| Abstract: | The effect of γ-rays radiation pretreatment on enzymatic hydrolysis of corn straw for producing sugar was studied. The relationship between irradiation-dosage and content of reducing sugar was investigated in DNS method. After 1000 kGy irradiation, the content of reducing sugar reached about 317.35%. A synergistic effect between irradiation and enzyme was observed. The reducing sugar yield after enzymatic hydrolysis reached 20.51% when the corn straw powder （0.15 mm） irradiated with a dose of 1 000 kGy. The result shows that the irradiation had significant influence on enzymatic hydrolysis of corn straw. At the 500 kGy preirradiation, compared with initial yield, the maximum sugar yield of sample had increased by 13.68% while the irradiated corn straw stored in 20 days. |
