Studies on ruminants fed diets containing concentrates or conserved forages indicate that the rumen contains a diversity of acetogens. In the rumen ecosystem, the ubiquitous protozoa are large producers of this metabolic end product.
In the second stage, acetogens and methanogens are built up where volatile fatty acids are converted into methane and carbon dioxide.
