Abstract
A study was undergone to evaluate the role of some fermentation parameters like substrate concentration, enzyme loading, inoeulum size, temperature and rotation speed on ethanol production from deinking paper sludge (PS1) and chemical pulping sludge (PS2) by simultaneous saccharifieation and fermentation using cellulase and Saccharomyces cerevisiae SHY08 -3, The result showed that chemical pulping sludge had good enzymability and ermentability, whereas deinking paper sludge was not susceptible to cellulase. The maximum ethanol production efficiency of PS1 and PS2, 72.71% and 95.97% respectively, were reached at 72h of fermentation under the conditions of substrate concentration of 35 g/L ( according to cellulose) , cellulase loading of 55FPU/gEC ( effective cellulose) ,inoculum size of 6% , temperature of 37℃ and rotation speed of 200 r/min. The results above effectively elucidated that paper sludge has good potential application for ethanol production using simultaneous saccharification and fermentation process.关键词
