Nitrite-oxidizing bacteria (NOB) seriously threaten the partial nitritation and Anammox (PN/A) process, hindering its mainstream application. Herein, a one-stage PN/A reactor was continuously operated for 245 days under nitrogen loading rate lifted from 0.4 g N/L/d to 0.6 0.8 with removal efficiency of 71 %, 64 41 respectively. Furthermore, NOB species over time identified as Nitrospira_sp._OLB3, exhibiting an increase relative abundance 0.9 % 4.3 %. The hydroxyapatite (HAP) granules gradually lost their microbiological function then aged, leading dominance. Therefore, one "pulse therapy" introduced combined "continuous enhancement" sludge supported by sidestream competitively limit dynamics. treatment's effect persisted around two months. strategy that returning at least 50 impaired HAP granular recultivation could fulfill bottlenecks PN/A.

Anammox is an energy-efficient nitrogen removal process in which anammox bacteria (AnAOB) oxidize NH4+-N to N2 using NO2--N as the electron acceptor. Recent evidence suggests that AnAOB can perform extracellular transfer (EET), potentially coupling Fe(III) reduction with oxidation (Feammox). However, whether directly participate Feammox within complex wastewater treatment systems remains unclear. Here, we investigated iron-mediated metabolism pathways a microaerobic granular sludge (MGS) reactor by integrating enzyme inhibition assays analyses of gene dynamics and co-occurrence patterns nitrogen- iron-cycling genes. Results demonstrate contributed activity. The iron CT573071, coding porin-cytochrome c protein associated EET, co-occurred hao, hzsABC, hdh genes Candidatus Kuenenia, suggesting its role Feammox. Furthermore, four high-quality metagenome-assembled genomes (MAGs) affiliated Kuenenia stuttgartiensis_A harbored hao-like, genes, along hao-cluster, catalyzes hydroxylamine. This genomic further supports their dual metabolic capacity. Metatranscriptomic analysis confirmed CT573071 upregulation coexpression These findings establish potential K. Feammox, providing novel insights into low-strength systems.
