Microbial communities inhabiting extreme environments like Salar de Huasco (SH) are adapted to thrive while exposed to several abiotic pressures and the presence of toxic elements like arsenic (As). Hence, we aimed to uncover the role of arsenic in shaping bacterial composition, structure, and functional potential in five different sites in this Altiplanic wetland using a shotgun metagenomic approach. The sites exhibit wide gradients of arsenic (9 to 321 mg/kg), and our results showed highly…

Comparative Genomics and Physiological Investigation of a New Arthrospira/Limnospira Strain O9.13F Isolated from an Alkaline, Winter Freezing, Siberian Lake.
The comprehensive genome-based characterisation and physiological investigation of the new strain O9.13F that was isolated in a temperate climate zone from the winter freezing Solenoye Lake in Western Siberia showed no unique genes had been found for the Siberian strain related to its tolerance to low temperatures and does not possess a different set of genes associated with the salinity stress response from those typically found in tropical strains.
Diversity of Lysis-Resistant Bacteria and Archaea in the Polyextreme Environment of Salar de Huasco
The results show a high diversity of lysis-resistant cells not only in bacteria but also in archaea, hinting at a generalized resistance to lysis, which is at least comparable to the resistance of dormant cells in bacteria.


Genomic Variation and Arsenic Tolerance Emerged as Niche Specific Adaptations by Different Exiguobacterium Strains Isolated From the Extreme Salar de Huasco Environment in Chilean – Altiplano
Exiguobacterium strains from SH are adapted to physiologically overcome the contrasting environmental conditions, like the arsenic present in their habitat, and Interestingly, these observations correlate with physiological traits such as growth patterns, gene expression, and enzyme activity related to arsenic response and/or tolerance.
Phosphate-Arsenic Interactions in Halophilic Microorganisms of the Microbial Mat from Laguna Tebenquiche: from the Microenvironment to the Genomes
The biological role of As and the effect of phosphate in AMEs from the Laguna Tebenquiche (Atacama Desert, Chile) is characterized and As is revealed as a key component of the microbial mat ecosystem.
Arsenic metabolism in high altitude modern stromatolites revealed by metagenomic analysis
An in-depth analysis revealed a surprisingly diverse metabolism comprising all known types of As resistance and energy generating pathways, while the ars operon was the main mechanism and an important abundance of arsM genes was observed in selected phyla.
Microbial Community Structure and the Persistence of Cyanobacterial Populations in Salt Crusts of the Hyperarid Atacama Desert from Genome-Resolved Metagenomics
It is concluded that moisture level, controlled by coastal fog intensity, is the strongest driver of community membership.
Characterization and Salt Response in Recurrent Halotolerant Exiguobacterium sp. SH31 Isolated From Sediments of Salar de Huasco, Chilean Altiplano
Poly-extremophiles microorganisms have the capacity to inhabit hostile environments and can survive several adverse conditions that include as variations in temperature, pH, and salinity, high levels
Large Differences in Bacterial Community Composition among Three Nearby Extreme Waterbodies of the High Andean Plateau
It is highlighted that Altiplano peatland ponds represent a hitherto unknown source of microbial diversity, and even at the very small-scale spatial range considered, local environmental factors are important in explaining differences in bacterial community composition in those systems.
Arsenic Response of Three Altiplanic Exiguobacterium Strains With Different Tolerance Levels Against the Metalloid Species: A Proteomics Study
Light is shed into the physiology necessary for Exiguobacterium bacteria to be able to tolerate the toxicity and stress generated by the presence of arsenic in their niche.
Comparative Genomics Analysis of a New Exiguobacterium Strain from Salar de Huasco Reveals a Repertoire of Stress-Related Genes and Arsenic Resistance
Strain SH31 was able to grow in up to 10 mM arsenite and 100 mM arsenate, indicating that it is arsenic resistant, and expression of the ars operon and acr3 was strongly induced in response to both toxics, suggesting that the arsenic efflux pump Acr3 mediates arsenic resistance in Exiguobacterium sp.
Novelty and spatio–temporal heterogeneity in the bacterial diversity of hypersaline Lake Tebenquiche (Salar de Atacama)
The bacterioplankton structure of this lake was analyzed by 16S rRNA gene analyses along a spatio–temporal survey and included several novel microorganisms of environmental importance and appeared as a large unexplored reservoir of unknown bacteria.
