| description | This research investigated enhancing the efficiency of enzymatic hydrolysis of wheat straw via freeze–thaw pretreatment and assessed the physicochemical structural changes after this pretreatment. The enzymatic hydrolysis efficiency of cellulose and hemicellulose was enhanced, and hemicellulose was more susceptible to pretreatment. The highest enzymatic hydrolysis efficiency of cellulose and hemicellulose was 57.06 and 70.66%, respectively, at − 80 ℃ for 24 h and − 10 ℃ for 24 h, respectively, which were 2.23 and 3.13-fold higher than the control levels, respectively. Scanning electron microscopy images indicated that transverse cracks appeared before longitudinal cracks with stronger pretreatment conditions, and holes were found in every sample after this pretreatment. Fourier transform infrared spectroscopy and X-ray diffraction analysis indicated that freeze–thaw pretreatment affected both the crystalline and amorphous regions and disrupted the hydrogen bonds within them. This study provides a physical pretreatment method to improve the efficiency of enzymatic hydrolysis of wheat straw. |
