Abstract

Acetogens are anaerophyte with different morphological, nutritional and physiological properties. The H2-CO2-dependent acetogenesis is more exergonic than H2-CO2-dependent methanogenesis. Acetogens can be found in almost all anoxic environments including animal gastrointestinal systems. Acetogenesis often out-competes methanogensis in the gut and stomach of termite, ostrich and kangaroo, and represent 7% to 33% of maintenance energy requirements of these animals. There are acetogens in the rumen. In order to answer if the reductive acetogenesis could be intensified in the rumen, the phylogeny of acetogens, the relationship between acetogens and methanogens, and the strategy of utilizing acetogens were reviewed in this paper.

Key words: acetogen; methanogen; rumen
