Species InformationThe Methanobrevibacter smithii ATCC 35061 genome is 1.85 Million bp long and contains approximately 1835 predicted genes.
Taxonomy: Archaea; Euryarchaeota; Methanobacteria; Methanobacteriales; Methanobacteriaceae; Methanobrevibacter.
Sequencing: The sequence was released 06/04/2007 by the Washington University (WashU), and was described in Proc Natl Acad Sci U S A 104:10643-8 (2007) Samuel BS, Hansen EE, Manchester JK, Coutinho PM, Henrissat B, et al.."Genomic and metabolic adaptations of Methanobrevibacter smithii to the human gut." Abstract: The human gut is home to trillions of microbes, thousands of bacterial phylotypes, as well as hydrogen-consuming methanogenic archaea. Studies in gnotobiotic mice indicate that Methanobrevibacter smithii, the dominant archaeon in the human gut ecosystem, affects the specificity and efficiency of bacterial digestion of dietary polysaccharides, thereby influencing host calorie harvest and adiposity. Metagenomic studies of the gut microbial communities of genetically obese mice and their...

Abstract: Fecal specimens from nine adults were examined for the presence of methanogenic bacteria. Enrichment cultures of five specimens produced methane in 5 days. Of these five specimens, three were tested and produced methane during a short-term incubation. Four specimens did not produce methane in either short-term incubation or in enrichment culture. Each methanogenic culture contained methanogens similar in morphology to organisms of the genus Methanobrevibacter and showed factor-420...

CreditsThe Archaeal Genome Browsers at UCSC were developed by members of theLowe Lab (Kevin Schneider,Katherine Pollard, Andy Pohl, Todd Lowe) and Robert Baertsch, with significant support fromthe UCSC Human GenomeBrowser group.The Archaeal Browsers are run by a slightly modifiedversion of the UCSC Human GenomeBrowser system. All queries, bug reports, content corrections, suggested improvements,and new track data submissions should be sent to Todd Lowe (lowe@soe.ucsc.edu).If you use the browser in your published research, please cite ourpublication in the Nucleic Acids Research DatabaseIssue.
