In vitro Antimicrobial Activity of Bulgarian Lavender Essential Oil

In vitro studies of the antimicrobial activity of lavender essential oil from Lavandula angustifolia Mill. produced in Bulgaria in 2021 and 2022 by Bioagro Bg Ltd were carried out by determining the minimum bactericidal concentrations (MBC) and minimum fungicidal concentrations (MFC). Sixteen microbial strains of Esherihia coli, Salmonella enterica, Staphylococcus aureus, and Candida albicans were used, respectively, by 1 reference (ATCC) and 3 clinical isolates of each species. A very high antimicrobial activity of the essential oil from both batches was found. MBC and, respectively, MFC for all strains studied were below 0.1125 % (v/v) or 1.009 mg.mL-1.
