Sterilization effects of the pulsed magnetic field with a maximum intensity of 11.37 Tesla were investigated on Escherichia coli AS 1.129, Staphylococcus aureus AS 1.89, Saccharomyces cerevisiae ATTC 7552 and Bacillus subtilis AS 1.921. The well-regulated fluctuations of sterilization effects with magnetic field intensity and pulse number were observed, and can be described by the "window effect" of magnetic fields and provide a better explanation of the inconsistent results of PMF sterilization in published literature. Sensibility of bacteria on the pulsed magnetic field significantly depends on a variety of microorganisms. Sterilization effects of a flowing sample were better than that of static samples.

Keywords: magnetic field; pulse; sterilization; window effect
