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.

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.

Production of Polyhydroxyalkanoates in Unsterilized Hyper-Saline Medium by Halophiles Using Waste Silkworm Excrement as Carbon Source

Molecules, 2021
The chlorophyll ethanol-extracted silkworm excrement was hardly biologically reused or fermented by most microorganisms. However, partial extremely environmental halophiles were reported to be able to utilize a variety of inexpensive carbon sources to ...

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.

Nitrogen metabolism in haloarchaea [PDF]

Saline Systems, 2008
The nitrogen cycle (N-cycle), principally supported by prokaryotes, involves different redox reactions mainly focused on assimilatory purposes or respiratory processes for energy conservation. As the N-cycle has important environmental implications, this biogeochemical cycle has become a major research topic during the last few years. However, although

Searching for species in haloarchaea [PDF]

Proceedings of the National Academy of Sciences, 2007
Prokaryotic (bacterial and archaeal) species definitions and the biological concepts that underpin them entail clustering (cohesion) among individuals, in terms of genome content and gene sequence similarity. Homologous recombination can maintain gene sequence similarity within, while permitting divergence between, clusters and is thus the

Glycerol metabolism of haloarchaea [PDF]

Environmental Microbiology, 2016
Summary Haloarchaea are heterotrophic members of the Archaea that thrive in hypersaline environments, often feeding off the glycerol that is produced as an osmolyte by eucaryotic Dunaliella during primary production.

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.
