在未来循环经济的背景下,将废物回收利用成为新材料和新能源的重大挑战,呼吁先进的废物处理方法。例如,微生物介导的厌氧消化被广泛用于将污泥转化为生物甲烷,化肥和其他产品,然而,微生物消化的效率受限于污泥中抗生素的存在,源自人类和动物健康的药物消费。这里我们介绍了中国废水中的抗生素含量,然后我们回顾了抗生素对水解的影响,产酸和产甲烷,专注于大环内酯类,四环素,β-内酰胺和抗生素混合物。我们详细介绍了抗生素对发酵细菌和产甲烷菌的影响。大多数结果显示抗生素对厌氧消化的不利影响,然而一些抗生素促进水解,产酸和产甲烷。
Recycling waste into new materials and energy is becoming a major challenge in the context of the future circular economy, calling for advanced methods of waste treatment. For instance, microbially-mediated anaerobic digestion is widely used for conversion of sewage sludge into biomethane, fertilizers and other products, yet the efficiency of microbial digestion is limited by the occurrence of antibiotics in sludges, originating from drug consumption for human and animal health. Here we present antibiotic levels in Chinese wastewater, then we
review the effects of antibiotics on hydrolysis, acidogenesis and methanogenesis, with focus on macrolides, tetracyclines, β-lactams and antibiotic mixtures. We detail effects of antibiotics on fermentative bacteria and methanogenic archaea. Most results display adverse effects of antibiotics on anaerobic digestion, yet some antibiotics promote hydrolysis, acidogenesis and methanogenesis.
