英文摘要liquid hot water (lhw), an environmental-friendly physico-chemical treatment, was applied to pretreat the sugarcane bagasse (scb). tween80, a non-ionic surfactant, was used to enhance the enzymatic hydrolysis of the pretreated scb. it found that 0.125 ml tween80 /g dry matter could make the maximum increase (33.2%) of the glycan conversion of the lhw-pretreated scb. a self-designed laboratory facility with a plate-and-frame impeller was applied to conduct batch hydrolysis, fed-batch hydrolysis, and the process of high-temperature (50 degrees c) fed-batch hydrolysis following low-temperature (30 degrees c) simultaneous saccharification and fermentation (ssf) which was adopted to overcome the incompatible optimum temperature of saccharification and fermentation in the ssf process. after hydrolyzing lhw-pretreated scb for 120 h with commercial cellulase, the total sugar concentration and glycan conversion obtained from fed-batch hydrolysis were 91.6 g/l and 68.3%, respectively, which were 9.7 g/l and 7.3% higher than those obtained from batch hydrolysis. with saccharomyces cerevisiae y2034 fermenting under the non-sterile condition, the ethanol production and theoretical yield obtained from the process of ssf after fed-batch hydrolysis were 55.4 g/l and 88.3% for 72h, respectively, which were 15.5 g/l and 24.7% higher than those from separate fed-batch hydrolysis and fermentation. the result of this work was superior to the reported results obtained from the lhw-pretreated scb.
