摘要：
This experimental disinfection was intended to examine the effect of high power microwave on bacteria, and the putative nonthermal effect. The bacteria of the experimental groups were irradiated by high power microwave in different intensities and time and were compared with the controls - bacteria heated only. The principles of disinfection by means of high power microwave were studied. The results showed that the temperature did not change after the dry bacteria were irradiated by high power microwave in different intensities and time, but the number of bacteria alive decreased significantly (P<0.05). The high power microwave's effect of disinfection was grater in the wet bacteria group than in the dry bacteria group and the bacteria heated group. These data indicate that the disinfection effect of high power microwave is higher than that of heating. High power microwave can kill dry bacteria, and it has the nonthermal effect in addition to its thermal effect.
