Inhibition Zone. Data are presented as mean of triplicate determinations ± standard deviation (n = 3). MIC: Minimal Inhibitory Concentration. MBC: Minimal Bactericidal Concentration. MFC: Minimal Fungicidal Concentration. The letters (a–c) indicate a significant difference between the different extracts inhibition zone according to the Duncan test (* p < 0.05). *: Not tested.
