Inhibition effect of EOs on the growth of (a) S. aureus ATCC 29213 and (b) E. coli ATCC 25922 for MIC₅₀ and MBC determination. Inhibition percentages are presented as the mean ± SD of the absorbance measured at 595 nm with respect to the bacterial growth control. * LTC II (L. origanoides thymol–carvacrol II chemotype), TV (Thymus vulgaris), CN (Cymbopogon nardus), LACI (Lippia alba citral), SO (Salvia officinalis), LTC I (L. origanoides thymol–carvacrol I chemotype), CF (C. flexuosus), LACA (L. alba carvona), LOF (L. origanoides felandreno), CM (C. martini), RO (Rosmarinus officinales), TL (Tagetes lucida), SV (Satureja viminea), CO (Cananga odorata), SG (Swinglea glutinosa).
