Abstract
ABSTRACT Bioconversion of lignocellulose biomass to ethanol is significantly hindered by the structural and chemical complexity of biomass, which makes these materials a challenge to be used as feedstocks for cellulosic ethanol production. Cellulose and hemicellulose, when hydrolysed into their component sugars, can be converted into ethanol through well established fermentation technologies. However, sugars necessary for fermentation are trapped inside the crosslinking structure of the lignocellulose. Hence, pre-treatment of biomass is always necessary to remove and/or modify the surrounding matrix of lignin and hemicellulose prior to the enzymatic hydrolysis of the polysaccharides (cellulose and hemicellulose) in the biomass. Pre-treatment refers to a process that converts lignocellulose biomass from its native form, in which it is recalcitrant to cellulose enzyme systems, into a form for which cellulose hydrolysis is much more effective. In general, pre-treatment methods can be classified into three categories, including physical, chemical, and biological pre-treatment. The subject of this paper emphasizes the biomass pre-treatment in preparation for enzymatic hydrolysis for cellulosic ethanol production. It primarily covers the impact of biomass structural and compositional features on the pre-treatment, the characteristics of different pre-treatment methods, the pre-treatment study status, challenges, and future research targets.
