From: rpoS-mutation variants are selected in Pseudomonas aeruginosa biofilms under imipenem pressure
Hyperbiofilm variants prevail in biofilm competitions. A–F The competition of ancestor and hyperbiofilm variants in planktonic cultures and biofilms when inoculated at the same ratio (A–C) or ancestral: hyperbiofilm mutant = 5:1 (D–F). G Disc diffusion antibiotic sensitivity testing, H growth curves measurement, and I biofilm growth curve was measured. Data are presented as the mean ± s.d. of four biological replicates. Significance was determined using a Student’s t test: n.s indicates no significant difference (P ≥ 0.05); ***P < 0.001
