Description

Gamma ray radiation and alkali solution pretreatment of wheat straw and its effect on enzymatic hydrolysis were studied. The result shows that the γ-irradiation can significantly decrease the initial concentration of alkali solution and shorten the pretreated time,but the changes in the physical and chemical properties of only irradiated wheat straw are indistinctive. A synergistic effect between irradiation and alkali solution pretreatment was observed. Reducing sugar yield is 78.2%(accounted for theoretical yield) after wheat straw is radiated at a dose of 100 kGy and then with 2%NaOH pretreated for 1 h. (authors)
