Novel viruses of Haloquadratum walsbyi expand the known archaeal virosphere of hypersaline environments. [PDF]
Abstract Solar salterns represent unique systems with low diversity microbial communities that serve as an excellent model for studying the evolution and ecology of archaeal viruses and the interactions with their hosts. This is particularly relevant for the extremely abundant “square” archaeon Haloquadratum walsbyi, for which isolated ...

Determining virus-host interactions and glycerol metabolism profiles in geographically diverse solar salterns with metagenomics [PDF]
Solar salterns are excellent model ecosystems for studying virus-microbial interactions because of their low microbial diversity, environmental stability, and high viral density.

The complete genomes of four Halobacterium salinarum strains were compared in detail. Two strains (91‐R6T and 63‐R2) were isolated in 1934 by Lochhead from cow and buffalo hides. From the results of these comparisons, we conclude that strain 63‐R2 is the immediate ancestor of the two, widely used laboratory strains NRC‐1 and R1.

Scientific novelty beyond the experiment
Practical experiments drive important scientific discoveries in biology, but theory‐based research studies also contribute novel—sometimes paradigm‐changing—findings. Here, we appraise the roles of theory‐based approaches focusing on the experiment‐dominated wet‐biology research areas of microbiology. Theory‐based studies can transcend barriers imposed

Abstract Environmental tolerance curves, representing absolute fitness against the environment, are an empirical assessment of the fundamental niche, and emerge from the phenotypic plasticity of underlying phenotypic traits. Dynamic plastic responses of these traits can lead to acclimation effects, whereby recent past environments impact current ...

Summary Soda‐saline lakes are polyextreme environments inhabited by many haloalkaliphiles, including one of the most abundant Spiribacter species. However, its mechanisms of adaptation are not ecophysiologically characterized. Based on a large‐scale cultivation strategy, we obtained a representative isolate of this Spiribacter species whose relative ...

Extremely halophilic archaeal communities are resilient to short‐term entombment in halite
Summary Some haloarchaea avoid the harsh conditions present in evaporating brines by entombment in brine inclusions within forming halite crystals, where a subset of haloarchaea survives over geological time. However, shifts in the community structure of halite‐entombed archaeal communities remain poorly understood.

Evaluating the potential for Haloarchaea to serve as ice nucleating particles [PDF]
Aerosols play a crucial role in cloud formation. Biologically derived materials from bacteria, fungi, pollen, lichen, viruses, algae, and diatoms can serve as ice nucleating particles (INPs), some of which initiate glaciation in clouds at relatively warm

A moderate halophile Yangia sp. ND199, isolated from a mangrove sample in Northern Vietnam and known to accumulate polyhydroxyalkanoates (PHAs), was shown to have the potential for producing also exopolysaccharides (EPSs). Genome sequence analysis of the closely related Yangia sp.

Lipids of the ultra‐thin square halophilic archaeon Haloquadratum walsbyi [PDF]
The lipid composition of the extremely halophilic archaeon Haloquadratum walsbyi was investigated by thin‐layer chromatography and electrospray ionization‐mass spectrometry. The analysis of neutral lipids showed the presence of vitamin MK‐8, squalene, carotene, bacterioruberin and several retinal isomers.
