| Outline of Final Research Achievements |
We have demonstrated effects of atmospheric pressure plasma generated by superimposed voltage waveform pulsed-power supply on treatment of Escherichia coli (E.coli). The growth rate of E.coli is evaluated with a measurement of optical density. The results show that the growth rate of E.coli with the irradiation of atmospheric pressure plasma without superimposed voltage waveform decreases. On the other hand, the growth rate of E.coli with the irradiation of atmospheric pressure plasma with superimposed voltage waveform is similar to the control condition. These results suggest that the irradiation of atmospheric pressure plasma with superimposed voltage waveform affects the growth rate of E.coli.
