Antimicrobial effect and mechanism of cinnamon oil and gamma radiation on .

The aims of this study were to observe the antimicrobial effect and mechanism of cinnamon oil combined with gamma radiation on Gamma radiation increased the antimicrobial activity of cinnamon oil, and the relative radiation sensitivity of gamma radiation on was increased by cinnamon oil. Gamma radiation significantly increased the changes of bacterial morphology, intra-adenosine 5'-triphosphate (intra-ATP) and extra-ATP concentrations and pH value of treated cinnamon oil. Although, gamma radiation used alone didn't damage the bacterial morphology and ATP concentrations significantly.
