In this work, two deep subsurface wastewater infiltration systems (SWISs) were constructed and fed with domestic sewage (control system, S1) and mixed wastewater consisting of old landfill leachate and domestic sewage (experimental system, S2). S1 and S2

Deep subsurface biofilms are estimated to host the majority of prokaryotic life on Earth, yet fundamental aspects of their ecology remain unknown. An inherent difficulty in studying subsurface biofilms is that of sample acquisition.

Deep subsurface microbial processes
Reviews of Geophysics, 1995Information on the microbiology of the deep subsurface is necessary in order to understand the factors controlling the rate and extent of the microbially catalyzed redox reactions that influence the geophysical properties of these environments. Furthermore, there is an increasing threat that deep aquifers, an important drinking water resource, may be ...

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 ...
