Stochastic model for the CheY-P molarity in the neighbourhood of E. coli flagella motors
G. Fier, D. Hansmann, R. C. Buceta
E.coli serves as prototype for the study of peritrichous enteric bacteria that perform runs and tumbles alternately. Bacteria run forward as a result of the counterclockwise (CCW)…
Langevin equations for the run-and-tumble of swimming bacteria
G. Fier, D. Hansmann, R. C. Buceta
The run and tumble motions of a swimming bacterium are well characterized by two stochastic variables: the speed and the change of direction or deflection \mbox{$x(t)=\cosφ(…
New Insights into the Dynamics of Swarming Bacteria: A Theoretical Study
David Hansmann, Guido Fier, Rubén Carlos Buceta
In the present work we simulate the basic two-dimensional dynamics of swarming E. coli bacteria on the surface of a moderately soft agar plate. Individual bacteria are modelled by…
A stochastic model for directional changes of swimming bacteria
G. Fier, D. Hansmann, R. C. Buceta
In this work we introduce a stochastic model to describe directional changes in the movement of swimming bacteria. We use the probability density function (PDF) of turn angles, mea…
