From: Rhamnolipid coating reduces microbial biofilm formation on titanium implants: an in vitro study
Staphylococcus spp. biofilm formation on polished titanium discs coated with 4 mg/mL R89BS (light bars) with respect to uncoated controls (dark bars). Results are presented both in terms of biofilm biomass (a, b), determined by CV assay, and cell metabolic activity (c, d), determined by MTT assay, after 24, 48 and 72 h of incubation. Error bars represent interquartile ranges around median values. *p < 0.05
