Novel Extended Tetraether Lipids Found in a High‐CO2 Geyser

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Characterisation of the archaeal lipidome of the CO2‐rich subsurface aquifer of the Geyser Andernach reveals novel extended tetraether lipids analogous to extended archaeols, likely produced by Candidatus Altiarchaeum, and potentially functioning as a membrane adaptation strategy to nutrient‐deprived conditions.

Optimization of Growth and Carotenoid Production by Haloferax mediterranei Using Response Surface Methodology

Marine Drugs, 2018
Haloferax mediterranei produces C50 carotenoids that have strong antioxidant properties. The response surface methodology (RSM) tool helps to accurately analyze the most suitable conditions to maximize C50 carotenoids production by haloarchaea.

Study on the production of high 3HV content PHBV via an open fermentation with waste silkworm excrement as the carbon source by the haloarchaeon Haloferax mediterranei

Frontiers in Microbiology, 2022
Silkworm excrement is hard to be degraded or bio-utilized by environmental microorganisms due to its high content of heavy metals and antimicrobial biomacromolecules in mulberry leaves. In traditional Chinese silk industry, the silkworm excrement results

Evolution of lysine and arginine biosynthesis revealed by substrate specificity of lysine biosynthetic enzymes in Thermus thermophilus

The FEBS Journal, Volume 293, Issue 6, Page 1727-1740, March 2026.
Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.

Characterization and Functional Evaluation of Carotenoids From Haloarcula rubripromontorii BS2

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
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 ...

A Small RNA Is Linking CRISPR–Cas and Zinc Transport

Frontiers in Molecular Biosciences, 2021
The function and mode of action of small regulatory RNAs is currently still understudied in archaea. In the halophilic archaeon Haloferax volcanii, a plethora of sRNAs have been identified; however, in-depth functional analysis is missing for most of ...

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

Bacteriocins as a Promising Antimicrobial Strategy Against Multidrug‐Resistant Pathogens: Mechanisms of Action, Applications in Human and Animal Health, and the Food Industry

BioMed Research International, Volume 2026, Issue 1, 2026.
The global rise of antimicrobial resistance has significantly increased the difficulty treating infectious agents, creating an urgent need for alternative therapeutic strategies. In this context, bacteriocins have emerged as a promising solution, offering a potential alternative to conventional antibacterial therapies.

The degradation of glycosaminoglycans by haloarchaea is apparently a common feature in hypersaline habitats worldwide

Frontiers in Microbiology
Recent extensive studies of the functional diversity of extremely halophilic archaea (haloarchaea) have significantly altered the long-held view of this unique group of extremophiles as halophilic heterotrophs utilizing either rich mixtures of amino ...
