Potential shift of bacterial community structure and corrosion-related bacteria in drinking water distributionpipeline driven by water source switching

Yue Hu, Ding Dong, Kun Wan, Chao Chen, Xin Yu, Huirong Lin

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 2, doi: 10.1007/s11783-020-1320-3

Abstract: As a result of pollution in the present water sources, cities have been forced to utilize cleaner waterThree types of finished water were used for simulation, the polluted source water from the Qiantang andDongtiaoxi Rivers (China) was replaced by cleaner water from Qiandao Lake (China).The bacterial community released from the pipeline reactor was significantly different under differentfinished water, and it exhibited large variation at the genus level.
