Abstract

For investigation of the food safety and influence of biofilm on the bacterial quality of tap water, it was detected by selective media, and identified by API kit and MIDI system. Biofilm and effluent showed much more colonies than influent. Although there were many presumptive positive colonies, no pathogenic bacterium detected. However opportunistic pathogens, such as Pseudomonas aeruginosa and Aeromonas species, and members of family Enterobacteriaceae were detected. Compared to influent, biofilm and effluent showed more diverse bacteria. This study implies that there would be the negative influence of biofilm on the bacterial qualities of tap water.
