Metagenomic study of red biofilms from Diamante Lake reveals ancient arsenic bioenergetics in haloarchaea
(Nature Publishing Group, 2015-07)
Arsenic metabolism is proposed to be an ancient mechanism in microbial life. Different bacteria and archaea use detoxification processes to grow under high arsenic concentration. Some of them are also able to use arsenic ...
Haloarchaea from the Andean Puna: Biological Role in the Energy Metabolism of Arsenic
(Springer, 2018-10)
Biofilms, microbial mats, and microbialites dwell under highly limiting conditions (high salinity, extreme aridity, pH, and elevated arsenic concentration) in the Andean Puna. Only recent pioneering studies have described ...
Analysis of carotenoids in haloarchaea species from Atacama saline lakes by high resolution UHPLC-Q-Orbitrap-Mass Spectrometry: antioxidant potential and biological effect on cell viability
(MDPI, 2021)
Haloarchaea are extreme halophilic microorganisms belonging to the domain Archaea, phylum Euryarchaeota, and are producers of interesting antioxidant carotenoid compounds. In this study, four new strains of Haloarcula sp., ...
Proteomic study of the exponential-stationary growth phase transition in the haloarchaea Natrialba magadii and Haloferax volcanii
(Wiley VCH Verlag, 2018-07)
The dynamic changes that take place along the phases of microbial growth (lag, exponential, stationary, and death) have been widely studied in bacteria at the molecular and cellular levels, but little is known for archaea. ...
Biodegradation of aromatic hydrocarbons by Haloarchaea and their use for the reduction of the chemical oxygen demand of hypersaline petroleum produced water

(2021)
Haloarchaea are extreme halophilic microorganisms belonging to the domain Archaea, phylum Euryarchaeota, and are producers of interesting antioxidant carotenoid compounds. In this study, four new strains of Haloarcula sp., ...
A Unique Natural Laboratory to Study Polyextremophile Microorganisms: Diamante Lake as a Window to the Origin of Life
(Springer Nature Switzerland AG, 2020)
Diamante Lake is located at 4589 m above sea level (m a.s.l.) inside the Galán Volcano caldera and presents extreme environmental conditions, such as high arsenic concentration (210 mg l−1), salinity, pH and UV radiation. ...
Bacteriorodhopsin or arsenite as energy source in the growth of haloarchaea
(Grupo Argentino de Fotobiología, 2016)
The Lon protease from the haloalkaliphilic archaeon Natrialba magadii is transcriptionally linked to a cluster of putative membrane proteases and displays DNA-binding activity
(Elsevier Gmbh, 2011-05)
The ATP-dependent Lon protease is universally distributed in bacteria, eukaryotic organelles and archaea. In comparison with bacterial and eukaryal Lon proteases, the biology of the archaeal Lon has been studied to a limited ...
