[Display omitted] • Recently identified putative PAOs reveal vast metabolic versatility compared to Accumulibacter. • Electron donors and acceptors drive EBPR community composition and process stability. • EBPR can be employed in the long-term global perspective of rising temperatures. • Hybrid assemblies of long-read and short-read sequences aid study of uncultured EBPR microorganisms. • 16S rRNA primer sets vary in specificity towards EBPR microorganisms. 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. [ABSTRACT FROM AUTHOR]
