Antimicrobial and Anti-Biofilm Effects of Mentha piperita and Zataria multiflora on Pathogenic Bacteria

The aim of this study was to investigate the antimicrobial and anti-biofilm effects of Mentha piperita and Zataria multiflora on some pathogenic bacteria. Mentha piperita and Zataria multiflora essential oils were obtained by using the clevenger device. The bacterial cultures were prepared as standard samples. Finally, antimicrobial and anti-biofilm activity was determined by microdilution method. The results of this study showed that the lowest inhibitory concentration of essential oil of Zataria multiflora was 1.25 mg / ml, while the rest of the bacteria were inhibited at a concentration of 2.5 mg / ml. The lowest and highest inhibitory concentrations were found as 1.25 and 5 mg / ml against Pseudomonas aeruginosa. The results of the study showed that Z. multiflora essential oil showed antimicrobial and anti-biofilm activity that could be used to treat infections caused by these bacteria.
