摘　　要：古菌作为海洋微生物的重要组分广泛分布于各种海洋环境,在碳、氮、硫等元素的生物地球化学循环和地球生命演化过程中扮演着极为重要的角色。目前古菌主要分为4个超级门(广古菌、TACK古菌、阿斯加德古菌和DPANN古菌),近30个门类。本文综述了广泛分布于近岸或深渊等海洋沉积环境中的四类常见的古菌类群[深古菌门(Bathyarchaeota)、乌斯古菌门(Woesearchaeota)、阿斯加德(Asgard)古菌超门和底栖古菌目(Thermoprofundales,Marine Benthic Group D)]的分布与代谢特征的研究进展,以期为进一步开展这几类古菌方面的研究提供线索和启示。Archaea are important components of marine microorganisms and widely distributed in various marine environments.They play vital roles in the biogeochemical cycles and the evolution of life on Earth.Up to now,archaea include 4 superphyla(Euryarchaeota,TACK,Asgard,and DPANN)and about 30 different phyla.To provide clues and ideas for further research on archaea from coastal or hadal sediments,this review summarizes the recent progresses on the distribution and metabolic features of four common archaeal groups,including Bathyarchaeota,Woesearchaeota,Asgard archaea,and Thermoprofundales(Marine Benthic Group D).
