In subsurface environments, a large number of biogeochemical reactions have a kinetics controlled mainly by bacteria. In these environments, nutrient fluxes and solute concentrations can be highly variable over space and time. These variations can generate bio-geochemical reaction kinetics that differ significantly from the cases measured in homogeneous environmental models. The general objective of this work is, using microfluidic experiments and based only on physical descriptors, to quantify the couplings between flow heterogeneity, solute transport/mixing, reactions and biological activity. Our experiments are coupled with numerical modeling and demonstrate the coupling of nutrient transport with bacterial growth on surfaces. Observatio...
