Some heterotrophic denitrifiers exhibit phosphorus
storage in excess of their metabolic requirements
through poly-P synthesis under either aerobic or
anoxic conditions, without the need for alternating
anaerobic/aerobic switches (Barak and van Rijn,
2000a). Unlike PAO, these denitrifiers were unable
to use PHA as an energy source for poly-P synthesis
and derived energy from oxidation of external carbon
sources. The feasibility of this type of phosphate
removal was demonstrated for freshwater as well as
marine recirculating systems (Barak and van Rijn,
2000b; Shnel et al., 2002; Barak et al., 2003; Gelfand
et al., 2003).
