REVIEW OF ANTIBIOTIC DEGRADATION EFFICACY AND EVOLUTION MECHANISM OF ANTIBIOTIC RESISTANCE GENES IN ICPB REACTORS
In recent years,the extensive use of antibiotics has led to increasingly prominent problems of antibiotic contamination and resistance in the environment,posing a serious threat to ecological security.During the degradation of antibiotics,traditional single chemical or biological treatment processes have the disadvantages of high energy consumption and low efficiency,while intimately coupled photocatalysis and biodegradation(ICPB)can achieve efficient degradation and complete mineralization of antibiotics.In this review,the efficiency and influencing factors of antibiotic degradation in ICPB reactors were summarized to review the antibiotic degradation process and microbial community succession characteristics.Furthermore,the assignment characteristics and evolution mechanism of ARGs in ICPB reactors were analyzed.The results showed that the ICPB reactors have been proven to have excellent performance in degrading antibiotics,and the microbial community structure and cell physiological and metabolic functions in the reactors have been undergoing adaptive adjustments,which led to the evolution and flow of ARGs.It is recommended to strengthen the research of ARGs in the ICPB reactors to provide theoretical and technical support for the development of processes for efficient removal of antibiotics and ARGs.
