An octameric prokaryotic glutamine synthetase from the haloarchaeonHaloferax mediterranei [PDF]
The glutamine synthetase (EC 6.3.1.2) from the haloarchaeon Haloferax mediterranei has been purified and characterized in order to understand the ammonium assimilation in haloarchaea. Based on sodium dodecyl sulfate polyacrylamide gel electrophoresis and gel-filtration chromatography, the enzyme consists of eight subunits of 51.7 kDa, suggesting that ...

Understanding the tolerance of halophilic archaea to stress landscapes
The tolerance responses of nine Haloarchaea species were analysed under 70 different conditions, including various salinities, temperatures, oxidative stress and the presence of metals. In general, all characterised species tolerated heavy metals, with a particularly striking tolerance to lithium. These results highlight the relevance of Haloarchaea in

Semi‐continuous non‐sterile production of medium chain‐length polyhydroxyalkanoates from fatty acids
Abstract Medium chain‐length polyhydroxyalkanoates (mcl‐PHAs) are efficiently synthesized from fatty acids. It was hypothesized that under non‐axenic conditions, the anti‐microbial properties of fatty acids would reduce growth of microbial competitors and allow Pseudomonas putida LS46 to dominate the population resulting in non‐sterile mcl‐PHA ...

A comprehensive analysis of the importance of translation initiation factors for Haloferax volcanii applying deletion and conditional depletion mutants [PDF]
Translation is an important step in gene expression. The initiation of translation is phylogenetically diverse, since currently five different initiation mechanisms are known.

Haloarchaea and the Formation of Gas Vesicles
Halophilic Archaea (Haloarchaea) thrive in salterns containing sodium chloride concentrations up to saturation. Many Haloarchaea possess genes encoding gas vesicles, but only a few species, such as Halobacterium salinarum and Haloferax mediterranei ...

Bacillus licheniformis AZU‐A5 produced polyhydroxyalkanoates (PHAs) using cheese whey, achieving a yield of 1.75 g L−1 through Plackett–Burman design and specific factor optimization. Spectroscopy, chromatography, and thermal analysis confirmed the PHA as poly(3‐hydroxybutyrate) or P3HB.

Evaluation of biodecolorization of the textile azo dye by halophilic archaea [PDF]
Introduction: Azo dyes are the biggest group of colors. One of the special characteristic of this group of dye is the presence of double bonds of Nitrogen (N=N). Several studies reported biodecolorization using microorganisms, so far.

The composition of C50 carotenoid bacterioruberin and its derivatives were identified in halophilic archaea Haloferax marinum MBLA0078, which exhibit potent antioxidant properties and protect against lipopolysaccharide‐induced C2C12 myotube atrophy, possibly through Akt/mTOR pathway activation, indicating their potential as natural antioxidants and ...

New insights into Chlorella vulgaris applications
Abstract Environmental pollution is a big challenge that has been faced by humans in contemporary life. In this context, fossil fuel, cement production, and plastic waste pose a direct threat to the environment and biodiversity. One of the prominent solutions is the use of renewable sources, and different organisms to valorize wastes into green energy ...

Interplay of intracellular and trans‐cellular DNA methylation in natural archaeal consortia
This study examined genome methylation in Haloferax lucertense and its DPANN symbiont, Candidatus Nanohalococcus occultus, within an archaeal halophilic xylan‐degrading community. It revealed a complex methylation pattern in the genome of H. lucertense and presented the first evidence of cross‐methylation by the symbiont's methyltransferases ...
