Increasing eutrophication has led to a continuous deterioration of many aquatic ecosystems. Polyphosphate-accumulating organisms (PAOs) can provide insight into the human response this challenge, as they initiate enhanced biological phosphorus removal (EBPR) through cyclical anaerobic release and aerobic uptake. Although limiting environmental factors for PAO growth have been widely discussed, there remains gap in knowledge surrounding differences type efficiencies natural engineered systems. Furthermore, due limitations PAOs conventional wastewater treatment environments, is an urgent need find functional extreme environments better treatment. Therefore, it necessary explore effects conditions on efficiency well types, sources, characteristics PAOs. In paper, we summarize mechanisms PAOs, denitrifying polyphosphate-accumulating (D-PAOs), (AD-PAOs), sulfur-related (S-PAOs). The mechanism nitrogen related coupling cycles carbon, nitrogen, phosphorus, sulfur. genera differ systems, but more diversity soils. Recent studies impact several parameters (e.g., temperature, carbon source, pH, dissolved oxygen) extracellular polymer substances systems are further discussed.
