hydrolysis of cellulose mechanisms of enzymatic and acid catalysis
What is a new cellulose–water–enzyme reaction interface?
A new cellulose–water–enzyme reaction interface emerges as the hydrolysis moves inside the solids structure, exposing new cellulose and inert material which may absorb and occupy additional free enzymes.
What is the mechanism of cellulase catalysis?
Mechanisms of cellulase catalysis The cellulase-catalysed heterogeneous reaction is characterised by an insoluble reactant (cellulose) and a soluble catalyst (enzymes). The structural features of cellulose and the mode of enzyme action influence the rate of reaction.
What is the mechanism of enzymatic cellulose degradation?
The mechanism of enzymatic cellulose degradation: purification and some properties of two different 1,4β-glucan glucanohydrolases from Trichoderma viride Enzymatic hydrolysis and recrystallization behavior of initially amorphous cellulose Biotechnol. Bioeng., 27 ( 1985), pp. 177 - 181 Sorption characteristics of cellulases on cellulosic substances
How enzymatic cellulose hydrolysis is influenced by a heterogeneous solid–liquid reaction system?
This paper presents an experimental study and mathematical analysis of how reaction kinetics of enzymatic cellulose hydrolysis are influenced by the changing dynamics and nature of interactions between enzymes, cellulose substrate, products (reducing sugars), and non-hydrolytic materials in a heterogeneous solid–liquid reaction system.
