“…TET resistance bacteria counts were included 222 as a control given the lack of tetracycline in the synthetic wastewater. Final concentration 223 for each antibiotic was guided by MIC reports in previous studies: AMP, 16 μg/mL; TET, 224 16 μg/mL; ERY, 50.4 μg/mL; and SMX, 18.1 μg/mL (Pei, et al, 2006, Zheng, et al, 2017. 225…”

The growing practice of wastewater reuse poses a significant risk to further 13 dissemination of antibiotic resistance due to the abundance of antibiotic resistance 14 bacteria (ARB) and antibiotic resistance genes (ARGs) in wastewater effluents. Anaerobic 15 membrane bioreactors (AnMBRs) are an emerging wastewater treatment technology 16 capable of reducing the total ARGs and ARB load discharged to receiving environments 17 compared to conventional aerobic treatment processes. While size exclusion is effective 18 at retaining ARB and its associated intracellular ARGs, the abundance and fate of 19 extracellular ARGs in an AnMBR effluent have not been examined. This study elucidates 20 the effect of combined antibiotics loading (ampicillin, erythromycin, and 21 sulfamethoxazole) on the abundance of intracellular and extracellular ARGs in an AnMBR 22 chemical oxygen demand (sCOD), total chemical oxygen demand (tCOD), volatile fatty 128 acids (VFAs), and mixed liquor and volatile suspended solids (MLSS/MLVSS). Biogas 129 production was monitored by an in-line gas flowmeter and assessed for methane content 130 by gas chromatography with flame ionization detection (GC-FID). Steady AnMBR

This experimental research comparatively investigates the Escherichia coli (E. coli) bacterial inactivation of the TiO 2 photocatalytic thin films fabricated by the sol-gel dip-coating (SG) and low-temperature spray-coating (SP) techniques, with low-intensity (12 μW·cm . Moreover, the essential physical characteristics of the SG-TiO 2 and SP-TiO 2 photocatalytic thin films were determined prior to the experimental bacterial inactivation. The findings showed that both photocatalytic thin films possessed the ideal physical characteristics, especially the SP-TiO 2 thin film. In addition, the viable cell counts, the cell morphology, and the bioluminescence-based adenosine triphosphate (ATP) indicated that both SG-TiO 2 and SP-TiO 2 thin films under UVA could effectively inhibit the proliferation of the E. coli cells in both NB and 0.85% NaCl.

“…can also be a promising solution for reducing the abundance Three disinfection processes -UV, chlorination, and ozonation were evaluated for the treatment of ARGs in secondary effluents from a wastewater treatment plant (Zheng et al, 2017). Results highlighted that ARGs decreased exponentially as the UV dose increased (R 2 = 0.68-0.92).…”

This review su mmarizes selected publications from 2017 highlighting the occurrence of antimicrobial resistance (AMR) genes in the environment with emphasis on the aquatic environment. The review also covers different treatment technologies being developed for AMR genes as an environmental contaminant. The progress made in the area of AMR gene databases and tools is also reviewed. Besides a brief introduction, the content is categorized into three main sections: i) Occurrence of AMR in the Environment, ii) Treatment technologies for AMR, and iii) AMR databases and tools.
