✦ Synopsis

Complete anaerobic digestion of complex organic matter by combined activities of successive populations of acidogenic, intermediate and methanogenic bacteria results in the formation of methane, carbon dioxide and water. In many cases methane arises from the fermentation of acetate as one of the main intermediate products of anaerobic digestion. However, methane can also be produced from methanol, from formate or from a mixture of carbon dioxide and molecular hydrogen, be it partly by different methanogens, adapted to these substrates. Some of the substrates suitable for methanogens also appeared to be utilized by non-methanogens.
