Biofilms in drinking water distribution systems (DWDSs) could induce several types of problems, including the deterioration of water quality, corrosion of pipe walls and potential proliferation of opportunistic pathogens. However, studies of the effects of abiotic factors on biofilm communities in actual DWDSs have been rare because pipes are not readily accessible. In this study, five biofilm samples from pipes constructed of different materials were collected from an actual DWDS to investigate the effect of pipe material on biofilm bacterial community structure. Real-time quantitative polymerase chain reaction (q-PCR) was used to quantify total bacteria, and culture-based method was used to determine culturable cells and some pathogen species. 454 pyrosequencing was used for bacterial community analysis.
