Fig. 4From: Amperometric method for the determination of cellulase activity and its optimization using response surface methodThe dependence of the slope of calibration plots on time of signal detection. The cellulose samples were incubated in air-saturated 1% CMC solution in 0.1 M acetate buffer (pH 5.0) at 25 °C; the final concentration of glucose oxidase added was 12 U/mlBack to article page
