Antibacterial and Antibiofilm Effect of Low Viscosity Chitosan against Staphylococcus epidermidis

Figure 5

Biofilm of S. epidermidis stained with safranin after 6-hour (a) and 18-hour (b) incubation on polystyrene discs coated with LVC (0.25, 0.5, and 1% w/v) (). Amount of biomass is expressed as optical density (OD₅₃₀) relative to control (C). Control: discs coated with 0.5% HCl. : OD₅₃₀ significantly reduced compared to C.
