Cultivation graphs for Penicillium sp. F04. A Factorial design 32 graph of the response surface, demonstrating the influence of the variables (temperature and inducer) on the response variable (total proteins). B Pareto Chart showing the linear (L) and quadratic (Q) effects of each of the variables tested. C Graph of temperature influence as a function of the response variable (total proteins). D Graph showing the influence of the inducer as a function of the response variable (total proteins)
