Glucose yields of enzymatic hydrolysis of the control, pretreated (a), and post-treated substrates (b). Control-S extractive-free raw material, S substrates obtained by the direct dilute acid pretreated materials under different conditions, Control-R substrate obtained by the alkali treatment raw material without dilute acid pretreatment, R substrates obtained by the alkali post-treated substrates from the dilute acid pretreated substrates
