The aim of this study was to determine the sensitivity profile of mould strains isolated from foods to some essential oils and phytochemicals. The assayed mould strains were: Fusarium spp., Rhizopus spp., Aspergillus flavus, A. niger and Penicillium spp. According to results, Lippia alba N.E. Brown, Peumus boldus Molina, Lippia microphylla Phil., Citrus limon Risso and Cymbopogon citratus Stapf. essential oil and the phytochemicals citral, eugenol and mircene showed prominent antimould activity. Among the products that evidenced antimould activity, citral and eugenol showed the lowest minimum inhibitory concentrations, which was 1% and 4%, respectively, for the most of the tested mould strains. |

Dematiaceous moulds are pathogen microorganisms able to act as etiological agents of mycoses with different degrees of severity. This study evaluated the effectiveness of Cinnamomum zeylanicum Blume essential oil and beta-pinene in inhibiting the growth of various strains of dematiaceous moulds (Alternaria brassicola, Cladosporium herbarium, C. resinae, C. cladosporioides, Chaetomum globosum, Curvularia sp., Fonsecaea compacta, Piedraia hortae). Antimicrobial assays were led by determining the Minimum Inhibitory Concentration-MIC using the solid medium diffusion procedure and observing the interference of the MIC values on the mould radial mycelial growth along 14 days. MIC values found to C. zeylanicum essential oil oscillated between 63 and 125 µL/mL.... |
