Abstract

Essential oils (EOs) are known for their antimicrobial
activities against a broad range of microorganisms. In this study we
investigated if EOs obtained from plants grown by organic farming are more
potent than those obtained from conventional farming, or vice versa. Therefore,
the aim of this study was to compare pairwise the inhibitory
vapor-phase-mediated antimicrobial activity of 33 certified organic EOs and as
many equivalent EOs without such certification against two human pathogenic Candida species using the
vapor-phase- mediated susceptibility assay. Overall, C. glabrata is more susceptible
than C.
albicans to
EOs, but we could not show a significant difference in EO antimicrobial
activity between certified organic and without certification
