“…In contrast, the removal and biodegradability of SMX in anaerobic systems has not been widely studied. There are few studies regarding the anaerobic biodegradability characteristics of SMX in the literature (Gartiser et al, 2007;Cetecioglu, et al, 2013;Aydin et al, 2015;Martín et al, 2015). Gartiser et al (2007) assessed the biodegradability of the selected antibiotics.…”

“…The authors found an SMX removal of 70% under methanogenic conditions. Aydin et al (2015) showed the removal behavior of SMX with other antibiotic combinations, but SMX and other antibiotics were measured in only the liquid phase, and the sorption efficiency was not studied. In another study, the occurrence of pharmaceuticals, including SMX, was assessed in sludge stabilization treatment, and it was shown that anaerobic sludge stabilization is the most effective method for the degradation of these compounds (Martín et al, 2015).…”

“…It has been shown, for example, that antibiotic concentrations of above 1 mg/L in anaerobic digestion systems can break down acetate, butyrate and propionate degradation pathways and lead to an accumulation of volatile fatty acids (VFAs) in digesters [60,67]. Furthermore, a similar study by Aydin et al found that concentrations of combined sulfamethoxazole, tetracycline and erythromycin antibiotic mixtures of above 10 mg/L also inhibited chemical oxygen demand (COD) removal and biogas generation rates [68]. A different study of the same anaerobic digesters used quantitative PCR to quantify formate-tetrahydrofolate ligase (FTHFS), acetyl-coenzyme A synthetase (ACAS), and methyl coenzyme M reductase (mcrA) genes and reveal that this antibiotic mixture inhibited reactor performance by disrupting acetogenesis, acetoclastic methanogenesis, and hydrogenotrophic methanogenesis pathways, respectively [69].…”

Broad and increasing interest in sustainable wastewater treatment has led a paradigm shift towards more efficient means of treatment system operation. A key aspect of improving overall sustainability is the potential for direct wastewater effluent reuse. Anaerobic membrane bioreactors (AnMBRs) have been identified as an attractive option for producing high quality and nutrient-rich effluents during the treatment of municipal wastewaters. The introduction of direct effluent reuse does, however, raise several safety concerns related to its application. Among those concerns are the microbial threats associated with pathogenic bacteria as well as the emerging issues associated with antibiotic-resistant bacteria and the potential for proliferation of antibiotic resistance genes. Although there is substantial research evaluating these topics from the perspectives of anaerobic digestion and membrane bioreactors separately, little is known regarding how AnMBR systems can contribute to pathogen and antibiotic resistance removal and propagation in wastewater effluents. The aim of this review is to provide a current assessment of existing literature on anaerobic and membrane-based treatment systems as they relate to these microbial safety issues and utilize this assessment to identify areas of potential future research to evaluate the suitability of AnMBRs for direct effluent reuse.

“…Quite different removal rate of TC either in WWTPs2730 or Lab-scale experiments have been reported25313839. For instance, a TC removal rate of 67.9–100% was reported by Karthikeyan and Meyer40 after secondary wastewater treatment in a WWTP.…”

“…measured the removal rate of TC as 40–90% in different phases in a anaerobic sequencing batch reactor before metabolic activities practically declined and nearly ceased. Aydin et al 39. found that TC removal efficiency ranged from 60–95%, and this rate was lower than 3% when the COD removal efficiency and biogas production significantly decline after dosing with an antibiotic mixture (containing TC).…”

The effect of tetracycline (TC) antibiotic on biogas generation in anaerobic wastewater treatment was studied. A lab-scale Anaerobic Baffled Reactor (ABR) with three compartments was used. The reactor was operated with synthetic wastewater in the absence of TC and in the presence of 250 μg/L TC for 90 days, respectively. The removal rate of TC, volatile fatty acids (VFAs), biogas compositions (hydrogen (H2), methane (CH4), carbon dioxide (CO2)), and total biogas production in each compartment were monitored in the two operational conditions. Results showed that the removal rate of TC was 14.97–67.97% in the reactor. The presence of TC had a large negative effect on CH4 and CO2 generation, but appeared to have a positive effect on H2 production and VFAs accumulation. This response indicated that the methanogenesis process was sensitive to TC presence, but the acidogenesis process was insensitive. This suggested that the presence of TC had less influence on the degradation of organic matter but had a strong influence on biogas generation. Additionally, the decrease of CH4 and CO2 generation and the increase of H2 and VFAs accumulation suggest a promising strategy to help alleviate global warming and improve resource recovery in an environmentally friendly approach.
