Characteristic growth and enzyme production parameters of T. reesei Rut-C30 on OrganoCat and OrganoSolv cellulose. T. reesei Rut-C30 was grown on 5 g L⁻¹ glucose and 30 g L⁻¹ α-cellulose, 33 g L⁻¹ OrganoCat-cellulose, 33 g L⁻¹ OrganoSolv-cellulose, supplemented with 0.3 g L⁻¹ urea, 0.1 % (v/v) tween 80 and 2 g L⁻¹ peptone. a Oxygen transfer rate (OTR) and protein content in the culture supernatant; b pH and filter paper activity. The OTR was measured in duplicates. As the maximum mean error was as low as 1 mmol L⁻¹ h⁻¹, average values are shown. For clarity only every second measuring point over time is represented by a symbol. Error bars represent standard deviation of technical triplicates. Culture conditions: modified Pakula medium, 250 mL flask, filling volume 20 mL, shaking frequency 350 rpm, shaking diameter 50 mm, inoculum 10⁶ spores mL⁻¹, and 30 °C
