The antibacterial activity on dried fruit peels of Citrus species were evaluated on bacteria strains like Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa. Methanol, chloroform, acetone and water extracts were used for the present study. The in vitro antibacterial activity was performed by agar disc diffusion method. The study reveals that all the fruit peels extracts were active against E.coli and Staphylococcus aureus followed by the other bacteria. Among all the extracts, Citrus aurantium showed highest activity against all the tested human pathogenic bacteria. But, in the case of methanol extract of fresh peel of Citrus limon showed highly significant activity against all the tested organisms. Pseudomonas aeruginosa and Proteus mirabilis are highly sensitive to the Citrus limon extracts when comparing to the other extracts of fruit peels. Considering about the maximum sensitivity effect of various bacteria against different fruit peels extracts, it becomes very clear that the bacteria Staphylococcus aureus and Escherichia coli were highly sensitive. The result of the study shows that the organic and water extracts were more potent against both the Gram- positive and gram -negative bacteria used for the present study. This study support to a certain extent, the recycling of fruit waste and utilizing it in a number of innovative ways.
