Abstract

Hydrogen is an important intermediate in the degradation of organic material. The oxidation of hydrogen by methanogens creates a low hydrogen partial pressure, which is essential for the breakdown of e. g. propionate and butyrate and which may cause a shift in fermentation products of by hydrogen producing fermentative bacteria. When hydrogen is removed in methanogenic environments, fermentative bacteria, which dispose part of their reducing equivalents as molecular hydrogen form more oxidized and less reduced organic products. In addition, the degradation of reduced organic compounds is only possible in the presence of methanogens.
