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.
在未来循环经济的背景下，将废物回收转化为新材料和能源正成为一项重大挑战，这需要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水污泥转化为生物甲烷、肥料和其他产品，然而微生物消化的效率受到污泥中抗生素的限制，这些抗生素源自用于人类和动物健康的药物消费。在此，我们展示了中国废水中的抗生素水平，然后回顾了抗生素对水解、产酸和产甲烷的影响，重点关注大环内酯类、四环素类、β-内酰胺类和抗生素混合物。我们详细阐述了抗生素对发酵细菌和产甲烷古菌的影响。大多数结果显示抗生素对厌氧消化有不利影响，但也有一些抗生素促进水解、产酸和产甲烷。
