摘要
采用脉冲强光杀菌输入能量为700J,光脉冲宽度小于800μs,当闪照次数多于30次时间使枯草芽孢力,酵母为10^5个/ml减少到0个,在一定时间内,分段照射剂杀菌效果影响不大,杀菌作用的主要波段可能是紫外线,脉冲强光不改变菌液的电导率,使其电位有较大的改变。
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.
