FIG 3.

Myr suppresses curli-dependent biofilm formation in E. coli. (A) Chemical structure of Myr is shown. (B) Biofilm of E. coli wild-type strain was formed in YESCA medium supplemented with or without the indicated concentrations of Myr at 30°C for 7 days. A photograph of the 0.2% CV-stained biofilms is shown. (C) CV-stained biofilms shown in panel B were quantified as described for Fig. 1B and in Materials and Methods. (D) Growth of the E. coli wild-type strain was monitored in YESCA medium supplemented with the indicated concentrations of Myr. The means and standard deviations from triplicate determinations are represented.
