Balancing chemical enhancement and biological inhibition: Unraveling the metabolic trade-offs in iron-dosed denitrifying phosphorus removal systems Raw sequence reads
Five activated sludge samples were collected from a lab-scale anaerobic/anoxic sequencing batch reactor (A/A SBR) for denitrifying phosphorus removal (DPR) under long-term Fe(III) stress (0, 10, 15, 20, 25 mg/L). High-throughput 16S rRNA gene sequencing (V3-V4 region, Illumina MiSeq PE300) was performed to analyze microbial community succession and functional shifts.
