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

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.

Optimized Plaque Assay for Detecting Chronically Infecting Viruses of Haloarchaea

bioRxiv
Archaeal viruses predominantly exhibit a chronic lifestyle, where viral particles are released without causing host cell death. Therefore, conventional plaque assays, which are well-suited for identifying lytic viruses, usually fail to detect chronically

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

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 ...

An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
In an era marked by environmental challenges and the proliferation of misinformation, the fusion of art and science is a strategy to promote public understanding and appreciation of complex scientific phenomena. We illustrate how the use of extremophiles offers novel avenues for artistic exploration and emphasise the benefits of such interdisciplinary ...

Hundreds of novel composite genes and chimeric genes with bacterial origins contributed to haloarchaeal evolution

Genome Biology, 2018
Background Haloarchaea, a major group of archaea, are able to metabolize sugars and to live in oxygenated salty environments. Their physiology and lifestyle strongly contrast with that of their archaeal ancestors.

Improved GFP Variants to Study Gene Expression in Haloarchaea

Frontiers in Microbiology, 2019
The study of promoter activities in haloarchaea is carried out exclusively using enzymes as reporters. An alternative reporter is the gene encoding the Green Fluorescent Protein (GFP), a simple and fast tool for investigating promoter strengths. However,
