Abstract：
Microalgae growth-promoting bacteria (MGPB), both actinobacteria and non-actinobacteria, have received considerable attention recently because of their potential to develop microalgae-bacteria co-culture strategies for improved efficiency and sustainability of the water-energy-environment nexus. Owing to their diverse metabolic pathways and ability to adapt to diverse conditions, microalgal-MGPB co-cultures could be promising biological systems under uncertain environmental and nutrient conditions. This review proposes the recent updates and progress on MGPB for microalgae cultivation through co-culture strategies. Firstly, potential MGPB strains for microalgae cultivation are introduced. Following, microalgal-MGPB interaction mechanisms and applications of their co-cultures for biomass production and wastewater treatment are reviewed. Moreover, state-of-the-art studies on synthetic biology and metabolic network analysis, along with the challenges and prospects of opting these approaches for microalgal-MGPB co-cultures are presented. It is anticipated that these strategies may significantly improve the sustainability of microalgal-MGPB co-cultures for wastewater treatment, biomass valorization, and bioproducts synthesis in a circular bioeconomy paradigm.
摘要：
微藻生长促进细菌（MGPB），放线菌和非放线菌，最近受到了相当多的关注，因为它们有潜力开发微藻-细菌共培养策略，以提高水-能源-环境关系的效率和可持续性。由于其不同的代谢途径和适应不同条件的能力，在不确定的环境和营养条件下，微藻-MGPB共培养可能是有前途的生物系统。本文综述了MGPB通过共培养策略用于微藻培养的最新进展和进展。首先,介绍了用于微藻培养的潜在MGPB菌株。Follows,综述了微藻-MGPB的相互作用机制及其共培养物在生物质生产和废水处理中的应用。此外，合成生物学和代谢网络分析的最新研究，提出了选择这些方法进行微藻-MGPB共培养的挑战和前景。预计这些策略可以显着提高微藻-MGPB共培养物用于废水处理的可持续性，生物量增值，和循环生物经济范式中的生物产品合成。
