Mössbauer Analysis of Microbial Redox Transformations of Naturally Occurring Fe(III)-bearing Phyllosilicates

Lead Institution

University of Wisconsin, Madison

Principal Investigator

Evgenya Shelobolina

Project type

Large-Scale EMSL Research

The abundance of ferric iron in sedimentary environments and its ability to accept and donate electrons makes it important electron acceptor for microbial metabolism. Fe(III) in the structure of…

Mossbauer Analysis of Microbial Redox Transformations of Fe-bearing Phyllosilicate and Oxide Minerals

Lead Institution

University of Wisconsin, Madison

Principal Investigator

Eric Roden

Project type

Large-Scale EMSL Research

Microbial Fe redox transformations have a major impact on the aqueous and solid-phase geochemistry of subsurface environments, as well as on the behavior of various organic and inorganic contaminants…

Spectroscopic Confirmation of Enzymatic Oxidation of Structural Fe(II) in Biotite by a Lithoautotrophic Fe(II)-oxidizing Bacterial Culture

Lead Institution

University of Wisconsin, Madison

Principal Investigator

Eric Roden

Project type

Limited Scope

The key rationale for submission of this rapid access user proposal is that we are nearing closure on the novel discovery of the potential for enzymatic oxidation of Fe(II) in biotite (see below),…
