Abstract

Algae-bacteria consortia treatment has been found to be a promising method for the remediation of aqueous systems. Given the scope of previous reviews on algae-bacteria interactions, the sections on chemical signaling between algae and bacteria don’t cover the current knowledge gap, and recent advances of algae-bacteria consortia in aqueous remediation don’t explore the full depth. Accordingly, the specific aim of this review was to thoroughly screen and summarize recent peer-reviewed literature on (1) the mechanism of algal selection and enrichment in wastewater treatment; (2) interactions between algae and bacteria in ecological niche environments; (3) chemical signaling between algae and bacteria; (4) aqueous remediation using the algae-bacteria consortia; and (5) advanced treatment techniques combined with algae-bacteria systems for improved aqueous remediation. The main current challenges and future perspectives in algae-bacteria consortia wastewater treatment are proposed, including: (i) comprehensively establishing the network of interactions between algae and bacteria, especially quorum sensing and phycospheric interactions; (ii) developing a detailed understanding of the chemical exchange between microbial species based on molecular diffusion processes; (iii) tracking complex algae-bacteria interactions in aquatic environments using machine learning (ML), providing a potential tool for the design of beneficial and customizable synthetic microbial communities for wastewater treatment; (iv) integrating advanced treatment techniques (e.g., MBRs, UV photolysis and biological activated carbon) with algae-bacteria consortia systems, increasing the sustainability and applicability of treatment processes. Therefore, this review provides guidance and insights on the future development of algae-bacteria consortia treatment systems and their potential application for aqueous remediation.

摘要

已经发现藻类-细菌联合体处理是修复水系统的有前景的方法。鉴于先前关于藻类-细菌相互作用的评论范围，关于藻类和细菌之间的化学信号传导的部分并未涵盖当前的知识空白，并且藻类-细菌联合体在水体修复中的最新进展并未探索全部深度。因此，本综述的具体目的是彻底筛选和总结近期同行评议的文献：（1）废水处理中藻类选择和富集的机制；(2) 生态位环境中藻类与细菌的相互作用；(3) 藻类和细菌之间的化学信号传导；(4) 使用藻-细菌联合体进行水修复；(5) 先进的处理技术与藻细菌系统相结合，以改进水体修复。提出了藻-菌联合体废水处理当前面临的主要挑战和未来展望，包括：（i）全面建立藻类和细菌相互作用网络，特别是群体感应和藻类相互作用网络；(ii) 详细了解基于分子扩散过程的微生物物种之间的化学交换；(iii) 使用机器学习 (ML) 跟踪水生环境中复杂的藻类-细菌相互作用，为设计用于废水处理的有益和可定制的合成微生物群落提供潜在工具；(iv) 整合先进的处理技术（例如 MBR，紫外光解和生物活性炭）与藻类-细菌联合系统，提高了处理过程的可持续性和适用性。因此，本综述为藻类-细菌联合处理系统的未来发展及其在水体修复中的潜在应用提供了指导和见解。
