Abstract :

The effects of essential oils (E.O) are nowadays widely used in antibacterial and antifungal field. This work intends to evaluate the inhibitory effects of E.O extracts of leaves and fruits of the dwarf palm (Chamaerops humilis L.) on certain fungal strains from grain storage silos. 6 mold strains were extracted and identified (Aspergillus flavus, Aspergillus niger, Aspergillus ochraceus, Rhizopus stolonifer, penicillium viridicum and Alternaria). Antifungal tests reveal some inhibition of mycelial growth. It is total in the case of Aspergillus niger at a concentration of 2.5 &micro;l/ ml, and Aspergillus ochraceus and Rhizopus stolonifer at a concentration 12.5 &micro;l/ml. Inhibitions larger than 50% were recorded for Penicillium viridicum et Alternaria sp at concentrations of 0.5 &micro;l/ml. Analysis of the antimicrobial power against three yeast species (C. albicans) showed remarkable activity of this E.O.
