Description 849-864
Biomass pretreatment (BP) plays a crucial role in a lignocellulose feedstock-based biorefinery (LCFBR) for processing of
three major output streams (cellulose, hemicelluloses and lignin) into chemicals and biofuels. BP includes processing of
lignocellulosic material (LCM) under aqueous, dilute acid or alkaline media to obtain a cellulosic fraction, which is then
fermented to produce bioethanol. Hemicellulose is usually treated as a secondary stream due to lack of efficient fermentation of
hemicellulosic sugars to ethanol. This review provides BPs assuming that hemicellulose stream should be integrated in LCFBR
as a primary fraction for converting into value-added compounds other than bioethanol. Different LCM treatments are
analyzed foreseeing bio-based products possible to obtain from hemicellulose path.
