Fig. 8From: Camptothecin bioprocessing from Aspergillus terreus, an endophyte of Catharanthus roseus: antiproliferative activity, topoisomerase inhibition and cell cycle analysisThe main effects of different variables on CPT production by A. terreus with the Plackett–Burman experimental design. A Pareto chart illustrates the order of significance of each variable. Normal plot (B) and half-normal (C) of probability with standardized effect. D Box-Cox of power transform. E Normal plot of the internally standardized residuals. F Plots of residuals versus predicted response of CPT by A. terreus Plot of the correlation of the predicted and actual camptothecin yield by A. flavus. E Normal plot of the residualBack to article page
