FIG 7.
Comparison of sensitivity of wild type and rsaF mutants to different antimicrobials using an agar disk diffusion assay. Diameters of zones of inhibition are shown in millimeters. Tet, tetracycline; Cd, cadmium sulfate; U, uranyl nitrate; SDS, sodium dodecyl sulfate; H2O2, hydrogen peroxide; wt, wild type. Error bars represent standard deviations from three biological replicates. Mutants showing a significant increase in diameter compared to that of the wild type are highlighted with asterisks (*, P < 0.02; **, P < 0.01).
