Response Surface Methodology (RSM) based on a three-level, three-variable Box and Behnken Factorial Design (BBFD) was used to evaluate the interactive effects of corn stalk: bran ratio, tween80 and temperature on the cellulase production by solid fermentation. The optimum conditions derived via RSM were: corn stalk: bran ratio 1.29:1, Tween80 11.05 &muL and temperature 31 C for carboxymethyl cellulase (CMCase) and corn stalk: bran ratio 0.77:1, Tween80 12.54&muL and temperature 32 C for Filter Paper Activity (FPA). The actual experimental yield was 406.42 U/g for CMCase and 93.62 U/g for FPA under optimum condition, which compared well to the maximum predicted value of 405.67 U/g and 91.29 U/g. The cellulase yield under optimal conditions was 1.45 fold for CMCase and 1.33 fold for FPA to the control.
