“…Upon successful removal of the antibiotics, the antibiotic fermentation residue can be utilized as carbon-rich biomass [5]. Although, Fenton process, ozonation, and other advanced oxidation processes are found effective for the reduction of OTC [6,7], they have certain shortcomings including high chemical oxygen demand (COD) and high level of suspended solids in the residue [8]. Since antibiotics are prone to hydrolysis at elevated temperatures, hydrothermal treatment may be a suitable alternative technology for their successful removal from the residue [9].…”

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.

“…For example, Qi et al applied microelectrolysis combined with sequencing batch reactor process to treat oxytetracycline production wastewater. When the influent chemical oxygen demand (COD) was 500 mg/L, the average COD removal rate increased from 76.1% to 94.4% (Qi et al, 2016). Microelectrolysis combined with expanded granular sludge bed and anaerobic/oxic system was used to treat oxytetracycline production wastewater.…”

The application of iron–carbon microbial cell activated sludge (ICMC-AS) was carried out in a membrane bioreactor (MBR) processor to treat wastewater from an integrated railway station. Results showed that the chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) removal efficiencies of the original MBR processor increased from 80%, 30%, and 10% to 92%, 93.5%, and 92%, respectively. Further research showed that the combined sewage treatment system also had a strong impact resistance ability. The combined sewage treatment system ran stably when the COD, TN, and TP concentrations changed greatly. The in-depth analysis of the reaction process and reaction rate of the combined sewage treatment system revealed that the combined system is dominated by COD removal with high nitrogen removal efficiency. The removal rate constants of various pollutants were in the order: KCOD (0.647 ± 0.017) > KNO3−−N (0.416 ± 0.044) > KNH4+−N (0.275 ± 0.014) > KTN (0.258 ± 0.083). Calculations of the energy saving and carbon emission reduction of the combined system showed that the system’s annual carbon emission reduction could reach more than 388,203.55 kg CO2e, which remarkably improves the carbon emission reduction effect and obtains a good green effect. The results indicate that adding ICMC-AS to the MBR processor for combined wastewater treatment can substantially improve the efficiency of wastewater treatment and obtain better energy-saving and emission-reducing effects. This combined application provides an effective way for the transformation and upgrading of small- and medium-scale water treatment systems.

“…Because of its effective antimicrobial properties, good therapeutic effect, and relative inexpensiveness, OTC has become one of the most commonly used TCs in animal husbandry, aquaculture, and fruit crop production [ 3 , 4 ]. On the other hand, an exclusive drive for economic benefits results in OTC over-use, such that OTC residue in food products, such as meat, milk, eggs, honey, and fruits happens all the time [ 5 , 6 , 7 ]. Such residues might be transferred into the human body and result in liver damage, ototoxicity, nephrotoxicity, allergic reactions, and yellowish discoloration of teeth [ 8 , 9 ].…”

Driven by economic interests, the abuse of antibiotics has become a significant concern for humans worldwide. As one of the most commonly used antibiotics, oxytetracycline (OTC) residue in animal-derived foods occurs occasionally, which has caused danger to humanity. However, there is still no simple and efficient solution to detect OTC residue. Here, an easily-operated colorimetric strategy for OTC detection was developed based on nickel ions (Ni2+) immobilized carboxymethylcellulose/polyacrylonitrile nanofibrous membranes (Ni@CMC/PAN NFMs). Owing to numerous O- and N-containing groups OTC has a strong tendency to complex with Ni2+ on the strips, inducing a color change from light green to yellow visible to the naked eye. The NFMs structural features, CMC functionalization process, and Ni2+ immobilization amount was carefully regulated to assure OTC detection whilst maintaining the inherent characteristics of NFMs. With the benefits of the large specific surface area (SSA) and small pore size of NFMs, the strips not only exhibited a rapid response (2 min), and low detection limit (5 nM) but also performed with good reversibility and selectivity concerning OTC detection over other antibiotics. The successful development of such enchanting nanofibrous materials may provide a new comprehension into the design and improvement of colorimetric strips.
