Dynamics of a bacterium moving by chemotaxis in its own secretion
If you have a question about this talk, please contact Dr Mark Miller.
The brownian dynamics of a single bacterium coupled by chemotaxis to a diffusing concentration field which is secreted by the particle itself is studied by computer simulations in spatial dimensions d = 1, 2, 3. Both cases of a chemoattractant and a chemorepellent are discussed. For a chemoattractant, we find a transient dynamical arrest until the particle diffuses for long times. For a chemorepellant, there is a transient ballistic motion in all dimensions and a long-time diffusion. These results are interpreted with the help of appropriate arguments and theoretical analysis.
