Key Points

The objective is to analyze how disruptions in gene expression cycles of PAOs are linked to instability in enhanced biological phosphorus removal.
Examination of gene expression patterns in polyphosphate accumulating organisms (PAOs)
Study of anaerobic/aerobic feast-famine cycles in wastewater treatment
Assessment of EBPR system stability during measured instability events
Disruptions in gene expression cycles correlate with instability in phosphorus removal efficiency
Identified specific conditions leading to PAO enrichment failure
Observed fluctuations in microbial community dynamics during instability events

Implication

Analysis reveals gene expression disruption affects phosphorus removal efficiency in wastewater systems, suggesting ecological balance importance.

Abstract

Enhanced biological phosphorus removal (EBPR) enriches polyphosphate accumulating organisms (PAOs) via alternating anaerobic/aerobic feast-famine cycles to remove phosphorus from wastewater. EBPR can be prone to instability though the causes are...
