Abstract:

The widespread use of antibiotics, coupled with the inadequate removal efficiency of these substances by traditional wastewater treatment methods, has resulted in the global presence of antibiotics at varying concentrations in aquatic ecosystems. The microalgae-bacteria consortia presents a sustainable approach to wastewater treatment,characterized by its high removal capacity, suppression of resistance gene proliferation, and the potential for biomass recovery. This paper provided a comprehensive review of the structure and characteristics of the microalgae-bacteria consortia, while also summarized the effects of antibiotics on this system. The mechanisms of antibiotic removal by microalgae and bacteria were analyzed, and the potential pathways for antibiotic degradation within the symbiotic framework were presented. Furthermore, this paper critically examined the influence of various factors,including the type and concentration of antibiotics, the biochemical composition of the microalgae-bacteria consortia,illumination, temperature, as well as pH on the efficiency and pathways of antibiotic removal. Additionally, innovative microalgae-bacteria consortia currently in development for the purpose of antibiotic remediation was highlighted. Based on the findings, future research directions were proposed, which included investigating the molecular interactions between microalgae and bacteria, optimizing species combinations, and assessing the impact of antibiotics on the microalgae-bacteria consortia within complex aquatic environments.

Key words: microalgae-bacteria consortia, antibiotics, removal pathways, influencing factors

摘要:

抗生素的广泛使用及传统污水处理手段对抗生素的去除效率偏低导致全球范围内的水环境中均有不同浓度的抗生素检出。藻菌共生系统是一种可持续的废水处理方法,具有高效去除抗生素、减少抗性基因增殖和收获生物质等优势。综述了藻菌共生系统的结构及特性,总结了抗生素对藻菌共生系统的影响;综合微藻与细菌对抗生素的去除机制,归纳出藻菌共生系统去除抗生素的可能途径;分析讨论了抗生素种类及浓度、生物组成、光照、温度、pH等因素对抗生素去除途径及效率的影响;介绍了现有的基于藻菌共生系统去除抗生素的新技术。在此基础上,提出了未来需要深入研究的方向,如藻菌分子层面上的相互作用、物种的合理组合及复杂水环境中抗生素对藻菌共生系统的影响等。
