Fibrobacter Succinogenes
''Fibrobacter succinogenes'' is a cellulolytic bacterium species in the genus ''Fibrobacter''. It is present in the rumen of cattle. ''F. succinogenes'' is a gram negative, rod-shaped, obligate anaerobe that is a major contributor to cellulose digestion. Since its discovery in the 1950s, it has been studied for its role in herbivore digestion and cellulose fermentation, which can be utilized in biofuel production. History ''Fibrobacter succinogenes'' was isolated in 1954 by M.P. Bryant and R.N. Doetsch from bovine rumen at the University of Maryland. They isolated 8 different strains – S23, S61, S85, S111, S121, C2, M13, and M34, all of which belonged to one species – ''Bacteroides succinogenes.'' This species would later be renamed ''Fibrobacter succinogenes.'' S85 would soon become a model strain for research, and it continues to be representative of wild type species. Genome The genome of ''F. succinogenes'' is 3.84 Megabasepairs and is predicted to consist of 30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
