A tripartite comparison of Archaea phylogeny and taxonomy at and above the rank order is reported: (1) the whole-genome-based and alignment-free CVTree using 179 genomes; (2) the 16S rRNA analysis exemplified by the All-Species Living Tree with 366 ...

An identity card for sabkha dolomite
An ‘identity card’ for modern sabkha dolomite from Qatar reveals its mineralogical, geochemical and microbial characteristics. This integrated dataset provides a benchmark for recognising similar dolomites in the rock record and for calibrating paleoenvironmental proxies used in climate and biosignature studies.

Metagenome Sequencing of Prokaryotic Microbiota from Two Hypersaline Soils of the Odiel Salt Marshes in Huelva, Southwestern Spain [PDF]
Two 454 shotgun metagenomes were sequenced from hypersaline soil samples collected in the Odiel salt marsh area in Huelva, southwestern Spain. Analysis of contigs and 16S rRNA-related sequences showed that Halobacteria, Balneolaeota, and Bacteroidetes ...

Inference of expanded Lrp-like feast/famine transcription factor targets in a non-model organism using protein structure-based prediction. [PDF]
Widespread microbial genome sequencing presents an opportunity to understand the gene regulatory networks of non-model organisms. This requires knowledge of the binding sites for transcription factors whose DNA-binding properties are unknown or difficult

The ecology and taxonomy of halobacteria [PDF]
Abstract Archaebacterial halophiles dominate naturally occurring brines as the concentration of salts approaches saturation. Although only 4 genera of these bacteria have been recognised (Halobacterium, Halococcus, Natronobacterium, Natronococcus), chemotaxonomic studies indicate that there are 4 or 5 additional distinct groups.

Characterization and Functional Evaluation of Carotenoids From Haloarcula rubripromontorii BS2
Fractionation and comprehensive characterization of C50 carotenoids from Haloarcula rubripromontorii BS2, identified all‐trans bacterioruberin as the predominant isomer. The haloarchaeal carotenoid exhibited strong antioxidant activity, photostability in oil and was biocompatible with human keratinocytes, highlighting their potential as sustainable ...

Diversity of FAAL enzymes and prediction of their substrate specificity using FAALPred
Abstract FAALs (fatty acyl‐AMP ligases) recruit and incorporate fatty acids during the biosynthesis of secondary metabolites. Their diversity, distribution, and substrate specificity remain poorly understood, which limits functional predictions from sequence data.

Genotypic and Lipid Analyses of Strains From the Archaeal Genus Halorubrum Reveal Insights Into Their Taxonomy, Divergence, and Population Structure [PDF]
To gain a better understanding of how divergence occurs, and how taxonomy can benefit from studying natural populations, we isolated and examined 25 closely related Halorubrum strains obtained from different hypersaline communities and compared them to ...

Genomic variation and biogeography of Antarctic haloarchaea
Background The genomes of halophilic archaea (haloarchaea) often comprise multiple replicons. Genomic variation in haloarchaea has been linked to viral infection pressure and, in the case of Antarctic communities, can be caused by intergenera gene ...
