This study measured and analyzed the concentration of the microbes contained in the exterior air and interior air of duct of Bio-Filter system installed at KIST utilizing RCS Air Sampler and Blood Agar Petridish(BAP) from 13 September 1993 to 22 December 1993 in order to analyze the sterilizing capability and efficiency against the microbes of Bio-Filter.
As a result of this experimentation, in exterior air and interior air of Bio-Filter system 3 kinds og germ group such as G(+) cocci, G(_) bacilli and G(+) bacilli were cultured and these germs were identified as that they have about ten kinds of characteristics.
By comparision of the number of colony according to the kind of germ, in the exterior air G(+) cocci was cultured to each about 6.75 colonies in average and it was an extreme many, while in the system G(+) bacilli was cultured about 10 colonies before filter and it showed extreme many.
When we check the decreasing rate of the kind of germ before and after operation of Bio-Filter, we can see that G(+) cocci has been decreased by 87.5%, G(_) bacilli by 85.7% and G(+) bacilli by 87.5% respectively.
