Sewer microbiomes shape microbial community composition and dynamics of wastewater treatment plants.

ABSTRACT: The link between the sewer microbiome and microbial communities in activated sludge wastewater treatment plants is currently poorly understood despite the systems being directly interconnected. Microbial immigration from wastewater has been identified as a key factor determining activated sludge community assembly. Here, we present the first comprehensive study of the sewer microbiome and hypothesize that the microbiome harbors process-critical activated sludge microbes and is thus critical for activated sludge community assembly and performance. We integrated species-level microbial analyses of biofilm, sediment, and sewer wastewater in domestic gravity and pressure sewers in Aalborg, Denmark, with samples from influent wastewater and activated sludge from two downstream wastewater treatm
