Methanobrevibacter smithii Balch and Wolfe, 1981 Taxonomic Serial No. Methanobrevibacter smithii is the dominant archaeon in the human gut. However, detection of 16srRNA sequence illustrated that Archaea is a separate independent domain (Chaban and Hill 2012) Abstract The methanoarchaea Methanosphaera stadtmanae and Methanobrevibacter smithii are known to be part of the indigenous human gut microbiota. Although members of the domain Bacteria dominate our gut bioreactors, members of Archaea and Eukarya, and their viruses, are also represented. Selective and non-selective culture methods have been the standard techniques used to For example, the genus Methanobrevibacter, which characterized the most abundant members of the feedstock rumen (R), was represented by three species of which M. smithii and M. boviskoreani showed multiple DGGE band patterns (Figure 2, Band 5–7, 10, 11, 17). Archaea derives from the Greek word achaios, meaning ancient or primitive. 2007: validly published under the ICNP: correct name: Methanobrevibacter oralis Ferrari et al. They do not form a monophyletic group, however, meaning that all the methanogens do not consist of a single ancestor and all its descendants. Rather it is a totally different single-cell life form belonging to the domain archaea. Therefore, the NADP oxidoreductase enzyme may play vital role in the formation of methane in Methanobrevibacter smithii. Methanobrevibacter olleyae Rea et al.
