Steam-explosion Pretreatment of Triarrherca sacchariflora
摘要
Abstract
The effects of steam-explosion pretreatment on the composition and enzymatic hydrolysis efficiency of solid residues of Triarrherca sacchariflora were investigated in the experiments.The fiber shape and structure have been charac-terized with scanning electron microscopy(SEM),as well as infrared and X-ray diffraction(XRD)spectrum methods.The results showed that after the steam explosion pretreatment,most hemicellulose was degraded,a fraction of lignin was also solubilized,and the relative content of cellulose was increased.The fiber surface and cell wall of Triarrherca sacchariflora were broken in various extents and the cellulose crystallinity was reduced,which were helpful to increasing the efficiency of enzymatic hydrolysis.The enzymatic hydrolysis efficiency of the untreated material was only 14.38%,,but the highest enzy-matic hydrolysis efficiency of 88.95%, was obtained after the steam-explosion pretreatment.关键词
