Anaerobic hydrocarbon biodegradation in deep subsurface oil reservoirs
Nature, 2004Biodegradation of crude oil in subsurface petroleum reservoirs is an important alteration process with major economic consequences. Aerobic degradation of petroleum hydrocarbons at the surface is well documented and it has long been thought that the flow of oxygen- and nutrient-bearing meteoric waters into reservoirs was necessary for in-reservoir ...

Expanding frontiers in deep subsurface microbiology
Palaeogeography, Palaeoclimatology, Palaeoecology, 2005Abstract 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

Denitrification in deep subsurface sediments
Geomicrobiology Journal, 1989Abstract Dissimilatory nitrate reduction (denitrification) in subsurface sediments by indigenous microflora was investigated in samples obtained over a range of depths from 0 to 289 m. Denitrifying activity in sediment samples retrieved from similar stratigraphic horizons at four different sites was determined by measuring the accumulation of N2O using

Fungi in Deep Subsurface Environments
2018The igneous crust of the oceans and the continents represents the major part of Earth's lithosphere and has recently been recognized as a substantial, yet underexplored, microbial habitat. While prokaryotes have been the focus of most investigations, microeukaryotes have been surprisingly neglected.

Integrated Geomechanical Modelling for Deep Subsurface Damage
63rd EAGE Conference & Exhibition, 2001Government, E&P and mining industry increasingly demand fundamental insight and accurate predictions on subsurface and surface deformation and damage due to exploitation of subsurface natural resources, and subsurface storage of energy residues (e.g. CO2).

Characterizing the Deep Terrestrial Subsurface Microbiome
2018A large portion of the earth's biomass resides in the subsurface and recent studies have expanded our knowledge of indigenous microbial life. Advances in the field of metagenomics now allow analysis of microbial communities from low-biomass samples such as deep (>2.5 km) shale core samples.

New Horizons for Deep Subsurface Microbiology
Microbe Magazine, 2009The 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).

Microbial Life in Deep Terrestrial Subsurfaces
BioScience, 1989In 1985 the US Department of Energy (DOE) established a research program called Microbiology of the Deep Subsurface, which focuses on detecting microorganisms at greater depths, establishing fundamental scientific information, including their ecology, and exploring their potential use in clean-up of contaminated deep terrestrial sediments and ...

Deep Biosphere: Microbiome of the Deep Terrestrial Subsurface
2019Deep biosphere represents an unexplored realm of planetary life residing underneath the continental and oceanic crusts that constitutes majorly of prokaryotic life forms bacteria and archaea. Microbial communities which reside within various deep subsurface environments form a significant but largely unknown portion of the Earth’s biosphere.

Geomicrobiology and Metagenomics of Terrestrial Deep Subsurface Microbiomes
2016Fractures in the deep subsurface of Earth's crust are inhabited by diverse microbial communities that participate in biogeochemical cycles of the Earth. Life on Earth, which arose c. 3.5-4.0 billion years ago, reaches down at least 5 km in the crust. Deep mines, caves, and boreholes have provided scientists with opportunities to sample deep subsurface ...
