Microwave effect on sterilizing bacteria (or virus) by high-power microwaves

In view of the existing situation in conventional sterilization, a special microwave disinfector using high-power microwave energy was made. To detect the microwave effects of disinfection, a series of sterilizing experiments on several typical indicated bacteria (or virus) such as Bacillus subtilis var. nigar, Bacillus stearothermophilus, Bacillus pumilus E₆₀₁, Staphylococcus aureas, Bacillus cereus and HB_ASg were performed by the disinfector. Under the conditions of different sterilization duration and unequal intensity of microwave power irradiation onto the bacteria (or virus), a useful result of killing bacteria has been observed, i.e., the Bacillus subtilis can be considered as an optimum indicated bacterium for microwave sterilization
