READ ME This text describes the data presented in the paper: "Coupled virus - bacteria interactions and ecosystem function in an engineered microbial system" ======================== Introductory information ======================== Data from a two year time series of weekly samples collected from a full scale, nitrifying activated sludge system are collated. It includes generic wastewater chemistry and plant operational conditions, 16s sequencing and total bacterial, ammonia oxidising bacterial and virus abundances. Files included in the data deposit: 1)Read me file 2)Abundance, Physio-chemical and Operational Data 3)Link to projects sequencing data uploaded to the ENA (Project: PRJEB48758) Key words used to describe the data: Activated Sludge, Viruses, Bacteria, Wastewater ========================== Methodological information ========================== See original manuscript.
