Biological phosphorus removal lab-scale aerobic granular sludge reactors fed with different influents
The aim was to evaluate the differences in the metatranscriptome of the bacterial community in a laboratory-scale sequencing batch reactor with aerobic granular sludge performing enhanced biological phosphorus removal when different carbon source mixtures were fed. VFA medium contained acetate and propionate (1:1 COD ratio), CM contained acetate, propionate, glucose and an amino acid mixture (1:1:2:2 COD ratio), while CP contained acetate, propionate, glucose, amino acid mixture, starch and peptone (1:1 COD ratio). 2 to 3 cycles and 4 to 6 cycle time points were sampled for each influent, totalling 12 samples per influent.
