Growth kinetic parameter estimation of Candida rugopelliculosa using a fish manufacturing effluent

Abstract

A fourth order Runge–Kutta approximation was used to determine the Monod kinetics of Candida rugopelliculosa by using unsteady state data from only one continuous unsteady state operation at a fixed dilution rate. The maximum microbial growth rates, μmax, and half saturation coefficient, Ks, were 0.82 ± 0.22 h−1 and 690 ± 220 mg soluble chemical oxygen demand (SCOD) l−1, respectively. The microbial yield coefficient, Y, and microbial decay rate coefficient, kd, were 1.39 ± 0.22 × 104 cells mg−1 SCOD and 0.06 ± 0.01 h−1, respectively.
