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

Slide 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.
Slide 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.
Experiment: Stage 2 In our second stage of experiments, we
composed triplet T-streaked, low salt, agar plates with different
concentrations of cinnamon.
Slide 6
Melting the Cinnamon using the steamer to assure
consistency.
Progression of E-coli death Progression of P. fleur. death
Slide 11
Conclusion: Whats next? Yes, cinnamon is an effective bacterial
killing agent when it comes to P.fluorescens and E. coli. What does
the future hold? Testing cinnamons antibacterial effects on other
bacteria species. Manufacturing useful antimicrobial products using
cinnamon Ex. Soil treatments, food wrapping, gum, toothpaste
etc.
