In: Egyptian Journal of Agricultural Research 2005.v.83(2)Summary: Heat sterilized essential oils (EO), peppermint (Mentha piperita), lemon (Melissa officinalis), clove (Syzgium aromaticum), olive (Olea europaea), garlic (Allium sativum) and black seed (Nigella sativa) at 1, 2 and 3 % of the fungal medium were tested for their antifungal activity towards six isolates recovered from broiler feed mixtures. The fungal isolates were identified microscopically as Mucor sp., Fusarium sp., Aspergillus ochraceus, Aspergillus terrus, Aspergillus niger, and Aspergillus fumigatus. The sterilized clove oil exerted the most potent antifungal activity among the other tested essential oils. Complete fungal inhibition of sterilized clove oils was detected at 2% while strong inhibition was found at 1 %. The antifungal activity of heat sterilized and unsterilized clove oils was evaluated at concentrations of 0.1, 0.3, 0.5, 0.7 and 1.0 % of the fungal medium used. It was found that 0.7 % of unsterilized clove oil showed the strongest fungal inhibition. Key words. Antifungal, Spoilage fungi, Essential oils, Mycotoxins.
