Cultivation graphs for Aspergillus niger F16. A Graph of response surface from the factorial design 32, showing the influence of variables, that is, temperature and inducer, on the response variable (total proteins). B Pareto Chart with linear (L) and quadratic (Q) effects of each of the tested variables. C Graph showing the influence of temperature as a function of the response variable (total proteins). D Likewise, the graph shown the influence of the inducer as a function of the response variable (total proteins)
