Türkiye ve Suriye'den toplanan aromatik birkilerin antimikrobiyal özellikleri

This study was carried out to determine the antimicrobial properties of aromatic plant essential oils; thyme, anise, mint, chamomile, and basil were collected from Gaziantep in Turkey and from Aleppo and Idleb in Syria. The essential oils were assayed against following microorganisms: Escherichia coli, Salmonella enterica subsp. enterica ser. Typhimurium, Yersinia enterocolitica, Pseudomonas aeroginosa, Listeria monocytogenes, Shigella dysanteria, Staphylococcus aureus, Bacillus cereus, Bacillus subtilis, Klebsiella pneumoniae, Enterococcus faecalis, Streptococcus thermophilus, Saccharomyces cerevisiae, Candida rugosa, Aspergillus flavus, Aspergillus ochraceus, Aspergillus niger, Penicillium expansum, Rhizopus oryzae and Fusarium graminearum.. The MIC (minimal inhibitory concentration), MBC (minimal bactericidal concentration), and MTC (maximum tolerance concentration) were determined for these five types essential oils against the microorganisms. The MIC values for thyme essential oils ranged from 0.1 to 1.25 µg/ml while the MBC from 0.5 to 1.75 µg/ml. For anise essential oil MIC values varied from 5 to 70 µg/mL while the MBC from 10 to 80 µg/ml. For mint essential oils the MIC ranged from 10 to 90 µg/mL while the MBC from 20 to 100 µg/mL. For chamomile essential oils the MIC ranged from 2.5 to 125 µg/mL while the MBC from 2.5 to 130 µg/ml. For basil essential oils the MICranged from 7.5 to 60 µg/mL while the MBC from 10 to 75 µg/ml. The MIC/MBC ratio for essential oils obtained from Turkey and Syria plants is closed to 1. On the other hands, the Turkish and Syrian essential oils have a more antimicrobial effect on selected microorganisms than other species essential and the Syrian basil has higher MIC means than essential oils of species that extracted from the neighbor cities (Gaziantep in Turkey and Aleppo and Idleb in Syria) have similar compounds so, they have similar antimicrobial effect.
