“…The diversity of antimicrobials detected in US swine manure includes the following: penicillin G, lincomycin, erythromycin, tylosin, bacitracin, sulfadimethoxine, sulfamethazine, sulfamethoxazole, chlortetracycline, oxytetracycline, and trimethoprim [16,[43][44][45][47][48][49]. This diversity is concerning as the complex mixture of antimicrobials in swine manure/lagoons may more readily lead to the development of multidrug-resistant pathogens.…”

“…Metabolites of ampicillin [95], chlortetracycline [78], florfenicol [95], sulfadiazine [97], and tylosin [95] have been reported, reinforcing the contribution of biodegradation processes. Wang et al [45] found a lower reduction in methane production when tylosin A was added directly to manure before anaerobic digestion than when tylosin A was fed to animals, even when the influent tylosin concentrations to the digesters were identical. This difference was attributed to the presence of metabolites in the manure.…”

“…Varel and Hashimoto [108] found that monensin completely inhibited methane production, although they proposed that microbial adaptation could occur. A number of studies reported partial inhibition of biogas production by amoxicillin [107]; ampicillin [105]; chloramphenicol [105]; chlortetracycline [47,99,103,104,108]; danofloxacin [96]; enrofloxacin [103]; florfenicol [95]; micospectone [96], which is a combination of spectinomycin and lincomycin; oxytetracycline [54,99,105,111,113,114]; penicillin [102,105]; sulfamethoxydiazine [98]; tetracycline [98,102,105]; thiamphenicol [107]; and tylosin [45,95,101]. Unsurprisingly, greater inhibitory effects have been identified at higher antibiotic concentrations for several antibiotics: chlortetracycline [99,103,104], enrofloxacin [103], florfenicol [95], oxytetracycline [55,99,111], and tylosin [101].…”

“…The mechanism of antibiotic impacts on anaerobic digestion is convoluted. While the presence of antibiotics can reduce biogas production, substantial evidence exists that antimicrobial compounds (at some concentrations) do not affect process stability as measured by biogas composition [47,54,55,105], pH [45,102,104,113], VFA concentrations [102,113], soluble organic content in the digestion process [54,102], volatile solids removal [43,102], or nitrogen content [45,103]. However, the presence of antibiotics has, under certain conditions, been shown to affect acetate uptake [101,104], pH [47], chemical oxygen demand [47,109], volatile solids removal [47,105], VFA levels [47,105,109], or methane content [104,105].…”

Antibiotic Residues in Animal Waste: Occurrence and Degradation in Conventional Agricultural Waste Management Practices

The presence of antibiotics in animal manure represents a significant concern with respect to the introduction of antibiotic residues to the environment and the development of antibiotic-resistant pathogens. In this review, we have (1) compiled reported detections of antibiotics in poultry litter, swine manure, and cattle manure; and (2) discussed the treatment of antibiotics during conventional agricultural waste management practices. The most reported antibiotics in animal manure were fluoroquinolones, sulfonamides, and tetracyclines, all of which the World Health Organization has listed as critically important for human health. Relatively high treatment efficiencies were observed for antibiotics in composting, anaerobic digestion, and aerobic/anaerobic lagooning. Interestingly, active management of compost piles did not demonstrate a significant increase in antibiotic degradation; however, low-and high-intensity compost systems exhibited high treatment efficiencies for most antibiotics. Anaerobic digestion was not effective for some key antibiotics, including lincosamides and select sulfonamides and fluoroquinolones. Given the potential for energy recovery during anaerobic digestion of agricultural waste, efforts to optimize antibiotic degradation represent an important area for future research. Lagoons also exhibited fairly high levels of antibiotic treatment, especially for aerobic systems; however, the operational costs/complexity of these systems inhibit utilization at the fullscale. No overall trends in antibiotic treatment efficiency during these three agricultural waste management practices were observed. Finally, we posit that increased efforts to include analysis of antibiotic residues in animal manure in national surveillance programs will provide important information to address concerns over the continued use of antimicrobials in animal feeding operations.

“…In recent years, this utilization of AFRs has been forbidden because it could cause serious environmental pollution and induce drug‐resistant bacteria to animals and human beings . AFRs were also used to produce energy through incineration and anaerobic digestion . However, high water content would decrease the efficiency of these processes.…”

Wet antibiotics fermentation residues (AFRs) are rich in water and organic matters. AFRs can cause environmental pollution via secondary fermentation, which also makes them inconvenient to be stored, transported and disposed. A novel dehydration process of wet AFRs was developed by applying inorganic salts as dehydration agent (DA), in which colloidal water in wet AFRs was transferred into the hydrate of DA and formed solid AFRs–DA mixture at room temperature. When Na2SO4 was used as the optimal DA, differential thermal gravity (DTG) analysis demonstrated that the temperature of complete dewatering of AFRs–DA mixture decreased from 162.7 to 98.5°C compared with wet AFRs, and the dewatering energy consumption decreased by 26.58%. The suitable mass ratio of Na2SO4 and AFRs was in the range of 1.2–2.0. During the process of incineration at 750°C, the organic matters in the AFRs–DA mixture were completely converted into small molecules, for example, H2O and CO2, and the harmless disposal of AFRs was realized. Meanwhile, DA changed from hydrate to anhydrous form, from which DA can be recycled. The dewatering reaction time decreased by 61.8% with the recycled Na2SO4 at least five recycles. This study provides a promising energy saving approach for wet AFRs disposal. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1901–1907, 2018
