Planktonic archaea include predominantly Marine Group I Thaumarchaeota (MG I) and Marine Group II Euryarchaeota (MG II), which play important roles in the oceanic carbon cycle. MG I produce specific lipids called isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs), which are being used in the sea surface temperature proxy named TEX86 ...

Cultivation of moonmilk-born non-extremophilic Thaum and Euryarchaeota in mixed culture
Anaerobe, 2014PCR-DGGE, qPCR and sequencing highlighted a quite homogenous archaeal community prevailing in secondary calcite deposits, so-called moonmilk, within the cold alpine Hundalm cave in Tyrol (Austria). Furthermore, the depth profile of this moonmilk could prove that the Archaea are located in oxygen-rich near- and oxygen-depleted sub-surface layers.

A transect from the Tomoe River Mouth through Shimizu Port to Suruga Bay, Japan, was examined between 2005 and 2009 to reveal the population dynamics of Crenarchaeota and Euryarchaeota in an estuary environment. Crenarchaeota tended to increase in abundance in waters deeper than 100 m compared with Euryarchaeota, and comprised 11% of total direct ...

Phylum All. Euryarchaeota phy. nov.
2001The phylum currently consists of seven classes: the Methanobacteria, the Methanococci, the Halobacteria, the Thermoplasmata, the Thermococci, the Archaeoglobi, and the Methanopyri. With the sole exception of the Methanococci, which is subdivided into three orders, each class contains a single order.

Soil Biology and Biochemistry, 2013
Euryarchaeota, as an important and ubiquitous Archaea phylum, contributes substantially to global energy cycling. However, there is a considerable lack of knowledge regarding their biogeographic patterns in terrestrial ecosystems. Here barcoded pyrosequencing was employed to compare the relative abundance, diversity and community composition of ...

Distribution of Cren- and Euryarchaeota in Scots Pine Mycorrhizospheres and Boreal Forest Humus
Microbial Ecology, 2007Archaeal 16S rRNA gene sequences have been found in a variety of moderate-temperature habitats including soil and rhizospheres. In this study, the differences of archaeal communities associated with Scots pine (Pinus sylvestris L.) short roots, different types of mycorrhizospheric compartments, and uncolonized boreal forest humus were tested by direct ...

A heterodimeric DNA polymerase: Evidence that members of Euryarchaeota possess a distinct DNA polymerase [PDF]
We describe here a DNA polymerase family highly conserved in Euryarchaeota, a subdomain of Archaea. The DNA polymerase is composed of two proteins, DP1 and DP2. Sequence analysis showed that considerable similarity exists between DP1 and the second subunit of eukaryotic DNA polymerase δ, a protein essential for the propagation of Eukarya ...

The Distribution and Diversity of Euryarchaeota in Termite Guts
2007Publisher Summary The Euryarchaeota are a critical component of all termite guts, acting as hydrogen sinks in both lower and higher termites. In lower termites and in the wood- and fungus-feeding higher termites, the role of the methanogens appears to be to mop up trace hydrogen.
