Sulfamethazine (SM2), a prevalent sulfonamide antibiotic, is commonly detected as an environmental pollutant. Microbial degradation serves important approach to treating SM2 contamination. In this study, SM2-degrading strain, identified Bacillus cereus J2, was isolated from the activated sludge that had been cultured using exclusive carbon source, which demonstrated exceptional capabilities. Under optimized conditions (30 °C, initial OD600 = 0.1, pH 8), strain J2 completely degraded 50 mg/L within 36 h. The also showed high efficiency for other sulfonamides, such sulfamethoxazole and sulfadiazine, could grow normally in mixed system containing these compounds. growth kinetics with source conformed well Haldane model (R2 0.925), revealing strain’s maximum specific rate determined be 0.066 h−1 (µmax) at concentration of 51.35 mg/L. Seven intermediate products were TQ-LCMS analysis, suggesting three potential pathways SM2. These findings suggest holds significant promise bioremediation SM2-contaminated environments.
