Direct measurement of the aerotactic response in a bacterial suspension
J. Bouvard, C. Douarche, P. Mergaert +2
Aerotaxis is the ability of motile cells to navigate toward oxygen. A key question is the dependence of the aerotactic velocity with the local oxygen concentration c. Here we combi…
Dispersion of motile bacteria in a porous medium
Marco Dentz, Adama Creppy, Carine Douarche +2
Understanding flow and transport of bacteria in porous media is crucial to technologies such as bioremediation, biomineralization or enhanced oil recovery. While physicochemical ba…
Run-to-Tumble Variability Controls the Surface Residence Times of Bacteria
Gaspard Junot, Thierry Darnige, Anke Lindner +6
Motile bacteria are known to accumulate at surfaces, eventually leading to changes in bacterial motility and bio-film formation. We use a novel two-colour, three-dimensional Lagran…
Single-Trajectory Characterization of Active Swimmers in a Flow
Gaspard Junot, Eric Clément, Harold Auradou +1
We develop a maximum likelihood method to infer relevant physical properties of elongated active particles. Using individual trajectories of advected swimmers as input, we are able…
The Influence of Motility on Bacterial Accumulation in a Microporous Channel
Miru Lee, Christoph Lohrmann, Kai Szuttor +2
We study the transport of bacteria in a porous media modeled by a square channel containing one cylindrical obstacle via molecular dynamics simulations coupled to a lattice Boltzma…
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…
