Insight into effect of high-level cephalexin on fate and driver mechanism of antibiotics resistance genes in antibiotic wastewater treatment system

A Review of Current Bacterial Resistance to Antibiotics in Food Animals

“…Except for the above, other methods (such as photocatalyst, biochar composting, nanotechnology, reactors, etc.) used in diverse environmental samples can be potentially applied for the degradation of antibiotics and ARGs in animal farms due to excellent stability and recyclability ( Tables 2 , 3 ; Chen et al, 2018 ; Peng et al, 2018 ; Shi et al, 2018 ; Srinivasa Raghavan et al, 2018 ; Guo et al, 2020 ; Hu et al, 2020 ; Meng et al, 2020 , 2021 ; Huang B. et al, 2021 ; Li S. et al, 2021 ; Wang J. et al, 2021 ; Zhou et al, 2021 ).…”

Treatment of antibiotic cephalexin by heterogeneous electrochemical Fenton-based processes using chalcopyrite as sustainable catalyst

“…to its low metabolic degradation rate and its ability to induce the proliferation of antibiotic-resistant bacteria (Roth et al, 2019;Meng et al, 2020). It has been found in wastewater treatment plants and waterways around the world (Baquero et al, 2008;Ledezma Estrada et al, 2012).…”

Electron shuttles enhanced the removal of antibiotics and antibiotic resistance genes in anaerobic systems: A review

“…However, conventional WWTPs were not specifically designed for the removal of antibiotics ( Chen Y. et al, 2020 ) and antibiotics entering the biological units of WWTPs often change the microbial community structure, affect the stability of the biological treatment units and reduce the treatment efficiency and even cause the collapse of the biological treatment systems ( Meng et al, 2017a , b ; Zhang Z. H. et al, 2018 ). In addition, the selective pressure of the WWTPs also promotes horizontal genes transfer (HGT) and vertical genes transfer (VGT), which further diffuse ARGs into the environment ( Jia et al, 2017 ; Chen Y. et al, 2020 ; Meng et al, 2020 ). A study of antibiotics and ARGs abundance in a WWTP and its upstream and downstream reaches in Nanjing, China, found that the level of antibiotics in the effluent of the treatment plant was reduced by 90% compared to the raw water and the number of detected antibiotics was reduced from 10 to 5.…”
