Some previously described groups were included, such as MCG group 5b, group 8, group 4, group 11, group 5a, and group 15 Figure 3.
P were similar among sites Table 1. Although the water area of Poyang Lake is very huge, two parts could be divided depending on the hydrographic conditions. IdI IAI ls. National Center for Hgi InformationU.

Based on the heatmap analysis of archaea community on order level affiliation, all sampling sites could be divided into three groups: However, subject to the poor culturability and limited isolates of archaea members, the taxonomy was obscured in many previous studies. Seven sampling sites were selected for study Figure 1: However, both dominance and evenness showed diverse and stable structures of archaea community from sediment samples.
Thus, the abundance of Methanosarcina, Methanobacteriales, and Methanomicrobiales in this study may suggest that their growth substrate was not limited, and the elevation of organic carbon from eutrophication or terrestrial organic carbon influx may change methanogen abundance as well as CH 4 production rates [ 48 ].
About this image Short Description: Composition of bacterial and archaeal communities in freshwater sediments with different contamination levels Lake Geneva, Switzerland Water Research. For sites NP and SP from the central lake, the most abundant archaea both belonged to Methanosarcinales Click here to view. N c -” Heterotrophic Archaea dominate sedimentary subsurface ecosystems off Peru.
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.
Studies on methanogenic consortia associated with mangrove sediments of ennore. The ACE values of archaea community showed remarkable negative correlations to the ratio of C: Allen County Public Library. Sediment samples were timely freeze-dried to detect geochemical characteristics. Chinese Journal of Geochemistry.

Identification of key vgi in the energy metabolism of the hyperthermophilic sulfate-reducing archaeon Archaeoglobus fulgidus by transcriptome analyses. Influential Factors on Archaea Communities Pearson’s correlation coefficients were used to investigate the correlations between the lake sediment properties and the archaea communities Table 4.
MCG-1, Methanomicrobiales, and Methanosarcinales all have a wide habitat in various big environments. Journal of Hazardous Materials. The most similar sequences were extracted from the GeneBank database. Distribution of Archaea Community The sediment archaea community showed diverse distribution patterns among seven sampling sites.
The inflow river has 7751-1 an important contribution to the eutrophication and contamination of Poyang Lake; among the five tributaries, Gan, Xin, and Rao Rivers were polluted by industrial plants discharges copper and phosphate mines in the upstream of Rao and Xin Rivers and urban wastes Nanchang City in the upstream of Gan River [ 20 ]. Biodiversity changes in the lakes of the Central Yangtze.
See our other membership options. The salinity played an important role in controlling diversity and distribution of archaea in estuarine sediments [ 1415 ], particle sizes and 7511-1 O 2 saturation also shaped the sediment archaea distribution [ 16 ]. The coordinates and water depth of these selected sampling sites are shown in Table 1.
W ft pSI’ Consequently, the investigating of sediment archaea community is vital to understand the metabolic processes in freshwater lake ecosystems [ 8 ]. The dominance of Methanomicrobiales and Methanosarcinales in sedimental archaea community of this study was not a single event, and similar results have also been reported in other freshwater lakes, such as Lake Biwa [ 41 ], Lake Soyang [ 42 ], and Lake Dagow [ 43 ].
Allen County Public Library State: The sediment microbial community is often affected by sediment properties, and the community composition is structured by both nutrient availability and environmental pressures from sediment. Our study revealed spatial heterogeneity of archaea community in the sediment of Poyang Lake. However, much less is known about the ecological role bgl archaea in freshwater lake sediments.

Applied and Environmental Microbiology. Water depth may influence the precipitation process of sediment and affected many sediment parameters [ 3453 ], while the pressure of Pb selected special archaea groups and reduced the evenness.
Supplementary Material Supplementary file showed the detailed phylogenetic tree of all sequences found in this study. The main composition of the whole archaeal community was also shown in the pie chart. The Journal of Microbiology. The seven phyla included Bathyarchaeota Biosorption of some heavy metals from media with high salt concentrations by halophilic Archaea. Annual Review of Microbiology. This article has been cited by other articles in PMC.
Location of sampling sites in Poyang Lake and its tributaries. The low content 751–1 Pb in sites NP and GJ may be also due to the presence of Halobacteriales, which had the capacity to reduce the concentration of Pb, Cr, Zn, and Ni ions from media with high salinity [ 60 ].
