TolC Promotes ExPEC Biofilm Formation and Curli Production in Response to Medium Osmolarity
Figure 5
Effect of TolC on the production of curli fimbriae as determined by Congo red binding. All strains were cultivated on M9 agar plates (a) or 1/2 M9 agar plates (b) supplemented with Congo red at 28°C for 5 days. Visible Congo red binding was observed by the naked eye.
