The increasing use and associated loss of phosphorus to the environment pose risks to aquatic ecosystems. Technology for phosphorus removal based on microbial aggregates is a natural, ecologically widespread, and sustainable reclamation strategy. Two main processes dominate phosphorus removal by microbial aggregates: extra- and intra-cellular entrapment. Extracellular phosphorus entrapment relies on extracellular polymeric substances, while intracellular entrapment uses a wider variety of phosphorus-entrapping mechanisms. In microbial aggregates, microalgae-bacteria interactions, quorum sensing, and acclimation can enhance phosphorus removal. Based on these insights, we propose novel avenues for entrapping phosphorus using ecological and genetic engineering, manipulated interactions, and integrated processes to create phosphorus removal technology mediated by microbial aggregates.
随着磷的使用量不断增加以及随之向环境中的流失，这对水生生态系统构成了风险。基于微生物聚集体的除磷技术是一种自然的、生态上广泛存在的、可持续的回收策略。微生物聚集体中主要通过两种方式进行除磷：细胞外和细胞内捕获。细胞外磷捕获依赖于细胞外聚合物，而细胞内捕获则使用更广泛的磷捕获机制。在微生物聚集体中，微藻-细菌相互作用、群体感应和驯化可以增强除磷效果。基于这些认识，我们提出了使用生态和遗传工程、操纵相互作用以及整合过程来捕获磷的新途径，从而利用微生物聚集体创造出除磷技术。
