Geomicrobiology of sublacustrine thermal vents in Yellowstone Lake: geochemical controls on microbial community structure and function
Yellowstone Lake (Yellowstone National Park, WY, USA) is a large high-altitude (2200 m), fresh-water lake, which straddles an extensive caldera and is the center of significant geothermal activity. The primary goal of this interdisciplinary study was to evaluate the microbial populations inhabiting thermal vent communities in Yellowstone Lake using 16S rRNA gene and random metagenome sequencing...
متن کاملMetals, minerals and microbes: geomicrobiology and bioremediation.
Microbes play key geoactive roles in the biosphere, particularly in the areas of element biotransformations and biogeochemical cycling, metal and mineral transformations, decomposition, bioweathering, and soil and sediment formation. All kinds of microbes, including prokaryotes and eukaryotes and their symbiotic associations with each other and 'higher organisms', can contribute actively to geo...
متن کاملLearning geomicrobiology as a team using microbial mats, a multidisciplinary approach.
Microbial mats are one of the best suited laminar organo-sedimentary ecosystems for students from different educational backgrounds to visualize the direct relationship between microbes and minerals. We have used tropical hypersaline microbial mats from Puerto Rico as educational tools to promote active learning of geomicrobiology introductory concepts for undergraduate students organized in mu...
متن کاملGeomicrobiology of manganese(II) oxidation.
Mn(II)-oxidizing microbes have an integral role in the biogeochemical cycling of manganese, iron, nitrogen, carbon, sulfur, and several nutrients and trace metals. There is great interest in mechanistically understanding these cycles and defining the importance of Mn(II)-oxidizing bacteria in modern and ancient geochemical environments. Linking Mn(II) oxidation to cellular function, although st...
متن کاملChanges in microbial community composition and geochemistry during uranium and technetium bioimmobilization.
In a previous column study, we investigated the long-term impact of ethanol additions on U and Tc mobility in groundwater (M. M. Michalsen et al., Environ. Sci. Technol. 40:7048-7053, 2006). Ethanol additions stimulated iron- and sulfate-reducing conditions and significantly enhanced U and Tc removal from groundwater compared to an identical column that received no ethanol additions (control). ...
