Oils of citrus peels contain a chemical which has exhibited insecticide properties. Citrus oils might also have natural antibiotic or antifungicide properties which could prove beneficial to mankind. The purpose of this project was to analyze the possible inhibition of microorganisms by oils of citrus peels. Five citrus fruit peels were tested for bacterial or fungal inhibition on Escherichia coli, Bacillus cereus and Aspergillus niger. Oils of lemon peel showed an inhibition zone on the A. niger in the first trial. In the second experiment, all of the citrus peel oils showed an inhibition zone on the A. niger. The bacteria showed no inhibition by the oils.
