UV-C, VUV, Ozone 및 Gamma ray에 의한 병원성 미생물의 불활성화

Batch kinetic experiments were conducted to evaluate the disinfection efficiencies of the microorganisms by UV-C, VUV, ozone and gamma radiation. The disinfection efficiency of S. choleraesuis after UV-C irradiation was 99.06% at 5 min exposure. The disinfection efficiency of E. coli K12 after VUV irradiation was 98.88% at 3 min. The ozone disinfection efficiency was 57.81% at 1 min for S. aureus. The effect of the electron beam irradiation was 99.70% at 2kGy for B. subtilis spores. The results of SEM and TEM indicated that gamma radiation showed more complete destruction of the wall of the microorganisms than other AOPs.
