Résumé : Kinetic properties of Termamyl® 120L were investigated with respect to starch hydrolysis in a batch reactor at substrate concentrations of 50-270 g . dm-³ and enzyme concentrations of 0.17-1 cm³ . dm-³ (i.e., cm³ of Novo Nordisk enzymatic solution per dm-³ of raw cassava starch suspension). A general kinetic expression giving product concentration as a function of time was first developed; an equation relating the reaction rate of each product to the sum of the concentrations of oligosaccharides with a higher degree of polymerisation was then derived. The empirical model satisfactorily fits experimental data for oligosaccharides with a degree of polymerization ranging from 1 to 7.
