Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …

Sulphate-reducing microorganisms (SRMs) are a phylogenetically diverse group of
anaerobes encompassing distinct physiologies with a broad ecological distribution. As …

Soil pollution occurring at mining sites has adverse impacts on soil microbial diversity. New
approaches, such as metagenomics approach, have become a powerful tool to investigate …

The effect of long-term mixed-waste contamination, particularly uranium and nitrate, on the
microbial community in the terrestrial subsurface was investigated at the field scale at the …

A central tenant in microbial biogeochemistry is that microbial metabolisms follow a
predictable sequence of terminal electron acceptors based on the energetic yield for the …

Two continuous‐flow bench‐scale bioreactor systems populated by mixed communities of
acidophilic sulfate‐reducing bacteria were constructed and tested for their abilities to …

H 2-driven reduction of hexavalent chromium (Cr (VI)) using precious-metal catalysts is
promising, but its implementation in water treatment has been restricted by poor H 2-transfer …

Iron (Fe) oxides exist in a spectrum of structures in the environment, with ferrihydrite widely
considered the most bioavailable phase. Yet, ferrihydrite is unstable and rapidly transforms …

Adsorption and subsequent reduction of U (VI) on Fe (II)-bearing clay minerals can control
the mobility of uranium in subsurface environments. Clays such as montmorillonite provide …

In terrestrial subsurface environments where nitrate is a critical groundwater contaminant,
few cultivated representatives are available to verify the metabolism of organisms that …
