To determine the susceptibility of five Staphylococcus aureus strains to five essential oils and evaluate the anti-biofilm properties of lemongrass and grapefruit essential oils.
Antimicrobial susceptibility of five S. aureus strains was evaluated against five essential oils using the disk diffusion method.
Biofilm inhibition and metabolic activity were measured via colorimetric assays and XTT reduction assays.
Structural disruption of bacterial biofilms after essential oil exposure was visualized using scanning electron microscopy.
All five S. aureus strains were susceptible to lemongrass, grapefruit, bergamot, and lime essential oils (zones of inhibition: 2.85 to 8.60 cm), but resistant to lemon oil.
Lemongrass essential oil inhibited biofilm formation at 0.125% (v/v) and completely eliminated metabolic activity at 0.25% (v/v), whereas grapefruit essential oil exhibited no anti-biofilm activity.
Scanning electron microscopy revealed extensive physical disruption of S. aureus biofilms following exposure to lemongrass essential oil.
