Effects and Characterization of Comminuting Pretreatment on the Fiber Structure of Corn Stover
摘要
Abstract
To investigate the microscopic modification effects of mechanical comminution pretreatment on the fiber structure of corn stover and improve its the resource utilization potential,natural corn stover was selected in this study.With mechanical comminution applied as the pretreatment method,multiple characterization techniques including X-ray diffraction(XRD),fourier transform infrared spectroscopy(FTIR),confocal laser scanning microscopy(CLSM)and scanning electron microscopy(SEM)were adopted to systematically explore the regulatory effects of mechanical comminution pretreatment on the crystal structure,functional group properties and micromorphology of corn stover fibers.The results demonstrated that mechanical comminution pretreatment could disrupt the crystalline structure of cellulose in corn stover,reduce its crystallinity,and expose more amorphous regions and reactive sites.Meanwhile,the treatment could disintegrate intact long strip fibers into micron scale fragmented particles,strip the surface lignin barrier,generate abundant cracks and rough fracture surfaces,and significantly increase the specific surface area of the raw material.This study elucidates the microscopic impacts of enzymatic hydrolysis and fermentation accessivility through mechanical comminution pretreatment,and provides a theoretical basis for the resource utilization of corn stover in scenarios such as feed quality improvement and bioconversion.关键词
