Swimming bacteria in Poiseuille flow: the quest for active Bretherton-Jeffery trajectories

Gaspard Junot, Nuris Figueroa-Morales, Thierry Darnige +4

Using a 3D Lagrangian tracking technique, we determine experimentally the trajectories of non-tumbling E. coli mutants swimming in a Poiseuille flow. We identify a typology of traj…
