Phenotypic characterization of both capsule deletion mutants. A. Growth curves for the wild-type (WT), ∆wzabc, and ∆cps strains. B. Measurements of uronic acid content in the wild-type, ∆wzabc, and ∆cps strains. Values were normalized by the optical densities of the samples when the measurements were made. C. The susceptibility of the wild-type, ∆wzabc, and ∆cps strains to hydrogen peroxide (left) and polymyxin B (right). Error bars in all three panels denote the standard deviation of three biological replicates.
