The effect of the relative price of the metabolic product on the optimal fed-batch fermentation policy was studied for the case where the objective function was expressed a linear combination of the total quantities of biomass and metabolic product at the final time. The value of the overall objective function increased as the relative price of the metabolic product rose. A rise in the price of the metabolic product, on the other hand, decreased the switching point, and below a critical value of the relative price, the switching point disappeared. The objective function value per unit relative price, the switching point disappeared. The objective function value per unit relative price decreased as the relative price increased, and reached the limiting value obtained by Yamane (J. Ferment. Technol., 55,587,1977) for the case where the objective function consists of the metabolic product formation only. The optimal feed rate of the limiting substrate decreased with the rise in the relative price. The time-profile of biomass for different values of the relative price followed the same path until a separating point, after which the profile for smaller relative price became larger. The case where the intrinisic yield coefficient is a linear function of the substrate concentration was studied to see its effect on the optimal feed rate policy. As the slope of the function increased, the feed rate decreaed. However the functional form of the yield coefficient has no appreciable effect on the magnitude of the switching point.
