Time series of biological phosphorus removal lab-scale reactor
The aim was to follow the changes in the metatranscriptome of the bacterial community in a laboratory-scale sequencing batch reactor performing enhanced biological phosphorus removal. The biomass was enriched with Accumulibacter. The carbon sources supplied were acetate and propionate (1:1 COD ratio, 600 mg COD/L, COD/P ratio of 12) and allylthiourea was added to inhibit nitrification. Ten samples were taken during the operation cycle, from the beginning of the cycle until the end of the aerobic phase. Three cycles were sampled as biological replicates, giving a total of 30 samples.
