【 摘 要 】

Penicillin-G was detected in drinking water by LC-MS/MS and the bacterial diversity was investigated by PCR and high-throughput sequencing. The results showed that bacteria community structure in drinking water has undergone major changes when added different concentrations of penicillin-G. The diversity index of each sample was calculated. The results showed that the total number and abundance of bacterial community species in drinking water samples decreased significantly after the addition of penicillin-G. However, the number and abundance of community structure did not change with the concentration. Penicillin-G inhibits the activity of bacterial community in drinking water and can reduce the bacterial diversity in drinking water.
