The antimicrobial activities of the essential oils of four different medicinal plants (cumin, thyme, mint and fennel) were investigated on Escherichia coli, Klebsiella pneumonia, Proteus vulgaris, and Pseudomonas aeroginosa. The antimicrobial activity of the essential oils was evaluated by disc diffusion method. The results showed that the most effective oils were thyme (Thymus vulgaris L.) and peppermint (Mintae piperita). The use of these essential oils, should be considered in the food preservation.
