Characterization of the microbiology within a 21 m3section of rock from the deep subsurface
Microbial Ecology, 1993The distribution of aerobic chemoheterotrophic microorganisms within a 21 m3 section of deep subsurface rock was determined. Nineteen samples for microbiological analysis were aseptically taken by hand from the walls of a 400 m deep subsurface tunnel after an alpine miner created fresh rock faces 0.76, 1.52, 2.28, and 3.04 m into the tunnel wall.

This chapter gives the reader an introduction into the microbiology of deep geological systems with a special focus on potential geobiotechnological applications and respective risk assessments. It has been known for decades that microbial activity is responsible for the degradation or conversion of hydrocarbons in oil, gas, and coal reservoirs.

Microbiological Transformations of Low-Molecular-Weight Carbon Compounds in the Deep Subsurface
1993Methanogenesis, sulfate reduction, and acetogenesis were studied in the deep subsurface waters of two exploited oil fields. Higher rates of methanogenesis (mean value of 2.16 µg CH4 L-1 d-1) were found in the faintly mineralized waters of the Mychpayskoe oil field, which contained low sulfate concentrations. In the waters of the Bondyuzhskoe oil field (

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
