Figure 1From: Lignosulfonate-mediated cellulase adsorption: enhanced enzymatic saccharification of lignocellulose through weakening nonproductive binding to ligninpH-dependent net surface charge of Cel and LS. Zeta potential was measured at 25°C using laser Doppler microelectrophoresis. The 0.1 M H2SO4 and 0.1 M NaOH were used for pH adjustment prior to measurements. Cel, cellulase; LS, lignosulfonate.Back to article page
