Abstract：
The vast majority of processes in the carbon and nitrogen cycles are driven by microorganisms. The nitrite-dependent anaerobic oxidation of methane (N-DAMO) process links carbon and nitrogen cycles, offering a novel approach for the simultaneous reduction of methane emissions and nitrite pollution. However, there is currently no comprehensive summary of the current status of the N-DAMO process in natural aquatic environments. Therefore, our study aims to fill this knowledge gap by conducting a comprehensive review of the global research trends in N-DAMO processes in various aquatic environments (excluding artificial bioreactors). Our review mainly focused on molecular identification, global study sites, and their interactions with other elemental cycling processes. Furthermore, we performed a data integration analysis to unveil the effects of key environmental factors on the abundance of N-DAMO bacteria and the rate of N-DAMO process. By combining the findings from the literature review and data integration analysis, we proposed future research perspectives on N-DAMO processes in global aquatic environments. Our overarching goal is to advance the understanding of the N-DAMO process and its role in synergistically reducing carbon emissions and removing nitrogen. By doing so, we aim to make a significant contribution to the timely achievement of China\'s carbon peak and carbon neutrality targets.
摘要：
碳和氮循环中的绝大多数过程是由微生物驱动的。依赖亚硝酸盐的甲烷厌氧氧化（N-DAMO）过程连接碳和氮循环，提供了一种同时减少甲烷排放和亚硝酸盐污染的新方法。然而,目前还没有关于自然水生环境中N-DAMO过程的现状的全面总结。因此,我们的研究旨在通过对各种水生环境（不包括人工生物反应器）中N-DAMO工艺的全球研究趋势进行全面审查来填补这一知识空白。我们的综述主要集中在分子鉴定，全球研究网站，以及它们与其他元素循环过程的相互作用。此外，我们进行了数据整合分析，以揭示关键环境因素对N-DAMO细菌丰度和N-DAMO过程速率的影响。通过结合文献综述和数据整合分析的发现，我们对全球水生环境中的N-DAMO过程提出了未来的研究观点。我们的总体目标是加深对N-DAMO工艺及其在协同减少碳排放和去除氮方面的作用的理解。通过这样做,我们的目标是为及时实现中国的碳峰值和碳中和目标做出重大贡献。
