Stoichiometry and kinetics of acetate uptake under anaerobic conditions by an enriched culture of phosphorus‐accumulating organisms at different pHs

The effect of pH on the stoichiometry and kinetics of acetate uptake by phosphorus-accumulating organisms (PAOs) was studied. The stoichiometry of glycogen consumption and poly-beta-hydroxy-alkanoates (PHA) accumulation was independent of the pH over the range 6.5 to 8.0. It was again demonstrated that the amount of phosphorus released per acetate taken up (P/Hac ratio) was linearly dependent on pH, because of additional energy requirements for …
