Abstract:
The study aimed to determine the antibacterial effect as well as the best concentration on the bacteria Escherichia Coli. This study used the experimental research method. The extraction was done by decoction. The agar diffusion test or the Kirby-Bauer disk diffusion method was used in the experiment. This study was conducted at the laboratory of the College of Veterinary Medicine of Benguet State University, La Trinidad, Benguet on February 4-15, 2013. Findings showed that no concentrations of lemon peel extract used inhibited the growth of Escherichia coli with the same effect as the antibacterial agent, ciprofloxacin. It concluded that, the different concentrations (25%, 50%, and 75%) of lemon peel extract were not effective against the bacteria Escherichia coli.
From the gathered, analyzed and interpreted, the following recommendations are forwarded. The use of different extraction techniques such as steam distillation and solvent extraction in the future studies against Escherichia Coli. To utilize other fruits known to have an antibacterial component against Escherichia coli. The utilization of lemon peel extract against other forms of bacteria. The utilization of other parts of the lemon tree in the study against different forms of bacteria. The use of this study as a basis to validate findings in future researches
