Instabilities in the fluid mechanics of bacteria

Mercredi 29 mai à 10 h 30 Amphithéâtre Nougaro

Abstract :

Most motile bacteria are equipped with multiple helical flagella, slender appendages whose rotation in viscous fluids allow the cells to self-propel. We highlight in this talk consequences of hydrodynamics for bacteria leading to instabilities. We first show how the swimming of cells with multiple flagella is enabled by an elastohydrodynamic instability. We next demonstrate how interactions between flagellar filaments mediated by the fluid govern the ability of the cells to reorient and lead to flagellar conformation instabilities.
