Antibacterial and Antibiofilm Effect of Low Viscosity Chitosan against Staphylococcus epidermidis

Figure 2

Planktonic growth (CFU mL⁻¹) of S. epidermidis at 0 hours (before incubation) and after 18 hours of incubation in medium with LVC at concentrations ranging from 0.0005 to 0.02% w/v (). Control (C): medium with pH 5.9 without LVC. : reduced CFU mL⁻¹ compared to C and 0 h; ¤: reduced CFU mL⁻¹ compared to C (but not to 0 hours); +: CFU mL⁻¹ corresponding to C.
