This study evaluated the efficiency of aerobic granular sludge (AGS) technology in treating wastewater contaminated with tetracycline (TC), a common antibiotic. AGS was cultivated under TC pressure gradient ranging from 5 mg/L to 15 and compared conventional conditions. The results demonstrated that achieved high removal efficiencies exhibited robust sedimentation performance, significant differences average particle sizes observed both conditions (618.6 μm vs. 456.4 conditions). Importantly, exposure found alter composition production extracellular polymeric substances (EPSs), thereby enhancing structural integrity functional stability AGS. Additionally, selective induced shifts microbial community composition; Rhodanobacter played crucial role EPS biological aggregation, metabolic AGS, while Candida tropicalis remarkable resilience nutrient stressful environmental These findings underscore potential as promising solution for advancing treatment methods, thus contributing protection sustainability amid growing concerns over antibiotic contamination.
