  1. Microorganisms were classified on a subjective basis as strong, intermediate, or weak biofilm producers on PS if their absorbance values from CV stains were greater than 0.2, from 0.05 to 0.2, and less than 0.05, respectively. P-value < 0.0001 indicated statistical significance between groups (one-way ANOVA).
