Crynodeb
A recently established mixed culture fermentation (MCF) model has been modified to account for the role of different electron carriers in the process. The MCF-model predicts the product spectrum as a function of the actual environmental conditions using a thermodynamic optimization criterion while satisfying a number of constrants. Other improvements made to the original model are the inclusion of formate as fermentation end-product, and gas-liquid mass transfer. The model is adequately capable of reproducing experimental results in terms of butyrate and formate versus hydrogen/carbon dioxide production. The model is not capable of predicting the production of an ethanol/acetate mixtue as measured at higher pH-values, suggesting specific biochemical control. Catabolic acetate production can potentially be explained by anabolic requirements for a specific electron donor like NADH.
