甲烷作为一种重要的温室气体,其对全球气候变化产生了深远的影响。河流是产甲烷的重要场所,而河流环境的复杂性使得用传统方法难以有效开展对河流微生物产甲烷的深入研究。本文概述了产甲烷微生物的基本分类、在环境中的分布以及甲烷产生的途径,探讨了影响河流微生物产甲烷过程的环境因子,总结了分子生物学技术在河流微生物产甲烷研究中的应用,同时从机理层面对未来河流甲烷排放研究进行了展望,为河流微生物产甲烷的深入研究提供新思路和新方法。

Methane, an important greenhouse gas, has a profound impact on global climate change. Rivers are crucial sites for methane production, and the complexity of river environmental conditions makes it difficult to effectively conduct in-depth research on methane generation by river microorganisms using traditional methods. This article first outlines the basic classification of methanogenic microbes, their distribution and the pathways of methane formation. Then, it explores the environmental factors that affect the methane generation process of microbes. After that, it summarizes the application of molecular biology techniques in the study of river microbial methane production. Finally, it discusses the future research on river methane formation from a mechanistic perspective, providing new ideas and methods for an insight into the exploration on river microbial methane production.
