Abstract: Sterilizing with pulsed light was studied. The results showed that the main factors affecting sterilizing effect were amount of pulsed light flashs, input voltage, the initial concentration Of microorganisms. More than30 pulsed light flashs can kill Bactillus subtilis, yeast from 10~5/ml to 0. The band mainly deciding sterilizing effect was probably ultraviolel wavelenths. Sterilizing with pulsed light did not caused change in specific conductance but cause change in potential.
