Kinetics of glucose isomerization to fructose by immobilized glucose isomerase (sweetzyme IT) / Asghar Molaei Dehkordi in Industrial & engineering chemistry research, Vol. 48 N° 7 (Avril 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 7 (Avril 2009) . - pp. 3271–3278 Titre : Kinetics of glucose isomerization to fructose by immobilized glucose isomerase (sweetzyme IT) Type de document : texte imprimé Auteurs : Asghar Molaei Dehkordi, Auteur ; Mehrdad Shoai Tehrany, Auteur ; Iman Safari, Auteur Année de publication : 2009 Article en page(s) : pp. 3271–3278 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Immobilized  glucose  isomerase  Stirred-tank  reactor  Fructose  isomerization  reaction  Arrhenius-like  expressions Résumé : We present the kinetic parameters and equilibrium constant of the enzymatic glucose−fructose isomerization reaction with an immobilized glucose isomerase (IGI), Sweetzyme IT, using a batch stirred-tank reactor following the procedure developed by Dehkordi et al. ( AIChE J. 2008, 54, 1333). The model predictions were compared with the experimental data and fair agreements were found. The influence of temperature on the equilibrium constant and kinetic parameters of glucose to fructose isomerization reaction was investigated. In addition, the frequency factors and the activation energies were determined by using Arrhenius-like expressions. Furthermore, correlations were found for the maximum reaction rate (i.e., Vm) and apparent Michaelis−Menten constant (i.e., Km).
