N2 - Antibiotics are used in animal agriculture for disease treatment, and it has been discovered that 70-90% of the antibiotics are excreted either in their original form or as active metabolites (Massé et al., 2014). Despite the advantages of manure application on crops as fertilizers, it is crucial to acknowledge the escalating ecological risks with antibiotic residues. Antibiotics, characterized as pseudo-persistant pollutants, pose a persistent threat. Prolonged exposure to these substances may result in the development of chronic toxicity in organisms, consequently fostering antibiotic resistance (He et al., 2016; Tian et al., 2023). With manure treatment and antibiotic degradation before manure application on crops, antibiotic and antibiotic resistance spread can be limited. This research is the first to investigate antibiotic degradation within aerobic manure moving bed biofilm reactors (MBBRs). By examining the removal processes in these reactors, our study aims to elucidate the fate of antibiotics and shed light on the efficiency of degradation mechanisms. The investigation employs advanced analytical techniques of HPLC-HRMS to trace the transformation of antibiotics, providing valuable insights into the potential mitigation of antibiotic residues in manure. The findings contribute to optimizing sustainable manure land application strategies and underscore the significance of aerobic biofilm reactors in addressing environmental concerns related to antibiotic contamination in agricultural ecosystems.He, L.-Y., Ying, G.-G., Liu, Y.-S., Su, H.-C., Chen, J., Liu, S.-S., & Zhao, J.-L.
