Effect of dksA paralogs on H₂O₂ tolerance in P. aeruginosa biofilm. Biofilm biomass (a) and viability (b; expressed as Fluorescence units, F. u.) of the indicated strains grown in M9-glu-CAA supplemented with 0.1 mM IPTG, challenged for 6 h with 5, 10 or 20 mM H₂O₂. The average values from five independent experiments performed on multiple wells per condition are reported with standard deviations. ***p < 0.001 versus untreated wild type (a; ANOVA); *p < 0.05 and ***p < 0.001 versus wild type challenged with 10 and 5 mM H₂O₂, respectively (b; ANOVA).
