Optimization of Enzymatic Saccharification of Alkali Pretreated Typha angustifolia for Glucose Production

Arrisa Sopajarn and Chayanoot Sangwichien
Abstract—Lignocellulose ethanol is significantly sustainable bio-fuel. It is an environmentally friendly. This work is to develop a hydrolysis process of pretreated lignocellulose to ethanol production from narrow leaved cattail as a biomass material. Response surface methodology (RSM) with a central composite design (CCD) was followed to optimize the enzymatic saccharification process in order to obtain high glucose yield. Three independent variables (cellulase, β-glucosidase and temperature) that operating condition, vary at CCD five levels (-α, -1, 0, +1, +α). The optimum values for the predicted variables for glucose and xylose released were: cellulase loading 17.5 FPU/g substrate, β- glucosidase loading 0 U/g substrate and hydrolysis temperature 55°C. Under these optimal conditions, glucose and xylose yield reached to 413.25 mg/ g substrate and 75.48 mg/g substrate, respectively. The results of a confirmation experiment under the optimum conditions agreed with model predictions.

Index Terms—Enzymatic saccharification, lignocellulose, RSM, narrow leaved cattail, glucose produced.
