Purpose of Review

Microbial interaction determines the performance, stability, and resilience of the microbial communities. Understanding microbial interactions benefits the development of environmental biotechnology. The purpose of this review is to summarize the recent findings of microbial interactions in pollution control ecosystems from aspects of the substrate degradation, energy utilization, electron transfer, and information exchange.

Recent Findings

Cross-feeding of substrates such as vitamins was found to be necessary for the degradation of some trace organic contaminants. Under different conditions, microorganisms can mediate various energy-utilization pathways (e.g., co-metabolism) to grow. Electroactive bacteria and cable bacteria can mediate extracellular electron transfer via conductive pili, c-type cytochrome, or filamentous structure. Quorum sensing plays an important role in the microbial aggregation and functional microbe enrichments. With all these knowledges, it will potentially benefit the development of disruptive environmental biotechnologies.

Summary

This review summarized recent findings of microbial interactions, many of which have huge potentials to advance environmental biotechnologies. Multi-omics methods should be further applied for comprehensively confirming known and unknown microbial processes. The co-occurrence network should be applied to unravel the interlinks among substrate degradation, energy utilization, electron transfer, and information exchange. The proper regulation of microbial interactions in practical application should be further addressed.

污染控制生态系统中的微生物相互作用

审查目的

微生物相互作用决定了微生物群落的性能，稳定性和弹性。了解微生物的相互作用有益于环境生物技术的发展。这篇综述的目的是从基质降解，能量利用，电子转移和信息交换等方面总结污染控制生态系统中微生物相互作用的最新发现。

最近的发现

发现基质（如维生素）的交叉进料对于降解某些痕量有机污染物是必需的。在不同条件下，微生物可以介导各种能量利用途径（例如，共代谢）生长。电活性细菌和电缆细菌可以通过导电菌毛，c型细胞色素或丝状结构介导细胞外电子转移。群体感应在微生物聚集和功能性微生物富集中起着重要作用。有了所有这些知识，它将潜在地有益于破坏性环境生物技术的发展。

概括

这篇综述总结了微生物相互作用的最新发现，其中许多具有推动环境生物技术发展的巨大潜力。多组学方法应进一步应用于全面确认已知和未知的微生物过程。应同时使用共现网络，以揭示底物降解，能量利用，电子转移和信息交换之间的相互联系。实际应用中微生物相互作用的适当调节应进一步解决。
