A New Era for Using Natural Pigments: The Case of the C₅₀ Carotenoid Called Bacterioruberin. [PDF]

Biotechnol Appl Biochem
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Characterization and Functional Evaluation of Carotenoids From Haloarcula rubripromontorii BS2. [PDF]

Microbiologyopen
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 ...

Toxicity Assessment and Bioremediation of Deep Eutectic Solvents by Haloferax mediterranei: A Step toward Sustainable Circular Chemistry. [PDF]

ChemSusChem
The toxicity and biodegradability of deep eutectic solvents (DESs) can be evaluated using Haloferax mediterranei as a novel model organism. The haloarchaeon metabolizes specific DES components, highlighting its potential for DES bioremediation. These findings support the use of H.

Cellulose metabolism in halo(natrono)archaea: a comparative genomics study

Frontiers in Microbiology, 2023
Extremely halophilic archaea are one of the principal microbial community components in hypersaline environments. The majority of cultivated haloarchaea are aerobic heterotrophs using peptides or simple sugars as carbon and energy sources.

Decoding the Chemical Language of Ribosomally Synthesized and Post-Translationally Modified Peptides from the Untapped Archaea Domain. [PDF]

Angew Chem Int Ed Engl
Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

Growth Phase Dependent Cell Shape of Haloarcula

Microorganisms, 2021
Several haloarchaea are reported to be pleomorphic, while others exhibit remarkable shapes, such as squares. Recently, Haloferax volcanii was found to alter its morphology during growth.

Selective enrichment on a wide polysaccharide spectrum allowed isolation of novel metabolic and taxonomic groups of haloarchaea from hypersaline lakes

Frontiers in Microbiology, 2022
Extremely halophilic archaea (haloarchaea) of the class Halobacteria is a dominant group of aerobic heterotrophic prokaryotic communities in salt-saturated habitats, such as salt lakes and solar salterns.

Up-Regulation of the Nrf2/HO-1 Antioxidant Pathway in Macrophages by an Extract from a New Halophilic Archaea Isolated in Odiel Saltworks

Antioxidants, 2023
The production of reactive oxygen species (ROS) plays an important role in the progression of many inflammatory diseases. The search for antioxidants with the ability for scavenging free radicals from the body cells that reduce oxidative damage is ...

Antimicrobial Activity and Mechanism of inhibition of Silver Nanoparticles against Extreme Halophilic Archaea

Frontiers in Microbiology, 2016
Haloarchaea are salt-loving halophilic microorganism’s that inhabit marine environments, sea water, salterns, and lakes. The resistance of haloarchaea to physical extremities that challenge organismic survival is ubiquitous.
