Disruption in Gene Expression Cycles of Polyphosphate Accumulating Organisms is Associated with a Full-Scale Enhanced Biological Phosphorus Removal Instability Event

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
