The structure provides molecular insight into how reduction of insoluble substrates (e.g., minerals), soluble substrates (e.g., flavins), and cytochrome redox partners might be possible in tandem at different termini of a trifurcated electron-transport chain on the cell surface.

Zoomed-in view of a 3D visualization of pore-scale fluid flow computed using the parallel Smoothed Particle Hydrodynamics code developed under this project. Solid grains are represented as shaded gray quasi-spheres. Transparent surfaces indicate regions of high fluid flow velocity. Traces of individual fluid particles are also shown, colored according to their velocity (with bright green being the fastest particles). Visualization created by Kwan-Liu Ma and colleagues at the Institute for Ultra-Scale Visualization, University of California at Davis.
Genome-based techniques are helping to advance a predictive understanding of the function and activity of microbial communities in the environment.
