Figure 4

The effect of the D. tsuruhatensis 11304 QSI extract on P. aeruginosa MMA83 biofilm formation (a,b) and decomposition of preformed biofilms (c,d), captured with fluorescence microscopy. P. aeruginosa MMA83 was coincubated for 24 hours with 5 mg/ml D. tsuruhatensis 11304 QSI extract in order to visualize its effects on biofilm forming ability. The effect of the D. tsuruhatensis 11304 QSI extract on decomposition of 24 hours old preformed biofilm was evaluated after 24 hours of treatment with QSI extract. Fluorescent dyes SYTO9 (green) and PI (red) were used for the visualization of biofilms. Scale bar represents 10 µm.
