摘要

厌氧氨氧化（anammox）性能的稳定性与微生物相互作用的动态平衡密不可分。然而，人们对厌氧氨氧化系统中关键微生物的了解仍然有限。本研究通过对 186 个 16S rRNA 数据集的分析，结合各种生态分析方法，确定了anammox 过程中的关键微生物。库恩尼菌（Candidatus_Kuenenia）与其他关键微生物之间的相互作用最为显著，对不同水质的耐受性更高，而杰特尼菌（Candidatus_Jettenia）的栖息地特异性更高。在不利条件下，厌氧菌可以通过加强与某些微生物的相互作用来减少不利环境的影响。本研究全面回顾了anammox系统中关键微生物的主要功能及其相互作用，并总结了几种常见的相互作用机制，为理解anammox过程的启动和稳定运行提供了新的见解。

Deciphering key microbes and their interactions within anaerobic ammonia oxidation systems

The stability of anaerobic ammonium oxidation (anammox) performance is inseparably linked to the dynamic equilibrium of microbial interactions. However, understanding of the key microbes within anammox systems remains limited. Through the analysis of 186 16S rRNA datasets combined with various ecological analysis methods, this study identified key microbes in the anammox process. Interactions between Candidatus_Kuenenia and other key microbes are the most significant with greater tolerance to differing water quality, while Candidatus_Jettenia have higher habitat specificity. Under adverse conditions, anammox bacteria can reduce the impact of unfavorable environments by enhancing interactions with certain microbes. This study comprehensively reviews the main functions of key microbes in the anammox system and their interactions, and summarizes several common interaction mechanisms, providing new insights for understanding the startup and stable operation of the anammox process.
