Figure 6. Flagella are deleterious for biofilm maturation.

Kinetics of biofilm development for different strains was analyzed by the microtiter assay. Optical densities (OD540) are plotted along the y-axis and time in hours, is shown along the x-axis. Data shown are averages obtained from at least 6 wells each time from 2 independent experiments. The error bars represent +/− the standard error. All differences are statistically significant (p<0.05, student’s t test), except among the strains at 1 h time point and between the strains Rev1Δfla and WT at 48 and 72 hours.
