Mihajilov-Krstev, T., Radnovi?, D., Kiti?, D.: Antimicrobial activity of Satureja L. essential oils againstphytopathogenic bacteria Erwinia amylovora . Biologica Nyssana, 1 (1-2), December 2010: 95-98. In this paper, antimicrobial activity of S. kitaibelii Wierzb. ex Heuff., S. montana ssp. montana L., S.adamovicii ?ili? and S. fukarekii ?ili? has been investigated. During the testing, two methods were used:disc-diffusion and broth micro-dilution. The results showed high sensitivity of this bacteria to all fouressential oils. The essential oil of S. montana ssp. montana exhibited the largest inhibition zone (25 mm),while S. adamovicii showed the highest inhibitory and bactericidal activity (MIC=MBC=0.09 μlml-1). Allinvestigated oils showed the same values for MIC and MBC, which means that the oils posses bactericidaleffect at very low concentrations and they could be used as non-harmful source of bactericides.
