Pretreatment of Lignocellulosic Biomass for Bioenergy Production presents the latest developments in the pretreatment of recalcitrant lignocellulosic materials. With an emphasis on commercially ready and near-commercially ready technologies, the book comprehensively analyses the physical, chemical, and biological methods for biomass pretreatment. Divided into three parts, the book begins with a systematic review of the anatomy and ultrastructure of plant cell walls, the chemical structure of cellulose, hemicelluloses, lignin, and lignin-carbohydrate complexes, and the methods for their analysis. Part Two delves into the various pretreatment technologies including physical, physical-chemical, chemical, biological, and combined approaches. The advantages and disadvantages are examined, and industrial and pre-industrial applications are presented. Finally, Part Three covers saccharification and fermentation methods, enzyme engineering, and the utilization of by-products generated during the pretreatment and fermentation processes. By-products such as xylan, 5-HMF, furfural, phenolic compounds, organic acids, and lignin are discussed in terms of their further conversion and applications. With its extensive coverage of pretreatment techniques, structural analysis, and utilization of by-products, Pretreatment of Lignocellulosic Biomass for Bioenergy Production serves as a valuable resource for researchers and professionals in the field of biofuel production.
