Kinetic Modelling of Isomerization and Anaerobic Degradation of n-and i-Butyrate

Very clear experimental evidence of isomerization between n-and i-butyrate during their anaerobic degradation was presented. A first experiment in the presence of bromoethane sulfonic acid (BESA), an inhibitor of methanogenesis, allowed the equilibrium distribution of n-, i-butyrate and acetate to be determined. To elucidate the mechanism of the isomerization process, a kinetic analysis was employed. The results suggested that i-butyrate was isomerized into n-butyrate prior to being oxidized to acetate. A mechanism for butyrate degradation, based on the values of the kinetic parameters obtained, was proposed.
