According to Mansfield et al. [10], the lignocellulosic materials
in the original form are relatively resistant to microbial
attack, but the hemicellulose and lignin removal causes extensive
changes in the structure and accessibility of cellulose that
becomes more accessible and more open to swelling on contact
with cellulases. Therefore, the enzymatic hydrolysis of lignocellulosic
materials is low prior to the hemicellulose and lignin
removal
