Anaerobic growth of halobacteria.

open access: yesProceedings of the National Academy of Sciences, 1980
An energy-transducing pathway in halobacteria is described. Arginine mediates substrate level phosphorylation and allows the cells to grow anaerobically. Bacteriorhodopsin plus light can function as an alternative energy source under these conditions, provided the cells contain the pigment when transferred to the anaerobic environment.

Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery

open access: yesMolecular Microbiology, EarlyView.
The Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.

New Insights Into the Polar Lipid Composition of Extremely Halo(alkali)philic Euryarchaea From Hypersaline Lakes

open access: yesFrontiers in Microbiology, 2019
We analyzed the polar membrane lipids of 13 strains of halo(alkali)philic euryarchaea from hypersaline lakes. Nine belong to the class Halobacteria, representing two functional groups: aerobic polysaccharide utilizers and sulfur-respiring anaerobes.

Current strategies to enhance the target efficiency of advanced multifunctional ultrasound contrast agents in ischemic diseases

open access: yesInterdisciplinary Medicine, Volume 4, Issue 5, September 2026.
The graphical abstract outlines a novel multifunctional ultrasound contrast agent for the diagnosis and treatment of ischemic diseases, along with innovative strategies to enhance its targeting efficiency. Abstract Ischemic diseases, such as myocardial infarction, stroke, and peripheral ischemia, are leading causes of death and disability worldwide ...

Differences in lateral gene transfer in hypersaline versus thermal environments

open access: yesBMC Evolutionary Biology, 2011
Background The role of lateral gene transfer (LGT) in the evolution of microorganisms is only beginning to be understood. While most LGT events occur between closely related individuals, inter-phylum and inter-domain LGT events are not uncommon.

Accumulation of Poly (β-Hydroxybutyrate) by Halobacteria [PDF]

open access: yesApplied and Environmental Microbiology, 1986
Some species of extremely halophilic archaebacteria, Halobacteriaceae , have been shown to accumulate large amounts of poly (β-hydroxybutyrate) under conditions of nitrogen limitation and abundant carbon source.

Quaternary structures of Streptococcus pneumoniae nucleoside diphosphate kinase: From hexamers to supramolecular assemblies

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract The nucleoside diphosphate kinase (NDK) is a key enzyme that controls the balance of nucleotide pools in all living organisms. Beyond this fundamental role, NDKs exert pleiotropic effects in many cellular processes, including cell development, signal transduction, differentiation, tumor metastasis, and gene expression. The quaternary structure

Towards the Understanding of the Function of Lanthipeptide and TOMM-Related Genes in Haloferax mediterranei

open access: yesBiology, 2023
Research on secondary metabolites produced by Archaea such as ribosomally synthesized and post-translationally modified peptides (RiPPs) is limited. The genome of Haloferax mediterranei ATCC 33500 encodes lanthipeptide synthetases (medM1, medM2, and ...

Atmospheric Microbial Transport to Antarctica and Its Ecological Implications: A Systematic Review

open access: yesEnvironmental Microbiology, Volume 28, Issue 9, September 2026.
Atmospheric transport to Antarctica operates via long‐range advection, marine aerosolization, and local resuspension, acting as a strict ecological filter. This selective barrier could actively shape local ecosystems by seeding them with functionally distinct, stress‐adapted microbial pioneers capable of surviving extreme conditions.

Metagenomic Insights Into Red Sea Biodiversity Across the Web of Life

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Deep‐sequencing shotgun metagenomics of Red Sea benthic sediments reveals biodiversity across the web of life, from viruses to animals. Despite the strong dominance of prokaryotic DNA, low‐abundance eukaryotic reads capture broad taxonomic diversity. Open‐ocean communities are primarily structured by depth, whereas coastal eukaryotic communities follow
