Reduction of P. aeruginosa biofilm formation by combination of ceftazidime (1/16× MIC) and different concentrations of cellulase in PAO1, PA1, and PA2. The error bars indicate the standard deviations between strains. The microplates were incubated for 24 h at 37 °C. Data were normalized to the mean value of the control, which was set at 100%. The error bars indicate the standard deviations between bacteria. Results were expressed as percentage of biofilm biomass formed with respect to control. The statistical significance of the data was determined by an analysis of variance (ANOVA) test followed by the Tukey-Kramer multiple comparison test. Significance was accepted when the P-value was < 0.05 (****P < 0.0001). MIC: Minimum inhibitory concentration
