โœฆ Synopsis

Fermentation kinetics of Clostridium forrnicoaceticum grown on lactate at pH 7.0 and 35ยฐC was studied. Acetate was the only fermentation product and its production was growth associated. The growth of this bacterium was insensitive to the lactate concentrations studied, but was inhibited by acetic acid. A Monod-type expression with product inhibition similar to the noncompetitive inhibition of enzyme kinetics was used to model the batch fermentation. An integrated equation was developed and used to help estimating the kinetic parameters in the model. This mathematical model can be used to simulate the homoacetic fermentation of lactate by C. formicoaceticum at pH 7.0 and 35ยฐC.

## Abstract Mathematical modeling of the thermopolymerization of FM and CMFMA was carried out using a crossโ€linked kinetic model proposed for the photoโ€initiated polymerization of acrylโ€furanic compounds. In this model, the photochemical initiation step was substituted by a thermal one and it was a
