Staphylococcus spp. biofilm disruption by R89 biosurfactant (R89BS). S. aureus and S. epidermidis pre-formed biofilms were co-incubated with R89BS at concentrations ranging from 0.06 to 2 mg/mL. The disrupting activity of R89BS on Staphylococcus spp. biofilms was evaluated after 24 h at 37 °C. Dots (six for each concentration) represent single experimental data.
