Fig. 8From: Optimal process design space to ensure maximum viability and productivity in Penicillium chrysogenum pellets during fed-batch cultivations through morphological and physiological controlDependence of viable layer on specific substrate uptake rate. Red triangles indicate bioreactor cultivations at low dissolved oxygen set points (left). Coefficient plot of the factors ‘P/V’, ‘qs’ and ‘dO2’ and their effects on the viable pellet layer (right). Interaction terms were omitted because they were not significant according to MODDEBack to article page
