佛斯特拉古菌门(Verstraetearchaeota)研究进展

Research progress of the archaeal phylum Verstraetearchaeota

产甲烷古菌广泛分布在缺氧环境中,是有机质厌氧降解产甲烷过程中的关键功能微生物。它们在全球碳元素循环、气候变化等方面发挥着十分重要的作用。传统观念认为产甲烷古菌仅分布在广古菌门(Euryarchaeota)中,最新研究发现一系列新的非广古菌门(non-Euryarchaeota)产甲烷古菌,推测其不仅具有产甲烷能力,可能还具有发酵复杂有机物的代谢潜力。本文围绕佛斯特拉古菌门(Verstraetearchaeota)产甲烷古菌,系统阐述了它的系统分类、碳代谢机制和生态学分布等方面的研究进展,并展望了未来发展趋势。

Methanogenic archaea are widely distributed in anoxic environments and are the key functional microorganisms in the process of anaerobic degradation of organic matter.They play a very important role in the global carbon cycle and climate change.Traditionally,methanogenic archaea are believed to only distribute in the phylum of Euryarchaeota,however,a series of non-Euryarchaeota methanogenic archaea have been found in the latest researches.It is speculated that the new archaea not only have methanogenic ability,but also have the metabolic ability of fermenting complex organic matter.This review focuses on methanogens of the archaeal phylum Verstraetearchaeota,summarizes research progresses of its systematic taxonomy,carbon metabolism and ecological distributions,and anticipates the trends of future research directions.
