Stable microbial community in compacted bentonite after 5 years of exposure to natural granitic groundwater

mSphere, 2023
The Materials Corrosion Test (MaCoTe) at the Underground Research Laboratory in Grimsel, Switzerland, assesses the microbiology and corrosion behavior of engineered barrier components of a deep geological repository (DGR) for long-term disposal of high ...

Biogeography and evolution of Thermococcus isolates from hydrothermal vent systems of the Pacific

Frontiers in Microbiology, 2015
Thermococcus is a genus of hyperthermophilic archaea that is ubiquitous in marine hydrothermal environments growing in anaerobic subsurface habitats but able to survive in cold oxygenated seawater.

Bacterial Diversity and Composition in Oylat Cave (Turkey) with Combined Sanger/Pyrosequencing Approach [PDF]

Polish Journal of Microbiology, 2016
The microbiology of caves is an important topic for better understanding subsurface biosphere diversity. The diversity and taxonomic composition of bacterial communities associated with cave walls of the Oylat Cave was studied first time by molecular ...

Microbial Communities in a Serpentinizing Aquifer Are Assembled through Strong Concurrent Dispersal Limitation and Selection

mSystems, 2021
In recent years, our appreciation of the extent of habitable environments in Earth’s subsurface has greatly expanded, as has our understanding of the biodiversity contained within.

Local and Regional Diversity Reveals Dispersal Limitation and Drift as Drivers for Groundwater Bacterial Communities from a Fractured Granite Formation

Frontiers in Microbiology, 2016
Microorganisms found in terrestrial subsurface environments make up a large proportion of the Earth’s biomass. Biogeochemical cycles catalysed by subsurface microbes have the potential to influence the speciation and transport of radionuclides managed ...

Microbiological Comparisons within and across Contiguous Lacustrine, Paleosol, and Fluvial Subsurface Sediments [PDF]

Applied and Environmental Microbiology, 1995
Twenty-six subsurface samples were collected from a borehole at depths of 173.3 to 196.8 m in the saturated zone at the Hanford Site in south-central Washington State. The sampling was performed throughout strata that included fine-grained lacustrine (lake) sediments, a paleosol (buried soil) sequence, and coarse-grained fluvial (river) sediments.

Microbial Community Structure of Subglacial Lake Whillans, West Antarctica

Frontiers in Microbiology, 2016
Subglacial Lake Whillans (SLW), located beneath ~800 m of ice on the Whillans Ice Stream in West Antarctica was sampled in January of 2013, providing the first opportunity to directly examine water and sediments from an Antarctic subglacial lake.

Microbiological Quality of Subsurface Drainage Water from Irrigated Agricultural Land [PDF]

Journal of Environmental Quality, 1972
AbstractIrrigation and subsurface drainage waters sampled from an 82,150‐hectare (203,000‐acre) irrigation district in southern Idaho were evaluated for bacteriological quality. The soils in the district are wind deposited over fractured basalt, calcareous, and have a pH near 7.8.

Identification and Removal of Contaminant Sequences From Ribosomal Gene Databases: Lessons From the Census of Deep Life

Frontiers in Microbiology, 2018
Earth’s subsurface environment is one of the largest, yet least studied, biomes on Earth, and many questions remain regarding what microorganisms are indigenous to the subsurface. Through the activity of the Census of Deep Life (CoDL) and the Deep Carbon

Enrichment and Genomic Characterization of a N2O-Reducing Chemolithoautotroph From a Deep-Sea Hydrothermal Vent

Frontiers in Bioengineering and Biotechnology, 2018
Nitrous oxide (N2O) is a greenhouse gas and also leads to stratospheric ozone depletion. In natural environments, only a single N2O sink process is the microbial reduction of N2O to N2, which is mediated by nitrous oxide reductase (NosZ) encoded by nosZ ...
