Evaluation of the Capacity of Phosphorus‐Accumulating Organisms To Use Nitrate and Oxygen as Final Electron Acceptors: A Theoretical Study on Population Dynamics

Ability of phosphorus‐accumulating organisms (PAGs) capable of using both nitrate and oxygen as temlinal electron acceptors to compete successfully in biological excess phosphorus removal (BEPR) systems was assessed relative to purely aerobic PAGs. The anoxic‐aerobic population has a significant competitive disadvantage when competing with PAGs that can only use oxygen because of a lower thermodynamic efficiency of anoxic growth compared to …
