In this work, inhibitory effect of Allium ampeloprasum and two onions (Allium cepa), Junski Srebrnjak and Kupusinski Jabucar, essential oils in different concentrations (1, 4, 7, and 10%) on three yeasts (Saccharomyces cerevisiae, Candida tropicalis, and Rhodotorula sp.) and three moulds (Aspergillus tamarii, Penicillium griseofulvum and Eurotium amstelodami) was investigated. All three essential oils showed the strongest inhibitory effect against S. cerevisiae in concentration of only 1%. Among onions, Kupusinski Jabucar essential oil had stronger influence to C. tropicalis, while Allium ampeloprasum essential oil did not show any influence on this yeast. Rhodotorula sp. was influenced only by Allium ampeloprasum essential oil. The strongest inhibitory effect on A. tamarii showed Kupusinski Jabucar (57% of inhibition, in concentration of 10%), while on P. griseofulvum, the strongest influence showed Allium ampeloprasum essential oil (78.3% of inhibition, in concentration of 10%). Junski Srebrnjak and Kupusinski Jabucar essential oils, in concentrations of 7 and 10% respectively, completely inhibited the growth of E. amstelodami.
