主　　题：cellulosic hydrolysis sweet sorghum ethanol SSF phosphoric acid hydrolysis 

摘      要：In this work,the ethanol production from sweet sorghum residue was *** sorghum res-idue was hydrolyzed with phosphoric acid under mild *** liquid hydrolysate was fermented by Pachysolen tannophilus,and the hydrolysis residue was fermented by the simultaneous saccharification and fer-mentation(SSF)using Saecharomyces cerevisiae with cel-lulase(60 FPU/g dry materials).Orthogonal experiments were carried out to investigate the effects of main reaction condition factors,such as temperature,acid concentra-tion,time and dry-matter content,on the reducing sugar *** results show that the optimal reaction condi-tions should be 120℃,80 g/L,80 min and 10%,*** these conditions,0.3024 g reducing sugar/g dry material was *** liquid hydrolysate was then fermented by *** with the highest ethanol concentration of 14.5 g/*** a water-insoluble solid con-centration of 5%,5.4 g/L ethanol was obtained after 12 h of *** total ethanol yield was 0.147 g/g dry material,which would be beneficial for the application of ethanol production from sweet sorghum residue.
