(a) Response surface for the effects of cellobiose (%) and yeast extract (%) at 1.6% (NH4)2SO4 and pH 6 on the specific activity after 240 h of incubation. (b) Response surface for the effects of cellobiose (%) and (NH4)2SO4 (%) at 0.5% yeast extract and pH 6 on the specific activity after 240 h of incubation. (c) Response surface for the effects of cellobiose (%) and pH at 1.6% (NH4)2SO4 and 0.5% yeast extract on the specific activity after 240 h of incubation. (d) Response surface for the effects of yeast extract (%) and (NH4)2SO4 (%) at 1.75% cellobiose and pH 6 on the specific activity after 240 h of incubation. (e) Response surface for the effects of yeast extract (%) and pH at 1.75% cellobiose and 1.6% (NH4)2SO4 on the specific activity after 240 h of incubation. (f) Response surface for the effects of (NH4)2SO4 (%) and pH at 1.75% cellobiose and 0.5% yeast extract on the specific activity after 240 h of incubation.
