Bacterioruberin from Haloarchaea plus dexamethasone in ultra-small macrophage-targeted nanoparticles as potential intestinal repairing agent [PDF]

Colloids and Surfaces B: Biointerfaces, 2020
Oral administration of antioxidant and anti-inflammatory drugs have the potential to improve the current therapy of inflammatory bowel disease. Success of oral treatments, however, depends on the capacity of drugs to remain structurally stable along the gastrointestinal tract, and on the feasibility of accessing the target cells.

Adaptation, Ecology, and Evolution of the Halophilic Stromatolite Archaeon Halococcus hamelinensis Inferred through Genome Analyses

Archaea, Volume 2015, Issue 1, 2015., 2015
Halococcus hamelinensis was the first archaeon isolated from stromatolites. These geomicrobial ecosystems are thought to be some of the earliest known on Earth, yet, despite their evolutionary significance, the role of Archaea in these systems is still not well understood. Detailed here is the genome sequencing and analysis of an archaeon isolated from

Recycling of Waste Streams of the Biotechnological Poly(hydroxyalkanoate) Production by Haloferax mediterranei on Whey

International Journal of Polymer Science, Volume 2015, Issue 1, 2015., 2015
For manufacturing “bioplastics” such as poly(hydroxyalkanoates) (PHA), the combination of utilization of inexpensive carbon sources with the application of robust microbial production strains is considered a decisive step to make this process more cost‐efficient and sustainable.

Colorful World of Microbes: Carotenoids and Their Applications

Advances in Biology, Volume 2014, Issue 1, 2014., 2014
Microbial cells accumulate pigments under certain culture conditions, which have very important industrial applications. Microorganisms can serve as sources of carotenoids, the most widespread group of naturally occurring pigments. More than 750 structurally different yellow, orange, and red colored molecules are found in both eukaryotes and ...

Archaeal Production of Polyhydroxyalkanoate (PHA) Co‐ and Terpolyesters from Biodiesel Industry‐Derived By‐Products

Archaea, Volume 2013, Issue 1, 2013., 2013
The archaeon Haloferax mediterranei was selected for production of PHA co‐ and terpolyesters using inexpensive crude glycerol phase (CGP) from biodiesel production as carbon source. CGP was assessed by comparison with the application of pure glycerol. Applying pure glycerol, a copolyester with a molar fraction of 3‐hydroxybutyrate (3HB) of 0.90 mol/mol

Lipids of Archaeal Viruses

Archaea, Volume 2012, Issue 1, 2012., 2012
Archaeal viruses represent one of the least known territory of the viral universe and even less is known about their lipids. Based on the current knowledge, however, it seems that, as in other viruses, archaeal viral lipids are mostly incorporated into membranes that reside either as outer envelopes or membranes inside an icosahedral capsid.

Archaea Signal Recognition Particle Shows the Way

Archaea, Volume 2010, Issue 1, 2010., 2010
Archaea SRP is composed of an SRP RNA molecule and two bound proteins named SRP19 and SRP54. Regulated by the binding and hydrolysis of guanosine triphosphates, the RNA‐bound SRP54 protein transiently associates not only with the hydrophobic signal sequence as it emerges from the ribosomal exit tunnel, but also interacts with the membrane‐associated ...

Lipids of the ultra‐thin square halophilic archaeon Haloquadratum walsbyi

Archaea, Volume 2, Issue 3, Page 177-183, 2008., 2008
The lipid composition of the extremely halophilic archaeon Haloquadratum walsbyi was investigated by thin‐layer chromatography and electrospray ionization‐mass spectrometry. The analysis of neutral lipids showed the presence of vitamin MK‐8, squalene, carotene, bacterioruberin and several retinal isomers.

In Situ Study of the Function of Bacterioruberin in the Dual‐Chromophore Photoreceptor Archaerhodopsin‐4 [PDF]

Angewandte Chemie International Edition, 2018
AbstractWhile certain archaeal ion pumps have been shown to contain two chromophores, retinal and the carotenoid bacterioruberin, the functions of bacterioruberin have not been well explored. To address this research gap, recombinant archaerhodopsin‐4 (aR4), either with retinal only or with both retinal and bacterioruberin chromophores, was ...

Antioxidative and chaperone‐like activities of a bacterioruberin‐rich extract: An innovative approach to protect the skin proteome

International Journal of Cosmetic Science, EarlyView.
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.
