The focus of this project is to characterize microbial communities as they form biofilms in porous media using x-ray Computed Microtomography (CMT). The actual architecture of biofilms in the subsurface is a bit of an open question, particularly how this architecture evolves in response to changes in hydrodynamics and other growth limiting or enhancing conditions. Similarly, the influence of the evolving biomass on the hydrodynamics is an important factor when designing and managing bioremediation at a field site.
