Molecular monitoring of microbes in surface water and distribution system of pipeline using PCR-DGGE
The objective of this study is to monitor the microorganisms in various surface water and distribution system of pipeline in the use of Denaturation Gradient Gel Electrophoresis (DGGE) system.
Five major surface water (GR, DH, BS, IS, CJ) and two samples of distribution system (DB, US) in the pipeline were used. Nucleic acids of these samples were amplified using PCR and confirmed by DGGE using 8% polyacrylamide gel. The microbial communities of samples which were taken in November were more diverse than in August in 2010. The microbial community in the distribution system was also observed and compared with the data from surface water. The diversity of microbial community in the distribution system is less than that of surface water. The PCR-DGGE methods can be used as a useful tool to compare the microbial community and expect the variation of microbial community.
