Inhibitory effect of some plant essential oils on growth of Aspergillus niger, Aspergillus oryzae, Mucor pusillus and Fusarium oxysporum

The antifungal effects of sage, rosemary, anise, quinoa and savory essential oils against mycelium growth of Aspergillus niger, Aspergillus oryza, Mucor pusillus and Fusariumoxysporumwere determined in in vitro conditions. While the 10 mu g/ml of savory essential oil showed inhibitory effect against tested fungi, anise oilwas ineffective at the same concentration. The essential oils of savory and sage showed a great inhibitor effects against M. pusillus when compared with other essential oils. The 20 mu g/ml level of savory oil had effective on Aspergillus niger, Aspergillus oryza, Mucor pusillus and Fusarium oxysporum. The essential oils of sage and rosemary were effective on A. oryza, A. niger and Fusarium oxysporumat ligh concentrations (10 and 20 mu g/ml). The essential oil of quinoa showed an antifungal effect at both concentrations (10 and 20 mu g/ml) on all tested fungi. All the tested essential oils showed inhibitory effect against all the selected fungi. (C) 2017 SAAB. Published by Elsevier B.V. All rights reserved.
