The structure provides molecular insight into how reduction of insoluble substrates (e.g., minerals), oluble 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).
