“…4). This result is in accordance with previous studies showing that mesophilic anaerobic digestion of sewage sludge could result in ARGs reduction even under antibiotic stresses [27,37,41,[50][51][52]. For example, Wang et al [37] found that the ARGs removal efficiency of mesophilic digestion was approximately 50.8%.…”

“…For example, Wang et al [37] found that the ARGs removal efficiency of mesophilic digestion was approximately 50.8%. Zhang et al [52] reported that tetA and tetX were significantly reduced when food waste was used as a substrate in mesophilic anaerobic digestion. It should be noted that short-term batch BMP test was used in this study with the main purpose to evaluate the methanogenic potential of treated residue, while long-term chronic exposure experiments should be performed to better check the induction of ARGs by the raw and thermo-hydrolyzed OTC residues.…”

The presence of high level of antibiotics in the antibiotic fermentation residue is one of the main reasons that prevent their direct disposal or further use as a resource. In this study, the feasibility of using the hydrothermal pretreatment for removing oxytetracycline (OTC) from its fermentation residue and enhancing anaerobic digestion was evaluated under different temperatures i.e. 110, 130, 150 and 170°C. The results showed that the removal rate of OTC increased as a function of temperature, and hydrothermal treatment at 130°C for 5 min was found sufficient to reduce the concentration of OTC from 3.9 mg/g to less than the detection limit (i.e., 0.25 ng/g). Biochemical methane potential tests showed that the cumulative methane production over 23 d was 73.7, 215.9, 656.8, and 439.0NmL CH4/gVS for the raw residue and the residue treated at 130, 150, and 170°C for 5 min, respectively. At the same time, the abundances of tetracycline resistance genes were reduced by hydrothermal treatments followed by anaerobic digestion. Conclusively, it is suggested that hydrothermal treatment at 150°C for 5 min was found beneficial for OTC fermentation residues ensuring the removal of OTC and further use of the residue for anaerobic digestion.

Batik industries have some positive impact on economic growth and socio-cultural development. However, they also produce wastewater in large quantities with high pH, containing biochemical oxygen demand, containing chemical oxygen demand and also have a substance of total suspended solid that do not meet quality standards and also could have negative impacts on the environment. Paoman village, Indramayu regency, is one of the batik small industries supporting economic and socio-cultural development in local communities, although there is an installations system of wastewater treatment plant (WWTP). The study aimed to identify priorities in wastewater management on batik industrial center based on environmental studies, economic studies and social factors in the local community and institutional aspects using analytical hierarchy process. The priorities were identified as follows: (1) application of WWTP systems and technologies for environmental aspect, (2) understanding the perceptions of batik small and medium enterprises (SMEs) for the social aspect, and (3) the cost of installation, operation and maintenance of WWTP for economic aspect.

“…This might lead to a selection and possibly to an increase of ARB in the sludge and in the depurated effluent waters. The effectiveness of activated carbon in reducing antibiotics from wastewater has been extensively proved [10-12], but only a few studies have considered how activated carbon treatments act on ARB and ARGs [1, 20, 21].…”

Background: Conventional wastewater treatment plants discharge significant amounts of antibiotic resistant bacteria and antibiotic resistance genes into natural water bodies contributing to the spread of antibiotic resistance. Some advanced wastewater treatment technologies have been shown to effectively decrease the number of bacteria. Nevertheless, there is still a lack of knowledge about the effectiveness of these treatments on antibiotic resistant bacteria and antibiotic resistant genes. To the best of our knowledge, no specific studies have considered how powdered activated carbon (PAC) treatments can act on antibiotic resistant bacteria, although it is essential to assess the impact of this wastewater treatment on the spread of antibiotic resistant bacteria. </P><P> Methods: To address this gap, we evaluated the fate and the distribution of fluorescent-tagged antibiotic/ antimycotic resistant microorganisms in a laboratory-scale model simulating a process configuration involving powdered activated carbon as advanced wastewater treatment. Furthermore, we studied the possible increase of naturally existing antibiotic resistant bacteria during the treatment implementing PAC recycling. Results: The analysis of fluorescent-tagged microorganisms demonstrated the efficacy of the PAC adsorption treatment in reducing the load of both susceptible and resistant fluorescent microorganisms in the treated water, reaching a removal efficiency of 99.70%. Moreover, PAC recycling did not increase the resistance characteristics of cultivable bacteria neither in the sludge nor in the treated effluent. Conclusion: Results suggest that wastewater PAC treatment is a promising technology not only for the removal of micropollutants but also for its effect in decreasing antibiotic resistant bacteria release.
