Anaerobic reduction of hexavalent chromium by subsurface microorganisms.
(1999)
Anaerobic sediments from an aquifer contaminated with landfill leachate were used to study the potential for microbial reduction of Cr(VI) to Cr(III). The lightly colored, sandy sediments slowly reduced Cr(VI) in viable, ...
The ecology and biogeochemistry of sulfate reduction in the terrestrial subsurface.
(1999)
I believe that the ubiquity and importance of sulfate reduction in subsurface environments is a reflection of the diversity of the hydrological and biogeochemical processes which contribute to the availability of sulfate. ...
Responses of Terrestrial Biogeochemical Cycles to Global Change – Syntheses and Data-Model Integration
(2016-12)
Global observations and model simulations show that atmospheric carbon dioxide (CO2) concentrations and surface temperatures have been and will keep increasing. These environmental changes have significant influences on ...
Magnetic minerals: Understanding the processes of formation in soils and clays and identifying their presence in the rock record.
(2001)
This work presents results of biological formation of magnetite under a variety of laboratory conditions in a hydrocarbon-contaminated soil profile. Magnetite was formed only in biological samples but not in the abiotic: ...
