Modeling the energy trade-off between glycogen and polyphosphate use in phosphate accumulating organisms

Phosphate accumulating organisms (PAOs) perform a storage polymer metabolism within an anaerobic-aerobic cycle. Anaerobically, PAOs take up volatile fatty acids (VFA) and store them as poly-ẞ-hydroxyalkanoates (PHA). The energy (mainly ATP) necessary for the transport and storage of VFA (and general maintenance) is obtained through the cleavage...
