Extreme ecosystems such as hot springs are of great interest as a source of novel extremophilic species, enzymes, metabolic functions for survival and biotechnological products. India harbors hundreds of hot springs, the majority of which are not yet explored and require comprehensive studies to unravel their unknown and untapped phylogenetic and functional diversity. The aim of this study was ...

[1] Numerous hot springs flow within the steeply incised gorges of the central Nepal Himalayan front. The spring fluids have total dissolved solids (TDS) up to 7000 mg/L and Na, and K typically comprise >50% of the cationic charge, indicating that high-temperature silicate alteration is the dominant source of hot spring alkalinity. HCO3 is normally the dominant anion. Sr isotope ratios from the...

The current view of virus diversity in terrestrial hot springs is limited to a few sampling sites. To expand our current understanding of hot spring viral community diversity, this study aimed to investigate the first African hot spring (Brandvlei hot spring; 60 °C, pH 5.7) by means of electron microscopy and sequencing of the virus fraction. Microscopy analysis revealed a mixture of regular- a...

Insights about the distribution of the microbial community prove to be the major goal of understanding microbial ecology which remains to be fully deciphered. Hot springs being hub for the thermophilic microbiota attract the attention of the microbiologists. Deulajhari hot spring cluster is located in the Angul district of Odisha. Covered within a wooded area, Deulajhari hot spring is also fed ...

Temperature variability impact on physiological, hematological and biochemical parameters of growing and adult Karan Fries cattle was studied during hot humid, winter, spring and summer. During forenoon and afternoon the respiration rate (RR) and rectal temperature (RT) increased by 4.67 and 3.67 breaths/min and 0.87°C and 0.77°C respectively in growing KF cows during summer over spring. The re...

The Anoxybacillus flavithermus KU2-6-11 was isolated from sediments of a nameless hot spring. The hot spring is located in Uzon caldera (Kamchatka, Russia). The sequenced and annotated genome is 2,646,305 bp and encodes 2787genes. The draft genome sequence of the Anoxybacillus flavithermus KU2-6-11 has been deposited at DDBJ/EMBL/GenBank under the accession PEDM01000000 and the sequences could ...

The Thermoactinomyces sp. strain Gus2-1 was isolated from hot-spring sediments sample from the hot-spring Gusikha in Bargusin Valley (Baikal Rift Zone, Russia). The sequenced and annotated genome is 2,623,309 bp and encodes 2513 genes. The draft genome sequence of the Thermoactinomyces sp. strain Gus2-1 has been deposited at DDBJ/EMBL/GenBank under the accession JPZM01000000 and the sequences c...

A thermophilic, endospore-forming, and radiation resistant bacterium, strain TS3-9, was isolated from the radon hot spring. Based on phenotype, fatty acid, G + C mol %, and phylogenetic analysis, TS3-9 was assigned to the genus Geobacillus. In addition to surviving exposure to gamol/La irradiation (D10 = 10 kGy), TS3-9 produced an exopolysaccharide (EPS), the average molecular weight was approx...
