Effects of polyols on GBS-S19 biofilm formation. Biofilm formation of GBS-S19 in TH broth supplemented with polyols was quantified by crystal violet staining. Biofilm formation was expressed as a fold change in the percent biofilm formation in comparison to control (no polyols). Bars represent the average A595 values obtained from two independent experiments compared with the value obtained from (0%) to determine statistical significance; an asterisk (*) indicates statistical significance (p < 0.05) and (**) indicates (p < 0.01)
