Quantification of viable cells of mono- and polymicrobial biofilms from a CDC biofilm reactor using three different coupon surfaces (panel A) and the same surfaces grown in a static way (panel B). Results display the mean ± SD (error bars) of three independent experiments. Statistical analysis was by one-way analysis of variance (ANOVA) with Holm–Sidak test. p-value < 0.001. Significant differences are reported with a = polypropylene vs. Teflon, b = polycarbonate vs. Teflon, and c = polypropylene vs. polycarbonate.
