Effect of indole (500 μM) on the motility of BW25113 wild-type (W/T), BW25113 trpE, BW25113 tnaC, BW25113 tnaA, and BW25113 sdiA. Motility halos were measured at 8 h. Each experiment was repeated two or four times, and one standard deviation is shown. DMF (0.1 %, v/v) was used as a negative control.
