Última Exploration des communautés virales thermophiles dans les écosystèmes chauds des Terres australes et antarctiques françaises ArchiMer Parikka, Kaarle Joonas. Viruses thrive in all types of ecosystems where life is found. They represent the most abundant biological entity of our biosphere. Though several studies have been conducted on viral abundance and dynamics in mesophilic aquatic ecosystems, these aspects remain largely unexplored in extremophilic environments, such as hot springs. In this study, prokaryotic and associated viral communities of the French Southern and Antarctic Lands hot springs were explored. First, prokaryotic cells and Virus-like particles (VLP) were enumerated in several terrestrial and inshore hot springs. The results reveal an abundance of 105 - 106 particles/ml in both types of hot springs studied. The virus-to-prokaryote ratios (VPR) were generally low, confirming thus actual...

MVS3 isolated from Indian hot spring BABT Acharya,Somen; Chaudhary,Anita. The aim of this work was to study the effect of some nutritional and environmental factors on the production of cellulases, in particular endoglucanase (CMCase) and exoglucanases (FPase) from Bacillus licheniformis MVS1 and Bacillus sp. MVS3 isolated from an Indian hot spring. The characterization study indicated that the optimum pH and temperature value was 6.5 to 7.0 and 50-55°C, respectively. Maximum cellulases production by both the isolates was detected after 60 h incubation period using wheat and rice straw. The combination of inorganic and organic nitrogen source was suitable for cellulases production. Overall, FPase production was much higher than CMCase production by both of the strains. Between the two thermophiles, the cellulolytic activity was...
