| Abstract: | Summary Acidogenesis during fermentation by a heterogeneous mixed population inoculated at different initial biomass levels was studied. Butyric and lactic acid production and biomass formation were measured. Acidogenesis appeared to be a two step process, lactic acid being produced first, followed by butyric. Fermentation started more rapidly with higher levels of initial biomass, after which the fermentation rate remained unaffected indicating a change in the fermentation profile |
