Life in the brine of Lunenburg, Germany: unveiling microorganisms associated with Zechstein salt deposits [PDF]

Frontiers in Microbiology
IntroductionThe presence of hypersaline brines on other planets and moons in the inner and outer Solar System has been well established. Hence, any theory of life on other planets must consider microorganisms adapted to high salt concentrations.

Antioxidative and chaperone-like activities of a bacterioruberin-rich extract: An innovative approach to protect the skin proteome. [PDF]

Int J Cosmet Sci
The bacteriorubin‐rich extract of Arthrobacter agilis has high antioxidative properties, protecting proteins against oxidative stress and preventing their carbonylation. It also protects proteins against saline and heat stresses, suggesting a dual mode of action including antioxidant and chaperone‐like activities.

The Antitumour Mechanisms of Carotenoids: A Comprehensive Review [PDF]

Antioxidants
Carotenoids, known for their antioxidant properties, have garnered significant attention for their potential antitumour activities. This comprehensive review aims to elucidate the diverse mechanisms by which carotenoids exert antitumour effects, focusing

Elucidating metabolic pathways through genomic analysis in highly heavy metal-resistant Halobacterium salinarum strains. [PDF]

Heliyon
The annotated and predicted genomes of five archaeal strains (AS1, AS2, AS8, AS11 and AS19), isolated from Sfax solar saltern sediments (Tunisia) and affiliated with Halobacterium salinarum, were performed by RAST webserver (Rapid Annotation using ...

Nebulized Bacterioruberin/Astaxanthin-Loaded Nanovesicles: Antitumoral Activity and Beyond. [PDF]

Int J Mol Sci
The membranes of halophilic archaea are a source of novel biomaterials, mainly of isoprenoid nature, with therapeutic properties practically unraveled. Here, we explored the antitumoral activity of neutral archaeolipids (NAs, such as bacterioruberin, astaxanthin, and dihydrosqualene) present in the total archaeolipids (TAs) (a fraction from the first ...

Microbial Bacterioruberin: A Comprehensive Review. [PDF]

Indian J Microbiol
Bacterioruberin (BR) is a fat-soluble, dipolar, reddish pigment predominantly found in halophilic archaea. BR is a rare C50 carotenoid from the xanthophyll family, and it has been extensively studied for its potent antioxidant properties, such as its ability to protect cells from oxidative stress.

The Role of Structural Order in the Mechanism of Charge Transport across Tunnel Junctions with Various Iron‐Storing Proteins

Small, Volume 18, Issue 42, October 20, 2022., 2022
Large proteins support remarkably high charge transport rates, but the factors that influence the charge transport mechanism are still unclear. This work shows the importance of structural order: ordered structures support coherent tunnelling pathways while charges “hop” across disordered structures.
