Study of Electron Transfer between Bacteria and Mineral


EMSL Project ID
50017

Abstract

The aim of this study is to determine the structural arrangement of proteins and conformational changes on a mineral surface under physiologically relevant conditions. This is important for a detailed understanding of the respiration of anaerobic microorganisms which transfer electrons to redox-active minerals as part of this process. The structure will be determined using neutron reflectivity at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory, and requires a large flat surface. The purpose of this proposal is to prepare films of hematite (?-Fe2O3) on flat substrates using EMSL’s microfabrication and deposition facilities.
