Effect of EGCG on biofilm formation by a clinically isolated strain of E. coli. (a) Biofilms of E. coli O157:H7 Sakai were formed in the presence of the indicated concentrations of EGCG and quantified as described in Fig. 2. (b) Effect of EGCG on growth of the strain was investigated at 30 °C in YESCA medium supplemented with the indicated concentrations of EGCG. As a control, 1% DMSO without any compounds was supplemented in the medium. Absorbance at 600 nm every 30 min was measured. The means and standard deviations from at least triplicate determinations are represented.
