The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture of Penicillium purpurogenum GH2, using Czapek-Dox media with D-xylose as a carbon source. An experimental design with a factorial fix was used： three pH values （5, 7, and...
