Structure and application of antifreeze proteins from Antarctic bacteria
TLDR
Modeled proteins possess a β-helix structure, and molecular docking analysis revealed the AFP gu3B could be the most efficient AFPs in order to avoid the formation of ice crystals, even when gu3A has a higher affinity for ice.
Biotransformation of 2,4,6-Trinitrotoluene by Pseudomonas sp. TNT3 isolated from Deception Island, Antarctica.
TLDR
The screening and isolation of TNT-degrading bacteria from Antarctic environmental samples with potential use as bioremediation agents is reported for the first time, showing that TNT biotransformation involves the reduction of the nitro groups.
Isolation and partial characterization of a new moderate thermophilic Albidovulum sp. SLM16 with transaminase activity from Deception Island, Antarctica
TLDR
Strain SLM16 is a moderate thermophilic Gram negative microorganisms which belongs to the marine bacterial genus Al bidovulum and is closely related to Albidovulum inexpectatum species based on phylogenetic analysis.
Characterization of a novel thermostable (S)-amine-transaminase from an Antarctic moderately-thermophilic bacterium Albidovulum sp. SLM16.
TLDR
Results indicate that ATA_SLM16 is an excellent candidate for potential applications in biocatalytic synthesis, and the first report of the characterization of a thermostable (S)-ATA discovered by means of in vivo screening of thermophilic microorganisms.
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
TLDR
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.
Living to the high extreme: unraveling the composition, structure, and functional insights of bacterial communities thriving in the arsenic-rich Salar de Huasco – Altiplanic ecosystem
TLDR
It is concluded that Salar de Huasco microbial communities are diverse and possess a broad genetic repertoire to thrive under extreme conditions, including increasing concentrations of the highly toxic As.
Sequences of Endophytic Fungal and Bacterial Communities from Araucaria araucana [(Molina) K. Koch, 1869] in the Coastal and Andes Mountain Ranges, Chile
Here, we report the results from PCR and sequencing of bacterial 16S rRNA and fungal internal transcribed spacer 1 (ITS1) genes from needle, branch, trunk, and root samples of Araucaria araucana,…
Genomic and metagenomic exploration of microbial endophytes and a new potential Phytophthora species in the monkey puzzle tree Araucaria araucana in Chile
TLDR
Community analyses suggest that Araucaria’s microbial communities are structured primarily within tree by tissue, and secondarily by sampling site, i.e., Andes or Nahuelbuta mountain ranges and north/south gradient.
Living to the High Extreme: Unraveling the Composition, Structure, and Functional Insights of Bacterial Communities Thriving in the Arsenic-Rich Salar de Huasco Altiplanic Ecosystem
TLDR
Highly specialized communities thriving in little-explored environments subjected to several pressures that have the potential for unraveling technologies to face the repercussions of climate change in many areas of interest are described.
Composition and structure of the skin microbiota of rorquals off the Eastern South Pacific.
TLDR
This is the first report on the composition and structure of the skin microbiota of whales off the coast of Chile, providing a foundational dataset to understand the microbiota's role in rorquals.
