초록

배급수관망에 사용되는 아연도강관과 탄소강관이, 수돗물속에서 생장시키는 생물막의 세균농도와 미생물군집의 양상을 비교하기 위하여 Biolog GN plate를 이용한 CLPP를 수행하였다. 세균농도는 $10^4\;-\;10^6\;CFU/cm^2$이었고, 탄소강관과 아연도강관에 따른 생물막의 세균농도는 유의한 차이가 없었다. 평균적인 발색양상은 비슷하였지만 개별적인 CLPP 양상은 재질과 시기에 따라 다른 것으로 나타나, 미생물군집의 양상이 시간과 재질에 따라 다른 것을 알 수 있었다.

The effect of pipe materials on biofilm communities were investigated by CLPP (community level physiology profile) using Biolog GN plates. Heterotrophic bacterial concentrations were $10^4\;-\;10^6\;CFU/cm^2$ and there was no differences between galvanized iron and carbon steel. Average optical density of Biolog plate was similar between two pipe materials. However, CLPP was different according to the type of pipe materials and exposed times to tap water, and CLPP was independent of bacterial concentration. This represents the differences of bacterial communities with pipes and water contact times.
