The most available method in industry is to combine thermochemical pretreatment with enzymatic hydrolysis treatment. Reduction in the adsorption of cellulase onto lignin has been thought to be the common reason for the improvement of enzymatic hydrolysis of lignocellulose (EHLC) by a nonionic surfactant (NIS). Few research studies have focused on the relationship between lignocellulosic features and NIS for improving EHLC. Enzyme derived from Trichoderma reesei have been utilised for lignocellulosic biomass hydrolysis. However, such enzymes are unable to efficiently hydrolyse hemicelluloses and lignin components in LIGNOCELLULOSE HYDROLYSIS 309 substance, slightly modified as the hemicellulose is removed, is termed lignin. Alternatively, lignin can be removed in a form that is considerably modified from the natural polymer by treatment with chlorine and leaching with sodium hydroxide (or by using sodium chlorite). Sources of lignocellulose materials suitable for conversion into chemical feedstocks are reviewed and the chemical nature of the cellulosic, hemicellulosic and lignin components examined.

Sources of lignocellulose materials suitable for conversion into chemical feedstocks are reviewed and the chemical nature of the cellulosic, hemicellulosic and lignin components examined. Pulping and analytical methods of separation are discussed and a consideration is made of the potential products from lignocellulosic sources. The acid hydrolysis of lignocellulosic material (LM) is one of the most widely studied and important subprocess in the LM biorefinery.

lignocellulose pre-treatment is among the most costly steps and has a major inﬂuence on the costs of both prior operation (e.g., lignocellulose particle size reduction) and subsequent operations (e.g., enzymatic hydrolysis and fermentation) (Wooley et al., 1999; Wyman et al., 2005b). A number of lignocellulose pre-treatment technologies are lignocellulose for enzymatic hydrolysis, or as the actual method of hydrolysis to ferment-able sugars.

Especially the cellulose‐active lytic polysaccharide monooxygenases (LPMOs; CAZy: AA9) attracted attention due to their ability to directly oxidize crystalline substrate surfaces, which extremely enhances the overall degradability of cellulose 41 - 43 .

Biofuels produced from various lignocellulosic materials, such as wood, agricultural, or forest residues, have the potential to be a valuable substitute for, or complement to, gasoline. Many physicochemical structural and compositional factors hinder the hydrolysis of cellulose present in biomass to sugars and other organic compounds that can later be converted to fuels. The goal of LIGNOCELLULOSE HYDROLYSIS 309 substance, slightly modified as the hemicellulose is removed, is termed lignin. Alternatively, lignin can be removed in a form that is considerably modified from the natural polymer by treatment with chlorine and leaching with sodium hydroxide (or by using sodium chlorite).
