Lignocellulosic Materials: Sources and Processing Technologies
Lignocellulosic materials (LCMs) are one of the most promising feedstock for several biotechnological purposes. However, these LCMs are highly complex and present a robust structure of difficult access. For the valorization of each fraction of LCMs, a pre-treatment step is necessary in order to alter and/or remove the surrounding matrix of lignin and hemicellulose and increase the cellulose accessibility. Each pre-treatment has a specific effect on the LCM components and generally more than one pre-treatment step is necessary to obtain the fractions. This chapter primarily covers the definition of LCMs, their composition and varied sources. Subsequently, it is presented their structure, and the advantages and disadvantages of the different pre-treatment methods. Furthermore, a section with examples of successful processing technologies and valorization of each LCM component using different pre-treatment technologies is presented.
