Pyrosequencing analysis of bacterial biofilm communities in water meters of a drinking water distribution system

Abstract

The applicability of 454 pyrosequencing to characterize bacterial biofilm communities from two water meters of a drinking water distribution system was assessed. Differences in bacterial diversity and composition were observed. A better understanding of the bacterial ecology of drinking water biofilms will allow for effective management of water quality in distribution systems.

(A and B) Phylogenetic compositions represented by bacterial sequences from water meters WDMS_A (A) and WDMS_B (B). The percentage of bacteria from each division was calculated, and results of ≥3% are shown. The composition and percentage of each bacterial genus are shown in the sector of the respective class of Proteobacteria. (C) Rarefaction analysis of the two water meters at levels of 95 and 97% 16S rRNA gene similarity.
