| 英文摘要 | Applying mass action law and quasi-steady-state theory, two cellulase kinetic models namely eqs. (5) and (8) were developed on the basis of the first and second order reactions of enzyme deactivation, respectively. the two models are compared according to analysis of experimental data from enzymatic hydrolysis steam-exploded wheat straw. both simulation and prediction results show eq. (8) has much higher accuracy than eq. (5). analysis of initial hydrolysis rate is also in accordance with eq. (8) and against eq. (5). fitted values of k(2) (the rate constant of product formation), k(de2) (the rate constant of enzyme deactivation) and k(e) (the equilibrium constant) determined from eq. (8) are 0.4732 h(-1), 0.4011 l/(h g), and 16.8597 g/l, respectively. the higher the enzyme concentration is, the larger the deactivation rate. (c) 2010 elsevier ltd. all rights reserved. |
