英文摘要	Viscosity trends in alkali-pretreated sugarcane bagasse (scb) slurries undergoing high solids fed-batch enzymatic hydrolysis were measured for a range of solids loading from 15% to 36%. solids liquefaction times were related to system viscosity changes. the viscosity decreased quickly for low solids loading, and increased with increasing solids content. fed-batch hydrolysis was initiated with 15% solids loading, and an additional 8%, 7% and 6% were successively added after the system viscosity decreased to stable values to achieve a final solids content of 36%. two enzyme-adding modes with 8.5 fpu/g solid were investigated. the batch mode with all enzyme being added at the beginning of the reaction produced the highest yields, with approximately 231.7 g/l total sugars and 134.9 g/l glucose being obtained after 96 h with nearly 60% of the final glucan conversion rate. this finding indicates that under the right conditions, the fed-batch strategy might be a plausible way to produce high sugars under high solids.
