, 2018 Hypersaline environments represent some of the most challenging settings for life on Earth. Extremely halophilic microorganisms have been selected to colonize and thrive in these extreme environments by virtue of a broad spectrum of adaptations to ...

Dihydroxyacetone metabolism in Haloferax volcanii
Frontiers in Microbiology, 2013 Dihydroxyacetone (DHA) is a ketose sugar that can be produced by oxidizing glycerol. DHA in the environment is taken up and phosphorylated to DHA-phosphate by glycerol kinase or DHA kinase.
