초록
Pre-saccharification and simultaneous saccharification and fermentation of residual lignocellulosic feedstock Phragmites Australis was assessed and optimized via the multivariate approach of Design of Experiments and Response Surface Methodology. The biomass was pretreated by steam explosion and the logarithm of the severity factor, together with the solid loading and the enzyme dosage were considered as factors in the experimental design. The whole process was carried out on pilot scale units in order to simulate an industrial scenario. A Central Composite Design was employed for the optimization of the three factors. The response was optimized in terms of ethanol production and overall yield with predicted values of 38.95g of ethanol/Kg of total matter loaded into the reactor and 18.07% w/w of ethanol/raw material respectively. The predicted values were confirmed by experimental data.
