Concentrations of bacteria, fungi, ammonium, nitrate, nitrite, orthophosphate, sulfate, and certain metals were enriched in freshwater-surface microlayer samples relative to the bulk-subsurface water. Results differed markedly depending on which of three methods for surface-microlayer collection was used. This report suggests that the biologically and

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.

Geochimica et Cosmochimica Acta, 2006
A detailed geochemical and microbiological study of a ~2 m sediment core from the inactive Alvin mounds within the TAG hydrothermal field was conducted to examine, for the first time, the role of prokaryotes in subsurface weathering of hydrothermal sediments. Results show that there has been substantial post depositional remobilisation of metal species

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 (

The Influence of Microbiological Processes on Subsurface Waters and Grounds in River Dam Basement
2014Microbes are ubiquitous on the Earth and take an active part in the transformation of the geological environment. Their activity can change the geochemical parameters of ground and groundwater and lead to undesirable consequences after the building of hydrotechnical facilities, especially pressure ones.
