heal.abstract The possibility of optimizing certain fermentation conditions towards the total unit productivity of several enzymes has been investigated. As a model system, we used a particular strain of Aspergillus niger capable of simultaneously producing significant levels of superoxide dismutase, glucose oxidase, and catalase. The fermentation parameters used in the optimization were the fermentation time, and the concentration of carbon and nitrogen source. The optimum set of fermentation parameters for maximum production of each enzyme has initially been determined. The introduction of a value factor for each enzyme unit of specific purity yields the conclusion that there is a point in the parameter space, different from that of optimum production of each separate enzyme, where a maximum exists for the total unit value of the three enzymes produced. This result suggests that multienzyme optimization in fermentations may effectively reduce the cost of the production process. en
