Abstract

The effects of Tween 80 on the enzymatic hydrolysis of newspaper were tested. By monitoring sugar production it was found that the surfactant (0.1%) increased the rate and extent of cellulose saccharification. Consequently, the rate of enzyme usage in the hydrolysis reactor was improved by 33%. In addition, in the presence of surfactant the recovery of enzymes was higher. Analysis of the enzyme solution showed that with Tween 80 present larger fractions of enzyme remained in solution throughout hydrolysis. Thus, it appears that the surfactant hindered the immobilization of the enzymes on the substrates by reducing the strength of adsorption.
