Lignocellulose biodegradation and applications in biotechnology

Lignocellulosic biomass such as agricultural and forestry residues and herbaceous energy crops can serve as low cost feedstocks for production of fuel ethanol and other value-added commodity chemicals. However, development of efficient pretreatment and cost-effective enzymatic conversion of any lignocellulosic biomass to fermentable sugars is a key issue. In this overview chapter, various pretreatment options (dilute acid, steam explosion, alkaline peroxide) and enzymes (mainly cellulases and hemicellulases) involved in lignocellulose degradation are presented Mixed sugars generated by lignocellulose biodegradation are fermented to fuel ethanol, xylitol, 2-3-butanediol and other value-added products. Recent advances in the developments on lignocellulose biodegradation and applications in biotechnology are reviewed.
