Archaebacteria are primitive, single-celled microorganisms that are prokaryotes with no cell nucleus. Each archaea has the ability to live in ver.

During attempts to obtain novel, human-associated species of the domain Archaea, a coccoid micro-organism, designated strain B10T, was isolated in pure culture from a sample of human faeces collected in Marseille, France. On the basis of its phenotypic characteristics and 16S rRNA and mcrA gene sequences, the novel strain was classified as a methanogenic archaeon.

Comparative Genomic Analysis of Members of the Genera Methanosphaera and Methanobrevibacter Reveals Distinct Clades with Specific Potential Metabolic Functions.

Methanosphaera stadtmanae is detected in up to a third of western adults, with abundance appearing to increase from adulthood into old age (Dridi et al., 2009; Mihajlovski et al., 2010). It only produces CH 4 by reducing methanol (derived from microbial degradation of pectin) in the presence of H 2, and needs acetate (CH 3 COOH) and CO 2 as carbon sources ( Fricke et al., 2006 ).

Methanobrevibacter smithii (M. smithii) and Methanosphaera stadtmanae (M. stadtmanae) are the two methanogens usually detected in the human gut. M. smithii is the predominant methanogen in the human colon. Next to H 2,, formate can be used for the methanogenesis as well. The produced CH 4 and the remaining H 2 are excreted in breath and flatus.

Catalyzes the NAD(P)H-dependent reduction of dihydroxyacetonephosphate (DHAP or glycerone phosphate) to glycerol 1-phosphate (G1P). The G1P thus generated is used as the glycerophosphate backbone of phospholipids in the cellular membranes of Archaea.

Methane is produced in the foregut (rumen) of ruminants by methanogens, which act as terminal reducers of carbon in the rumen system. The multistep methanogenesis pathway is well elucidated, mainly from the study of non-rumen methanogens, but the adaptations that allow methanogens to grow and persist in the rumen are not well understood.

In addition, the identification of novel uncultured methanogens in the rumen (23, 33, 40) suggests that the understanding of the methanogenic ecology is limited. Cattle with higher feed efficiencies are reported to produce 20 to 30% less methane (9, 24).

The enrichment analysis can be computed using a pre-compiled reference, or alternatively you can provide a background set. (Note that organism-based backgrounds are available only for certain KEGG and Biocyc annotations).
