Metabolic Response of "Candidatus Accumulibacter Phosphatis" Clade II C to Changes in Influent P/C Ratio.

ABSTRACT: The objective of this study was to investigate the ability of a culture highly enriched with the polyphosphate-accumulating organism, "Candidatus Accumulibacter phosphatis" clade IIC, to adjust their metabolism to different phosphate availabilities. For this purpose the biomass was cultivated in a sequencing batch reactor with acetate and exposed to different phosphate/carbon influent ratios during six experimental phases. Activity tests were conducted to determine the anaerobic kinetic and stoichiometric parameters as well as the composition of the microbial community. Increasing influent phosphate concentrations led to increased poly-phosphate content and decreased glycogen content of the biomass. In response to higher biomass poly-phosphate content, the biomass showed higher spec
