Figure 5

BTCs of P. putida F1 and microspheres at the flow velocity of 1.9 m/d. Bacterial and microsphere abundances are normalized to the initial concentrations in the injectates. (a) BTCs of chemotactic bacteria and microspheres for an initial acetate concentration of 0.1 mM. Circles represent chemotactic bacterial data and the bold line is the simulated model. Squares represent microsphere concentration data and the dashed line is the simulated result. (b) BTCs of the nonchemotactic control and microspheres under the same condition as (a) where crosses represent the nonchemotactic bacterial data. Data represents a compilation of two (a) or three (b) replicate experiments, with different symbols representing each replicate.
