Figure 7. Disruption of l-serine catabolism perturbs swarming and swimming motility.

Figure 7.

Wild-type P. mirabilis and indicated mutants were inoculated onto the surface of swarm agar plates (A-C) or stab inoculated into motility agar (D-G) as follows: (A, D, and G) standard media formulations; (B and E) media containing 100 μg/mL ampicillin to maintain plasmid selection; (C and F) media supplemented with 10 mM alanine or pyruvate. Motility diameter was measured in millimeters after 16 hours of incubation at 37°C (A-C) or 30°C (D-F). Error bars represent mean ± SD for at least three independent experiments with at least 3 replicates each. *p<0.05, **p<0.01, ***p<0.001 by two-way ANOVA with Tukey’s test for multiple comparisons (A-C) or by one-way ANOVA with Dunnett’s test for multiple comparison (D-G).
