摘要：

Hydrolysis of cellulose by cellulase enzymes has been studied in a stirred batch reactor at 50 degrees C. A kinetic model has been devised by which the behaviour of such a reaction could be described. The model has been developed on the basis of shrinking particle theory and Langmuir isotherm concept. The applicability of the model has been tested by comparing the experimental results for diverse reaction systems, obtained in the present study or taken from the literature, and those predicted from the model. The degree of agreement was within +/-2-11%. (C) 2000 Elsevier Science S.A. All rights reserved.
