FIGURE 4.
(a) Biofilm thickness and (b) biovolume of S. aureus biofilms treated with vancomycin-only (Va), maltodextrin-only (Ma), or a combination of the two. Time in days indicates the age of the biofilm; treatments were administered after 5 days of growth. The biofilm thickness is averaged throughout the biofilm domain while the biovolume is averaged from five estimates. Error bars represent the standard deviation and some cases they are smaller than the symbols and not visiable
