Addition of α-cellulose to cultures of T. reesei, A. terreus, and P. verruculosum. After 7 days of cultivation, additional 120 g L⁻¹ α-cellulose was supplemented to two of the biological triplicates (indicated by an arrow). After addition, the OTR is marked with a lighter corresponding color. For clarity of the depicted values, only every fifth measuring point is represented by a symbol. Culture conditions: modified Pakula medium with 5 g L⁻¹ glucose and 30 g L⁻¹ α-cellulose, 250-mL flask, filling volume 20 mL, shaking frequency 350 rpm, shaking diameter 50 mm, inoculum 10⁶ spores mL⁻¹, and 30 °C
