To test and verify the results of bacteria sterilization with plasma and to analyze the inactivation mechanisms,we get results of a series of experimentations by E.coli treated with two plasmas-DBD plasma jet and APMTP+JET plasma.We obtain the life curves of E.coli(Escherichia coli)by taking account of the bacteria nurtured in medium after being treated,and compare SEM(scanning electron microscopy) photographs taken before and after experimentation.It is found that the microwave plasma works better than DBD plasma jet does;the life curves show different regulations when treated by different plasma;active base and high-energy nuclear physics probably play an important role in experiments,and accumulated electrostatic charge takes effect;for microwave plasma,the high-temperature can not be ignored;other factors work in coordination.
