| 英文摘要 | lignin layers surrounding hemicelluloses and cellulose in the plant cell walls protect them from deconstruction. this recalcitrance to sugar release is a major limitation for cost-effective industrial conversion of lignocellulosic biomass to biofuels. many literatures had reported the contribution of lignin removal to cellulose accessibility to enzyme, but less to the hemicellulose hydrolysis. herein, beech xylan with lignin addition, partly delignified sugarcane bagasse (sb), energy sorghum hybrids (esh) were treated in liquid hot water (lhw) to investigate the effect of lignin on hemicellulose decomposition. the addition of lignin can enhance the low degree of polymerization of xylooligomers production resulted from the acid catalyzed cleavage of lignin-derived acidic products. however, a negative correlation was observed initially between the lignin level and the total xylose yield from esh. furthermore, samples with lignin addition or high lignin content had a great resistant to harsh reaction environment, about 93.5% total xylose lost but only 52.3% released due to the lack of lignin protection for the sample with 100% lignin removal.
