Comparing of Plant Antibacterial Essential Oils With Unique Synthetic Antibiotics on Different Bacteria
S.Sh. Asbaghian*, E.N. Novruzov

In the present investigation antimicrobial activity of three different plant essential oils i.e., Thymus
vulgaris, Th. serphyllum and Mentha longifolia oils have been evaluated. After bioassays, gram-positive
bacteria such as Staphylococcus aureus and Gram-negative bacteria i.e., Escherichia coli and Pseudomonas
aeruginosa were found susceptible to most of the essential oils. For screening of antimicrobial
susceptibility in each essential oil, both positive and negative controls were set to determine MIC (minimum
inhibitory concentration), MBC values (minimum bactericidal concentration) and growth inhibition
zone diameters. Among all essential oils Th. vulgaris oil was found to be highly bactericidal, as it
has shown lowest MIC and MBC values and high growth inhibition zone diameter in comparison to
antibiotics. Present study reveals significantly higher broad-spectrum antibacterial
