Rates of enzymatic hydrolysis of crystalline (C), swollen (0 h), and gelatinized (5 h) cellulose. Crystalline cellulose was swollen in TFA at − 20 °C for 15 h. Gelatinized cellulose was prepared from swollen cellulose by heating at 55 °C for 5 h. Cellic® Ctec2 (Novozymes) (18 or 1.8 FPU/g glucan) was added to 5 mg of cellulose samples in 2 mL of 50 mM sodium citrate and incubated at 50 °C for up to 72 h. Samples were withdrawn at designated intervals for assay cellulose and solubilized glucose [54]. Panel (a) shows samples that were not dried prior to enzymatic hydrolysis. Panel (b) shows samples that were freeze dried prior to hydrolysis
