Searching for species in haloarchaea [PDF]
Proceedings of the National Academy of Sciences, 2007 Prokaryotic (bacterial and archaeal) species definitions and the biological concepts that underpin them entail clustering (cohesion) among individuals, in terms of genome content and gene sequence similarity. Homologous recombination can maintain gene sequence similarity within, while permitting divergence between, clusters and is thus the

Growth Phase Dependent Cell Shape of Haloarcula
Microorganisms, 2021 Several haloarchaea are reported to be pleomorphic, while others exhibit remarkable shapes, such as squares. Recently, Haloferax volcanii was found to alter its morphology during growth.

Sizing chromosomes and megaplasmids in haloarchaea [PDF]
Microbiology, 1996 PFGE was used for the genomic analysis of different species and strains belonging to four out of the six recognized haloarchaeal (halobacterial) genera. All of them were found to carry one chromosome from 1.8-3 Mb, and usually several, but at least one, large plasmids of approximately 90-680 kb, which were detected in supercoiled and linear forms. From

Responses of Haloarchaea to Simulated Microgravity [PDF]
Astrobiology, 2011 Various effects of microgravity on prokaryotes have been recognized in recent years, with the focus on studies of pathogenic bacteria. No archaea have been investigated yet with respect to their responses to microgravity. For exposure experiments on spacecrafts or on the International Space Station, halophilic archaea (haloarchaea) are usually embedded

Antioxidants, 2023 The production of reactive oxygen species (ROS) plays an important role in the progression of many inflammatory diseases. The search for antioxidants with the ability for scavenging free radicals from the body cells that reduce oxidative damage is ...

Frontiers in Microbiology, 2016 Haloarchaea are salt-loving halophilic microorganism’s that inhabit marine environments, sea water, salterns, and lakes. The resistance of haloarchaea to physical extremities that challenge organismic survival is ubiquitous.

F1000Research, 2014 The halophilic archaea (haloarchaea) live in saline environments, which are found across the globe. In addition to salinity, these niches can be quite dynamic and experience extreme conditions such as low oxygen content, radiation (gamma and UV), pH and

Bioengineering, 2019 Haloarchaea, the extremely halophilic branch of the Archaea domain, encompass a steadily increasing number of genera and associated species which accumulate polyhydroxyalkanoate biopolyesters in their cytoplasm.
