摘要：

Under the appropriate conditions, hydrolysis of cellulose by cellulase produces glucose according to pscudo first-order reaction kinetics. We used the appearance of glucose to calculate the amount of cellulose available for hydrolysis and the reaction rate of hydrolysis, thus providing a measure of the effectiveness of pretreatment processes. Of the three pretreatment processes tested, rapid streaming for 1 min was more effective than either wet oxidation or autohydrolysis. Solvent extraction of the pretreated woods decreased the effectiveness of cellulase hydrolysis. © 1990, Walter de Gruyter. All rights reserved.
