污水处理系统中藻/菌与藻-菌共生体胞外多糖研究进展
- Title:
- Research Progress of Extracellular Polysaccharide of Microalgae/Bacteria and Microalgal-Bacterial Symbiosis in Wastewater Treatment System
- 摘要:
- 当前，藻-菌共生系统因其减污降碳特质受到广泛关注。胞外多糖在维持生物系统稳定性方面具有重要作用，但其特性缺乏系统论述。对污水处理系统中微藻/细菌胞外多糖的提取与纯化方法进行了综述，归纳了适合藻-菌共生体胞外多糖的提取纯化方法。对微藻/细菌胞外多糖的组成/结构进行了系统分析，并对未来研究方向进行了展望。藻-菌共生体胞外多糖的组成与结构取决于藻-菌质量比及其类群，其提取方法、精细结构、合成途径等有待进一步研究。此项工作可加深对藻/菌及藻-菌共生体胞外多糖的认识，为污水生物处理及资源化应用提供理论基础。
- Abstract:
- Microalgal-bacterial symbiosis systems have garnered significant attention for their potential to reduce pollution and carbon emissions. Extracellular polysaccharides play a significant role in maintaining the stability of biological systems, but their characteristics remain insufficiently explored. This review comprehensively examines the extraction and purification methods of extracellular polysaccharides from microalgae/bacteria in wastewater treatment systems and summarizes an optimized approach for microalgal-bacterial symbiosis. The composition and structure of extracelluar polyscaccharides from microalgae/bacteria are systematically analyzed, and the future research directions were envisioned. The composion and structure of the extracellular polysaccharides of the microalgal-bacterial symbiosis depend on the mass ratio of microalgae to bacteria, taxa. Additionally, the need for further investigation into the extraction methods, fine structure, biosynthetic pathways is emphasized. This work aims to advance the understanding of extracellular polysaccharides in microalgae/bacteria and microalgal-bacterial symbiosis systems, providing the theoretical basis for the integration of biological wastewater treatment and resource recovery.
