Computer-Controlled Fed-Batch Cultivation of a Recombinant Escherichia coli for Overproduction of Human Interleukin-2
To determine the optimal feeding policy in fed-batch fermentation, a variety of problem-specific methods have been proposed in recent years. A problem closely related to the glucose feeding policy is the excre...
