Abstract

Normally, propionate and butyrate account for approximately 20% of the methane produced in an anaerobic digestion. The degradation of these volatile fatty acids involves at least two groups of bacteria, the obligately hydrogen-producing acetogenic bacteria oxidizing the acids and the methane-producing bacteria utilizing the hydrogen produced (for a review see reference 1). Owing to the unfavorable thermodynamics of fatty acid oxidation under standard conditions, the metabolism of the acetogenic bacteria demands a low partial pressure of hydrogen normally maintained by the hydrogen — utilizing methanogenic bacteria.
