　　Everyday huge amount of treated municipal wastewater is discharged into the coastal seawater.However, special bacterial biomarkers for the municipal effluent instead of the fecal species from raw sewage have not been proposed.Meanwhile, bacterial taxa that are responsible for degrading large amounts of input organics have not been investigated.We collected raw effluent and serial water samples from the coastal dispersal of two sewage treatment plants in Xiamen, China.Free-living (FL) and particle-associated (PA) bacterial communities were analyzed via high-throughput sequencing of 16S rRNA gene amplicons and qPCR to measure total bacterial abundance.The results indicated that shift in bacterial communities during the coastal dispersal of effluents was primarily driven by residual organic nutrients.
