FIGURE 4.

The determination of the Minimum Biofilm Eradication Concentration (MBEC) against the H. pylori biofilm was evaluated by using the AB assay and the CFU counting. Representative image of colorimetric MBEC evaluation by using AB. The black circle indicates the MBEC at 0.96 mg/L against H. pylori 110R (A). The plot displays the percent reduction of AB in H. pylori biofilms at different concentrations of SUNCs compared to the corresponding untreated biofilms (B). CFU count of SUNCs-treated and untreated biofilms (C). Data are presented as the mean of three replicates of three independent experiments. Controls correspond to 0 mg/L.
