Granular activated carbon (GAC), a porous carbon-based material, provides increased attachment space for functional microorganisms and enhances nitrogen removal by facilitating extracellular electron transfer in the anammox process. This study investigates effects of GAC on biosynthesis microbial secretions (MESs) explores roles these activities. Four lab-scale reactors were operated: two downstream UASB (D1 D2) receiving effluents from upstream (U1: no-GAC, U2: yes-GAC). Our results indicate that MESs enhanced with addition GAC. The effluent U2 exhibited 59.62 % higher amino acid content than U1. These contributed to an increase loading rate (NLR) reactors. Specifically, NLR D1 130.5 142.7 g N/m3/day, D2, it escalated 137.5 202.8 likely through acting as cross-feeding substrates or vital nutrients. D2 also showed bacterial activity, enriched Ca. Brocadia population hao gene abundance. Furthermore, this revealed sludge has significantly polymeric substances (EPS) (48.71 mg/g VSS) larger average granule size (1.201 ± 0.119 mm) compared sludge. Overall, GAC-stimulated may have performance
