本研究以甘蔗渣为原料，利用超声波辅助酸水解法制备糖单体。SCB进行超声波辅助碱预处理。在固体含量中观察到的纤维素和半纤维素回收率分别为99%和78.95%，并且在预处理期间观察到的木质素去除率为约75.44%。将获得的固体内容物进行超声波辅助酸水解。在优化条件下，己糖和戊糖的最大产率分别为理论产率的69.06%和81.35%。发现所获得的水解产物含有非常少的抑制剂，这改善了生物乙醇生产，并且观察到的乙醇产率为0.17g/g预处理的SCB。
In this study, the production of sugar monomers from sugarcane bagasse (SCB) by sono-assisted acid hydrolysis was performed. The SCB was subjected to sono-assisted alkaline pretreatment. The cellulose and hemicellulose recovery observed in the solid content was 99% and 78.95%, respectively and lignin removal observed during the pretreatment was about 75.44%. The solid content obtained was subjected to sono-assisted acid hydrolysis. Under optimized conditions, the maximum hexose and pentose yield observed was 69.06% and 81.35% of theoretical yield, respectively. The hydrolysate obtained was found to contain very less inhibitors, which improved the bioethanol production and the ethanol yield observed was 0.17 g/g of pretreated SCB.
