Session – Microbe Mediated Electron Transfer in Mineral-fluid Systems and Environmental Consequences

This session will examine the environmental consequence of microbe-mineral interaction in critical zone. Microorganisms have been proven to be capable to mediate the redox dynamics of minerals, which commonly alters the chemical states of most of major and trace elements of environmental concern. An important issue is the mechanism of microbial electron transfer with minerals as electron sources and sinks. The purpose of this session is to combine cross-disciplinary synergies experts in mineralogy, microbiology, and biogeochemistry. All the contributions focusing on outer-membrane proteins, microbial extracellular electron transfer, electron shuttle, biofilm development and evolution, and mineral surface alteration are all invited.

The key scientific questions are: (1) what are the molecular mechanisms for long-distance, short-distance or direct electron transfer to mineral surfaces and other microbial cells? (2) How do the physic-chemical properties of minerals control the kinetics of electron transfer? (3) How do the solar light, photoelectrons emitted from semiconducting minerals, and species in solution influence the microbe-mineral interaction? (4) How does the microbe-mineral interaction impact the redox processes of contaminant (semi-) metals as well as the environmental consequences at various spatial and temporal scales? We cordially encourage field-based, lab-based experimental, and theoretical contributions, including advances in ‘omics studies and analytical techniques.
