Directional persistence and the optimality of run-and-tumble chemotaxis.

Abstract:

E. coli does chemotaxis by performing a biased random walk composed of alternating periods of swimming (runs) and reorientations (tumbles). Tumbles are typically modelled as complete directional randomisations but it is known that in wild type E. coli, successive run directions are actually weakly correlated, with a mean directional difference of approximately 63 degrees. We recently presented a model of the evolution of chemotactic swimming strategies in bacteria which is able to quantitativ...
