Název v původním jazyce

Mechanical pre-treatment of lignocellulosic biomass towards enzymatic/fermentative valorization

Popis výsledku v původním jazyce

Lignocellulosic biomass (LCB) has the potential to replace fossil fuels, thanks to the concept of biorefinery. This material is formed mainly by three components: cellulose, lignin, and hemicellulose. To make it viable to be valorized, LCB needs to be pre-treated to release cellulose and hemicellulose, in an efficient way. Among the possible pretreatments available, mechanical treatments have proved to be one of the main alternatives. This kind of pretreatments use mechanical force to break the primary cell wall, making cellulose more accessible to posterior treatments, because of the increased specific surface area and the reduction of the crystallinity, resulting in an increase of the efficiency of the final process. The importance of the pretreatment is critical, since the improvement of the following process would lead to reduction of the equipment size, residues, and residence time. After the pre-treatment, the main valorization path can be performed. These paths are usually classified as: Chemical, thermal, Enzymatic and Fermentative. Enzymatic hydrolysis and fermentation are the most used and are usually combined, to produce biogas and biofuels. In this review, mechanical treatments on LCB will be shown, focusing mainly on those who aim to increase enzymatic digestion/fermentation of the pretreated material, to choose the best one according to the feedstock available, and to show the wide range of products that can be obtained from LCB.
