FIG. 7.
Effect of DNase I on biofilm formation by the wild type (LT11) and the comGB mutant (SM015) in the absence or presence of 1 μM SCSP. Biofilm formation was monitored after 48 h by measuring the cell density of resuspended cells (OD600). DNase I was added at 960 U/ml. The results are mean values and standard errors from two independent experiments with two parallels.
