Description
This study aims to investigate the behavior of microbial communities under flow conditions in porous, non-homogeneous 3D environments. Indeed, the majority of microbial communities are known to develop in microstructures, such as in soil or lung pores, and are subject to large variations in the concentrations of dissolved elements (O₂, nutrients, etc.). The objective of this study is then to determine how 3D chaotic flow controls microbial motility and colonization.
This work is conducted through the development of a new method for 3D imaging using laser-induced fluorescence and optical index adjustment. Columns of hydrogel beads mimic the porous 3D environment where bacterial strains are injected in a continuous and steady-state flow. Behavior of Pseudomonas putida KT2440 strains are compared to passive (non-swimming) fluorescent beads and solute.
