The antibacterial effect of citrus peel lemon against the bacterial strains obtained from the filters of air conditioners have been selected based on the presence most in these filters such as Streptococcus, Bacillus spp, Pseudomonas, E coli. agar well diffusion method used to evaluate antibacterial activity of citrus peels water extract. through the results became clear to us that the cold aqueous extract of lemon peel showed a significant effect on the growth of bacterial species through the diameters of inhibition zone that appeared in all concentrations of the extract (125, 250, 500, 1000) mg/ml. Gram-positive bacteria Streptococcus spp were the most affected Where the diameters of inhibition zone (18, 15, 12, 0, 0) mm respectively, while The Gram-negative bacteria E coli least affected. The results obtained in this study indicate that citrus lemon peel can be used in the treatment of diseases caused by organisms for the purposes of the pharmaceutical.
