The objective of this research was to assess the relevance of organisms related to Rhodocyclus in enhanced biological phosphorus removal in full-scale wastewater treatment plants. The presence of these organisms in full-scale plants was first confirmed by fluorescent in situ hybridization. To address which organisms were involved in phosphorus removal, a method was developed which selected polyphosphate-accumulating organisms from activated sludge samples by DAPI staining and flow cytometry. Sorted samples were characterized using fluorescent in situ hybridization. The results of these analyses confirmed the presence of organisms related to Rhodocyclus in full-scale wastewater treatment plants and supported the involvement of these organisms in enhanced biological phosphorus removal. However, a significant fraction of the polyphosphate-accumulating organisms were not related to Rhodocyclus.
