Abstract
The performances of the powerlaw formalism method (PLFM) and NewtonRaphson method (NRM) are compared by applying them to a nonlinear least square problem for determination of the maximum reaction rate, Vm, and Michaelis constant, Km, in an immobilized enzyme system following MichaelisMenten kinetics. A detailed numerical investigation indicates that 1) the accuracies of the solutions (Vm and Km) obtained by these two methods are almost the same and very high; 2) however, the rate of convergence in PLFM is higher than that in NRM; and 3) the basin of attraction for PLFM is much wider than that of NRM. Advantages of PLFM are discussed based on the experimentaldata in the hydrolysis of soluble starch by glucoamylase immobilized on a porous honeycomb monolith. The result suggests that the nonlinear leastsquare method combined with PLFM is useful for many optimization problems in engineering fields.
