Anaerobic digestion is one of the best ways to re-use animal manure and agricultural residues, through the production of combustible biogas and digestate. However, the use of antibiotics for preventing and treating animal diseases and, consequently, their residual concentrations in manure, could introduce them into anaerobic digesters. If the digestate is applied as a soil fertilizer, antibiotic residues and/or their corresponding antibiotic resistance genes (ARGs) could reach soil ecosystems. This work investigated three common soil emerging contaminants, i.e., sulfamethoxazole (SMX), ciprofloxacin (CIP), enrofloxacin (ENR), their ARGs sul1, sul2, qnrS, qepA, aac-(6′)-Ib-cr and the mobile genetic element intI1, for one year in a full scale anaerobic plant. Six samplings were performed in line with the 45-day hydraulic retention time (HRT) of the anaerobic plant, by collecting input and output samples. The overall results show both antibiotics and ARGs decreased during the anaerobic digestion process. In particular, SMX was degraded by up to 100%, ENR up to 84% and CIP up to 92%, depending on the sampling time. In a similar way, all ARGs declined significantly (up to 80%) in the digestate samples. This work shows how anaerobic digestion can be a promising practice for lowering antibiotic residues and ARGs in soil.

Overuse and misuse of different antibiotics are considered as one of the main causes of antibiotics accumulation in the environment, most commonly used antibiotics are semimetabolized and excreted by humans to the environment. Studies reported that antibiotic usage exceeds 100,000 tons per year, and this amount may be shocking. However, in fact, the persistence of antibiotic compounds may be more dangerous than the used amount, so it is necessary to develop new methods for elimination of these new pollutants from the environment, especially from water. In this paper, we highlight new and more efficient methods used for removing antibiotic residues (AR) and antibiotic resistance genes (ARGs). The new techniques are Fe3O4/red mud nanoparticles, 3D hierarchical porous-structured biochar aerogels, calcined layered double hydroxides, co-doped UiO-66 nanoparticles, Cu@TiO2 hybrids, bioelectrochemical systems, and aerobic granulation process. Most of these methods showed good performance in removing AR and ARGs that ranged from 85% to 95%. These percentages are consider very efficient compared with traditional wastewater treatment methods.

AbstractSlaughterhouse wastewater is considered a reservoir for antibiotic-resistant bacteria and antibiotic residues, which are not sufficiently removed by conventional treatment processes. This study focuses on the occurrence of ESKAPE bacteria (Enterococcus spp., S. aureus, K. pneumoniae, A. baumannii, P. aeruginosa, Enterobacter spp.), ESBL (extended-spectrum β-lactamase)-producing E. coli, antibiotic resistance genes (ARGs) and antibiotic residues in wastewater from a poultry slaughterhouse. The efficacy of conventional and advanced treatments (i.e., ozonation) of the in-house wastewater treatment plant regarding their removal was also evaluated. Target culturable bacteria were detected only in the influent and effluent after conventional treatment. High abundances of genes (e.g., blaTEM, blaCTX-M-15, blaCTX-M-32, blaOXA-48, blaCMY and mcr-1) of up to 1.48 × 106 copies/100 mL were detected in raw influent. All of them were already significantly reduced by 1–4.2 log units after conventional treatment. Following ozonation, mcr-1 and blaCTX-M-32 were further reduced below the limit of detection. Antibiotic residues were detected in 55.6% (n = 10/18) of the wastewater samples. Despite the significant reduction through conventional and advanced treatments, effluents still exhibited high concentrations of some ARGs (e.g., sul1, ermB and blaOXA-48), ranging from 1.75 × 102 to 3.44 × 103 copies/100 mL. Thus, a combination of oxidative, adsorptive and membrane-based technologies should be considered.
