An update on enzymatic cocktails for lignocellulose breakdown

: Alternative energy sources have received increasing attention in recent years. The possibility of adding value to agricultural wastes, by producing biofuels and other products with economic value from lignocellulosic biomass by enzymatic hydrolysis, has been widely explored. Lignocellulosic biomass, as well as being an abundant residue, is a complex recalcitrant structure that requires a consortium of enzymes for its complete degradation. Pools of enzymes with different specificities acting together usually produce an increase in hydrolysis yield. Enzymatic cocktails have been widely studied due to their potential industrial application for the bioconversion of lignocellulosic biomass. This review presents an overview of enzymes required to degrade the plant cell wall, paying particular attention to the latest advances in enzymatic cocktail production and the main results obtained with cocktails used to degrade a variety of types of biomass, as well as some future perspectives within this field.
