The investigation of antimicrobial activity of thyme and oregano essential oils

摘要: The aim of this study is to investigate in-vitro antimicrobial effects the essential oils from oregano (Origanum acutidens and Origanum rotundifolium) thyme (Thymus sipyleus subsp. var. rosulans). chemical composition attributes obtained aerial parts plants, which there were 3 Lamiaceae species, have been studied. A total 43 microorganisms, including 26 bacteria, 14 fungi, yeasts studied by using disc-diffusion (DD) minimal inhibition concentration (MIC) methods. Mean zones MIC values bacterial strains varied 8 72 mm 7.8 500 µg mL-1, respectively. maximal yeast fungi species sensitive 8-74 7.8-500 susceptibility tested microorganisms depending on oil composition. In general, showed higher DD than antibiotics. may be considered a potential source natural for food industry after testing toxic irritating humans.
