For the design of an enzyme reactor a detailed knowledge of the kinetic parameters of the catalyst under operational conditions is essential. For technical applications high initial substrate concentrations and high degrees of conversions are desirable, in order to save reactor volume and energy in recovery processes. Most of the kinetic data available in the literature have been derived from dilute solutions under initial rate conditions. These data cannot be extrapolated with confidence for technically interesting concentrations because substrate as well as product-inhibition may occur, which would not be observed in dilute solutions and by initial rate measurements. Because of this difficulty effective and fast methods to obtain significant data for technical applications have been developed based on-line rate determinations. Such extensive treatment has proved necessary for the following enzymes: alanine dehydrogenase, formate dehydrogenase and alpha-glucosidase, indicating that we are dealing with a general phenomenon.
