Abstract Phosphorus accumulating organisms (PAOs) are the group of microorganisms primarily responsible for removing phosphorus from wastewater in the Enhanced Biological Phosphorus Removal (EBPR) system. Accumulibacter is currently recognized as the main class of PAOs, which contains several clades. Their metabolic characteristics are different. Although PAOs can not be cultured independently, some kind of clades can be selectively enriched under certain conditions. This paper summarized the specific clades and enrichment conditions of Accumulibacter in the EBPR system, and the metabolic characteristics of different clades were analyzed. The relationship between the main clade of Accumulibacter and other microorganisms in the EBPR system was also analyzed in order to provide reference for deeply understanding of biological phosphorus removal microphysiological ecology, as well as solving the problem of deterioration of phosphorus removal or effluent fluctuation in the simultaneous nitrogen and phosphorus removal wastewater treatment systems.
