  1. Is Cinnamon an Effective Bacteria Killing Agent ? Effects of Cinnamon on E-coli and Pseudomonas fluorescence Yaken Ameen Morjan Rahhal

  2. Introduction • Historians have found spices and herbs used as preservatives and medicines since ancient times. [1] • Scientists have found direct correlation between increasing concentrations of cinnamon and the decreasing of bacterial growth rate of E.coli [2] • Our goal was to repeat the experiments found in literature with different techniques and additional bacteria.

  3. Preliminary Experiments: Stage 1 • In our first stage of experiments, we performed triplets of diluted cinnamon concentrations using low salt LB and evaluated growth curves obtained from the using the Bioscreen C.

  4. Preliminary Data: Stage 1

  5. Experiment: Stage 2 In our second stage of experiments, we composed triplet T-streaked, low salt, agar plates with different concentrations of cinnamon.

  6. “Melting” the Cinnamon using the steamer to assure consistency.

  7. Pouring Cinnamon into approximately 70 plates

  8. Plates loaded with 0%-5% Cinnamon Concentrations

  9. Experimental Data: Stage 2

  10. Progression of E-coli death Progression of P. fleur. death

  11. Conclusion:What’s next? Yes, cinnamon is an effective bacterial killing agent when it comes to P.fluorescens and E. coli. What does the future hold? • Testing cinnamon’s antibacterial effects on other bacteria species. • Manufacturing useful antimicrobial products using cinnamon Ex. Soil treatments, food wrapping, gum, toothpaste etc.
