Figure 2. Effect of volatile organic compounds produced by Bacillus amyloliquefaciens SQR-9 on the motility traits of Ralstonia solanacearum.

Figure 2

(A) Swarming motility; (B) Swimming motility; (C) Chemotaxis; (D) Twitching motility. White arrows indicate the wider peripheral colony fringe of Ralstonia solanacearum in control while black arrows indicate the small peripheral colony fringe of Ralstonia solanacearum after exposure to the VOCs of SQR-9. Error bars indicate standard deviations of three replicates and different letters describe significant differences as determined by student’s t-test at P = 0.05 within the same data group.
