New Horizons for Deep Subsurface Microbiology

Microbe Magazine, 2009
The U.S. Department of Energy (DOE) launched the modern era of subsurface microbiology at its Savannah River Plant (SRP) in South Carolina in 1986. Those first efforts, involving three 200-m-deep wells along with procedures to monitor for drilling-related contaminants, uncovered abundant and diverse microbial communities in subsurface aquifers (Fig. 1).

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

Subsurface Petroleum Microbiology

2013
The importance of microbial activities in petroleum oilfields and reservoirs has been recognized for a long time, but our knowledge of the diversity of bacteria growing in these ecosystems and their metabolic activities in situ is still limited. Petroleum biotransformations in near surface or subsurface environments are achieved by either aerobic or ...

Artificial subsurface lithoautotrophic microbial ecosystems and gas storage in deep subsurface

FEMS Microbiology Ecology
Over the next few years, it is planned to convert all or part of the underground gas storage (UGS) facilities used for natural gas (salt caverns, depleted hydrocarbon reservoirs, and deep aquifers) into underground dihydrogen (H2) storage reservoirs ...

Microbiological characterization and nitrate reduction in subsurface soils

Biology and Fertility of Soils, 1989
Two borings (20 m depth) were performed in a sandy-clayey soil over a limestone bed and in a sandy soil with lumps of clay in some depths. Bacteria were found in the deeper soil layers of both profiles. The methods used to detect bacteria were those normally used for topsoil layers, plate counts of bacteria, ATP content, and direct microscopy ...

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 ...
