From: Rhamnolipid coating reduces microbial biofilm formation on titanium implants: an in vitro study
S. aureus (a) and S. epidermidis (b) biofilm formation on laboratory polished titanium discs coated by physical adsorption with different concentrations of R89BS (0, 2 and 4 mg/mL). Data are obtained from CV staining after 24 h incubation. Results are displayed with respect to uncoated controls (0 mg/mL), normalized to 100% for ease of comparison. Error bars represent interquartile ranges around median values. *p < 0.05
