Biofilms in drinking water distribution systems

Effect of sodium hypochlorite on typical biofilms formed in drinking water distribution systems.

Human health and biological safety problems resulting from urban drinking water pipe network biofilms pollution have attracted wide concern. Despite the inclusion of residual chlorine in drinking water distribution systems supplies, the bacterium is a recalcitrant human pathogen capable of forming biofilms on pipe walls and causing health risks. Typical drinking water bacterial biofilms and the...

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

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.

Mycological Examination and Biofilm Formation in Drinking Water

This study reports the presence of filamentous fungi (ff) in drinking water including biofilms. Ff are not studied sufficiently in drinking water. Ff were highest in winter and had an indirect relation with other microorganisms. Pathogenic fungi were not observed at the mesophilic temperatures used. Penicillium expansum and P. brevicompactum were observed which may affect biofilms by mycotoxin ...
