Description
Coloured scanning electron micrograph (SEM) of the human intestine archaea Methanobrevibacter smithii. M. smithii is the main human gut (intestine) archaeon (from the archaea domain) that is a methanogen (hydrogenotroph). It recycles the hydrogen in methane and allows for an increase in energy extraction from nutrients. It plays a role in the digestion of polysaccharides (complex sugars) by consuming the end products of bacterial fermentation. The human gut flora consists of three main groups of hydrogen consuming, or hydrogenotrophic, microbes: methanogens; a polyphyletic group of acetogenic bacteria; and sulphate reducing bacteria. Magnification: x5, 335 when shortest axis printed at 25 millimetres.
