摘要
采用自主研制的脉冲强光杀菌装置,通过对大肠杆菌的杀菌试验,研究脉冲强光的杀菌影响因素。结果表明:脉冲强光对大肠杆菌有明显的杀菌效果,各因素对脉冲强光杀菌效果影响的主次顺序是:闪照次数>光照强度>菌液透光率>菌液厚度。在光照强度0.5J/cm2,菌液厚度3.4mm,菌液透光率100,闪照16次能达到完全致死。此外,杀菌菌液的物理性质对杀菌效果有较大影响。
In this paper,sterilizing with pulsed light was studied about E.coli.The results showed,that the sterilizing effect is remarkable. The effect order of the factors is that:the flash frequency>light intensity>the bacterium liquid depth>the bacterium liquid transparency.E.coli can sterilized completely with 0.5 J/cm2 and 16 pulsed light flashs. Besides, the physical characteristic takes evident effect.
