Abstract

Heat sterilized essential oils (EO), peppermint (Menthe plperita), lemon (Melissa °Manes), clove (Syzgium aromaticum), olive (O/ea europaea), garlic (Allium sativum) and black seed (Nige/la saliva) 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 Nucor sp., Fusarium sp., Aspergillus ochraceus, Aspergillus terrus, Aspergillus Ver, and Aspergillus lumigatz/s. The sterilized clove oil exerted the most potent antifungal activity among the other tested essential oils. Complete fungal inhibition of sterilized dove oils was detected at 2% while strong inhibition was found at 1 %. The antifungal activity of heat sterilized and unsterilized dove oils was evaluated at concentrations of 0.1, 0.3, 0.5, 0.7 and 1.0 0/0 of the fungal medium used. It was found that 0.7 % of unsterilized dove oil showed the strongest fungal inhibition.
