Expanding frontiers in deep subsurface microbiology

Palaeogeography, Palaeoclimatology, Palaeoecology, 2005
Abstract The subsurface biosphere on Earth appears to be far more expansive and physiologically and phylogenetically complex than previously thought. Here, several aspects of subsurface microbiology are discussed. Molecular and biogeochemical data, as well as characteristics from new isolates, suggest that ecosystems below deep-sea hydrothermal vents

Utility of radiotracer activity measurements for subsurface microbiology studies

Journal of Microbiological Methods, 1989
Radiotracer activity measurements were conducted on subsurface sediments collected from the Savannah River Plant, Aiken, SC. Sediments were aseptically extruded from stainless steel core liners into a nitrogen flushed glove bag. Subsurface materials were immediately inoculated into aerobic and/or anaerobic tubes for time course experiments ...

Effect of Chemical Oxidation on Subsurface Microbiology and Trichloroethene (TCE) Biodegradation

Bioremediation Journal, 2000
Abstract Research was conducted to determine the effect of chemical oxidation on subsurface microbiology and cometabolic biodegradation capacity in a trichloroethene (TCE)/perchloroethene (PCE)-contaminated aquifer previously treated with Fenton's reagent. Groundwater pH declined from 5 to 2.4 immediately after the treatment, and subsequently rose to a

Microbiology of the Deep Subsurface Geosphere and Its Implications for Used Nuclear Fuel Repositories

Advances in Environmental Microbiology, 2016
A number of countries are actively working toward the siting and development of deep geological repositories (DGR) for used nuclear fuel. Given their ubiquity and metabolic capabilities, it is assumed that with sufficient time and appropriate conditions, microorganisms could alter the geochemistry of the repository. As such, the DGR concept provides an
