Guzahn The confined influence was confirmed by the RDA results, although the physicochemical factors in the first two RDA axes, respectively, explained Shannon and Simpson index showed high archaea diversity in all samples, except for Site 1 Table 2. Other reports suggested that some members of the Thermoplasmatales may represent a new order of methanogens that can utilize methylamine [ ]. Pacearchaeota and Woesearchaeota were previously reported from saline sediments, but in surface waters of some lakes they were also detected [ 40 ]. Both central lake and tributary estuaries are included in this study. Archaea is found bgl an important role in global biogeochemical processes, such as methanogenesis and methane oxidation [ 2 ], sulphate reduction [ 3 ], and ammonia oxidation [ 45 ].

Morr The main composition of the whole archaeal community was also shown in the pie chart. The obtained raw sequences were analyzed using Bellerophon http: The phylum Euryarchaeota could be deeply divided into six orders, Methanomicrobiales Metabolic, phylogenetic, and ecological diversity of the methanogenic Archaea. The objective of the present study is to characterize the archaea community structure in sediments of Poyang Lake and estimate the influence of surface sediment properties on the spatial distribution of archaea community.

Submission Accession List — DRA Search Phylogenetic analysis of the sediment archaea 16S rRNA gene libraries revealed high diversity in Poyang Lake, and the majority of archaea community belonged to common groups of river and lake sediments.

The new genome reading of Thermoplasmatales cells has revealed the genes that encode extracellular protein-degrading enzymes and which could enable them to survive on sedimentary detrital proteins [ 37 ].

In sediments of Lake Kivu and Lake Bled, Methanobacteriales, Methanosarcinales, and Thermoplasmata all played a big part in the whole archaea community; Crenarchaeota and Thaumarchaeota collectively take a small proportion compared with Euryarchaeota [ ]. Bti i i-i T. Bathyarchaeota was believed to have an organic heterotrophic lifestyle and can degrade buried organic carbon and detrital proteins in subsurface sediments [ 36 , 37 ].

The dotted lines stand for the environmental background values of Poyang Lake. Poyang Lake in China. Predominant archaea in marine sediments degrade detrital proteins. Genome Biology and Evolution. However, the hydrological bgj of Poyang Lake changed dramatically in recent years, and the overall water areas also decreased. Annals of the New York Academy of Sciences.

Pacearchaeota and Woesearchaeota were previously reported from saline sediments, but in surface waters of some lakes they were also detected [ 40 ].

Other components of archaea community were Woesearchaeota, Pacearchaeota, Thaumarchaeota, suspended Lokiarchaeota, Aigarchaeota, and Unclassified Archaea. Afterwards, samples were divided into two gbi.

The sediment archaea community showed diverse distribution patterns among seven sampling sites. Methylotrophic methanogenic Thermoplasmata implicated in reduced methane emissions from bovine rumen. Bathyarchaeota MCG comprised a large number of phylotypes from anoxic environments and can be divided up to 17 subgroups [ 35 ].

Methanogenic pathway and bgu community structure in the sediment of eutrophic Lake Dagow: The content of Zn from all seven sites remarkably exceeded the background value, and Pb content from most also exceeded the background value except for sites NP and GJ.

Methanosarcinales and Methanomicrobiales usually draw energy from anaerobic oxidation of methane AOM and are coupled with bacterial sulphate reduction [ 44 ]. Meanwhile, the eutrophication and pollution caused by agriculture, aquiculture, and industrial activities threatened the water safety [ 17 — 19 ].

Heterotrophic Archaea dominate sedimentary subsurface ecosystems off Peru. The sediment archaea from 13 plateau freshwater lakes comprised 16 classified phyla and classes; MCG and Thermoplasmata were the most predominant groups [ 13 ]. Genomic DNA was extracted from 0.

Mezit Lake sediment is an active place with a high abundance of microorganisms, which is subjected to the changes of organic matter degradation, resuspension, and redeposition of various chemicals [ 9 bgj. Three samples were collected at each site under aseptic conditions and put on ice in a container and transported to the lab immediately. The seven phyla included Bathyarchaeota Archaeal community diversity and abundance changes along a natural salinity gradient in estuarine sediments.
