Uncovering the chemical and physical links between natural environments and microbial communities is becoming increasingly amenable owing to geochemical observations and metagenomic sequencing. At the hot spring known as Bison Pool in Yellowstone National Park, the cooling of the water in the outflow channel is associated with an increase in oxidation potential estimated from multiple field-bas...

Branched glycerol dialkyl glycerol tetraethers (bGDGTs) are predominantly found in soils and peat bogs. In this study, we analyzed core (C)-bGDGTs after hydrolysis of polar fractions using liquid chromatography-atmospheric pressure chemical ionization-mass spectrometry and analyzed intact P-bGDGTs using total lipid extract (TLE) without hydrolysis by liquid chromatography-electrospray ionizatio...

Nucleotide and amino acid compositions were studied to determine the genomic and structural relationship of photolyase gene in freshwater, marine and hot spring cyanobacteria. Among three habitats, photolyase encoding genes from hot spring cyanobacteria were found to have highest GC content. The genomic GC content was found to influence the codon usage and amino acid variability in photolyases....

We report the consensus genome sequence of a novel GC-rich rudivirus, designated SMR1 (Sulfolobales Mexican rudivirus 1), assembled from a high-throughput sequenced environmental sample from a hot spring in Los Azufres National Park in western Mexico.

Thermoanaerobaculum aquaticum MP-01(T) is currently the only cultivated and described member of Acidobacteria subdivision 23. Here, we report the genome sequence for this novel microorganism that was isolated from a hot spring.

Thermus sp. isolate 2.9 was obtained from a hot water spring in Salta, Argentina. Here, we report the draft genome sequence (2,485,434 bp) of this isolate, which consists of 11 scaffolds of >10 kbp and 2,719 protein-coding sequences.

Tepidiphilus thermophilus strain JHK30(T) was isolated from a hot spring at Surajkund, Jharkhand, India. It is a Gram-negative rod, nonsporulating, aerobic, and motile. The estimated genome is 2.3 Mb, with 2,186 protein-coding sequences.

Geobacillus stearothermophilus strains 22 and 53 were isolated from sediment samples isolated from the Garga hot spring (72°C) located in the valley of the river Barguzin (the Baikal region, Russian Federation) (54°19'3.72″N, 110°59'38.4″E).
