Hemicellulase for pretreatment of lignocellulosic biomass: Mini Review

Pretreatment of lignocellulosic biomass is an important stage in bioethanol production and other bioconversions. One method that can be used is the enzymatic method. This method has a selective, efficient, and environmentally friendly approach. Hemicellulolytic enzymes such as xylanase and mannanase play an important role in hydrolyzing hemicellulose components, thereby opening up cellulase enzymes access to cellulose. The use of xylanase has been shown to increase sugar release from biomass such as rice straw and bagasse, while mannanase shows high effectiveness on mannan rich substrates such as palm kernel meal and coffee grounds. The combination of these two enzymes with cellulases accelerates saccharification and increases fermentable sugar conversion yields, making it a potential strategy in industrial scale biomass processing.
