| Περίληψη: | Anaerobic ammonium oxidation (anammox), a sustainable and energy-efficient biological nitrogen removal process, is vulnerable to antibiotic stress during stable operation, while the mechanism of functional recovery mediated by sulfides remains unclear. This study systematically analyzed the response characteristics of the anammox process under sustained high-concentration oxytetracycline (OTC) and sulfamethoxazole (SMX) exposure, and further evaluated the potential of sulfide as an exogenous regulatory factor to mitigate antibiotic stress. Results indicate that sustained high concentration OTC and SMX exposure impaired the system's nitrogen removal performance, while the removal efficiencies of ammonium and nitrite successfully recovered to 85% and 83%, respectively, following sulfide addition. Metagenomic analysis suggested that the addition of sulfide was accompanied by an increased abundance of potential genes related to sulfur and nitrogen metabolism. Moreover, sulfide may alleviate antibiotic stress by facilitating metabolic interactions related to electron transfer and increasing the potential for SMX degradation. Furthermore, under OTC and SMX stress, a 20% increase in the abundance of Brocadia sapporoensis harboring ARGs was closely associated with the addition of sulfide. This study elucidates the biological mechanisms by which sulfides mitigate antibiotic stress, providing a theoretical basis for recovery strategies of anammox under an intensified stress model.
