“…Nevertheless, anaerobic digestion provides certain advantages, including production of methane, which offsets energy costs, reduces greenhouse gas emissions, and increases the economic sustainability of farm operations [94]. As summarized in Table 3, removal of various antibiotics during anaerobic digestion has been investigated for swine [43,47,[96][97][98][99] and cattle manure [54,78,95] in 20-216-day experiments. Nearly all analyses were performed at mesophilic temperatures [43,54,78,[95][96][97][98][99], although psychrophilic [47] temperatures have been examined in select studies.…”

Anaerobic sequencing batch reactors, which decouple the solids' residence time and hydraulic retention time and allow for smaller reactor footprints [100], have also been explored for the removal of antibiotics [43,101,102].…”

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.

Background: Spermidine is a biologically active polyamine with extensive application potential in foods and pharmaceuticals. However, previously reported spermidine titers by biosynthesis methods are relatively low, which hinders the industrial fermentation of spermidine. To improve the spermidine titer, key genes affecting the spermidine production were mined to engineer the Bacillus amyloliquefaciens.Results: Genes of S-adenosylmethionine decarboxylase (speD) and spermidine synthase (speE) from different microorganisms were expressed and compared in B. amyloliquefaciens. Therein, the speD from Escherichia coli and speE from Saccharomyces cerevisiae were confirmed to be optimal for spermidine synthesis, respectively. Then, these two genes were co-expressed to generate an engineering strain B. amyloliquefaciens HSAM2(PDspeD-SspeE) with a spermidine titer of 91.31 mg/L, improving by 10.90-fold compared with the control (HSAM2). Through further optimization of fermentation medium, the spermidine titer was increased to 227.35 mg/L, which was the highest titer among present reports. Moreover, the consumption of the substrate S-adenosylmethionine was consistent with the accumulation of spermidine, which contributed to understanding the synthetic pattern of spermidine. Conclusions: Two critical genes for spermidine synthesis were obtained, and an B. amyloliquefaciens cell factory was constructed for enhanced spermidine production, which laid the foundation for further industrial production of spermidine.
