Pretreatment of Wheat Straw by γ-ray Radiation and Alkali Solution

Abstract: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
