Abstract EN
Archaea plays an important role in the global geobiochemical circulation of various environments.
However, much less is known about the ecological role of archaea in freshwater lake sediments.
Thus, investigating the structure and diversity of archaea community is vital to understand the metabolic processes in freshwater lake ecosystems.
In this study, sediment physicochemical properties were combined with the results from 16S rRNA clone library-sequencing to examine the sediment archaea diversity and the environmental factors driving the sediment archaea community structures.
Seven sites were chosen from Poyang Lake, including two sites from the main lake body and five sites from the inflow river estuaries.
Our results revealed high diverse archaea community in the sediment of Poyang Lake, including Bathyarchaeota (45.5%), Euryarchaeota (43.1%), Woesearchaeota (3.6%), Pacearchaeota (1.7%), Thaumarchaeota (1.4%), suspended Lokiarchaeota (0.7%), Aigarchaeota (0.2%), and Unclassified Archaea (3.8%).
The archaea community compositions differed among sites, and sediment property had considerable influence on archaea community structures and distribution, especially total organic carbon (TOC) and metal lead (Pb) (p<0.05).
This study provides primary profile of sediment archaea distribution in freshwater lakes and helps to deepen our understanding of lake sediment microbes.
