N2 - Enhanced biological phosphorus removal (EBPR) is an efficient, cost-effective, and sustainable method for removing excess phosphorus from wastewater. Polyphosphate accumulating organisms (PAOs) exhibit a unique physiology alternating between anaerobic conditions for uptake of carbon substrates and aerobic or anoxic conditions for phosphorus uptake. The implementation of high-throughput sequencing technologies and advanced molecular tools along with biochemical characterization has provided many new perspectives on the EBPR process. These approaches have helped identify a wide range of carbon substrates and electron acceptors utilized by PAOs that in turn influence interactions with microbial community members and determine overall phosphorus removal efficiency. In this review, we systematically discuss the microbial diversity and metabolic response to a range of environmental conditions and process control strategies in EBPR.
