Abstract
Deconstruction of lignocellulosic biomass using enzymatic catalysis can offer several advantages as compared to chemical catalysis in terms of product selectivity, production cost and sustainability issues. This contribution aims to provide an account of current developments in the understanding of plant biomass microstructures and the impact of various enzymatic processes on cellulose decrystallization. Critical problems, including biomass recalcitrance, and operational factors, including potential solutions to improve their effectiveness as alternatives in future biorefineries, will be also discussed.

Enzymatic cellulose decomposition primarily relies on glycoside hydrolases (GHs) and oxidative enzymes
Summary
Deconstruction of lignocellulosic biomass using enzymatic catalysis can offer several advantages as compared to chemical catalysis in terms of product selectivity, production cost and sustainability issues. Recent biocatalytic attempts to valorize lignocellulosic biomass for the production of chemicals and biofuels have focused on identifying enzymes with enhanced hydrolytic capabilities [1]. Physical and chemical processes are generally more efficient in terms of total conversion but inherently energy consuming, with a large generation of by-products.
