- Assays were performed in triplicate and results are the mean of three values ± standard deviation
- Different letters in superscript to numerical data indicate significant differences (p value < 0.05)
- aZoI: diameter of inhibition zone obtained after 24 h of incubation in agar well diffusion assays. ZoI < 10 mm: low antimicrobial activity; 11 < ZoI < 15 mm: middle antimicrobial activity; ZoI > 16 mm: high antimicrobial activity
