    Abstract: "In this paper, the movement of bacteria, i.e. E. coli, is
    simulated based on the run and tumble model. The random walk
    parameters, such as the speed, tumbling frequency, run duration,
    and the turn angle between two successive runs were taken from
    experimental measurements; and use them to simulate the bacteria
    movement in cases of three different uniform chemical
    concentration distributions. The motility coefficient is computed to
    characterize the migration responses. Furthermore, a case of
    chemical attractant gradient distribution in the environment is
    designed to validate the run and tumble model. It is found that
    bacteria move with higher motility coefficient in higher chemical
    concentrations. Simulation results suggested that bacterial run and
    tumble model can be used to describe real bacteria movement. "
