AB  - Dwindling water sources increase the need for efficient wastewater treatment. Solardrivenalgal turf scrubber (ATS) system may remediate wastewater by supporting the developmentand growth of periphytic microbiomes that function and interact in a highly dynamic mannerthrough symbiotic interactions. Using ITS and 16S rRNA gene amplicon sequencing, we profiledthe microbial communities of four microbial biofilms from ATS systems operated with municipalwastewater (mWW), diluted cattle and pig manure (CattleM and PigM), and biogas plant effluentsupernatant (BGE) in comparison to the initial inocula and the respective wastewater substrates.The wastewater-driven biofilms differed significantly in their biodiversity and structure, exhibitingan inocula-independent but substrate-dependent establishment of the microbial communities.The prokaryotic communities were comparable among themselves and with other microbiomes ofaquatic environments and were dominated by metabolically flexible prokaryotes such as nitrifiers,polyphosphate-accumulating and algicide-producing microorganisms, and anoxygenic photoautotrophs.Striking differences occurred in eukaryotic communities: While the mWW biofilm wascharacterized by high biodiversity and many filamentous (benthic) microalgae, the agriculturalwastewater-fed biofilms consisted of less diverse communities with few benthic taxa mainly inhabitedby unicellular chlorophytes and saprophytes/parasites. This study advances our understandingof the microbiome structure and function within the ATS-based wastewater treatment process.
