Lignocellulose can come from biomass such as wheat straw, corn stover, municipal waste, or energy crops. First, these by-products are broken down into a pulp. Enzymes are then added, turning cellulose in the biomass into sugar which can then be …
doi: 10.1002/bit.21238. Authors Alex Berlin 1 , Vera Maximenko, Neil Gilkes, Jack Saddler. Affiliation 1 Forest Products However, the recalcitrance structure of lignocellulose inhibits the binding of enzymes to cellulose, which makes the enzymatic hydrolysis process low efficiency and high cost (Lynd et al., 2008). 2017-06-15 They are known to remarkably improve the hydrolysis of lignocellulose by acting in synergy with other cellulolytic enzymes.

', Journal of Chemical Technology and Biotechnology , vol. 92, no. 4, pp. 868-873. 2012-04-30 The cellulosomic saccharification of lignocellulose is affected by various substrate-related physical and chemical factors, including native (untreated) wood lignin content, the extent of lignin and xylan removal by pretreatment, lignin structure, substrate size, and of course substrate pore surface area or substrate accessibility to cellulose.
2019-08-19 Lignocellulose can come from biomass such as wheat straw, corn stover, municipal waste, or energy crops. First, these by-products are broken down into a pulp.
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
2017-06-15 They are known to remarkably improve the hydrolysis of lignocellulose by acting in synergy with other cellulolytic enzymes. 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 . hemicelluloses hydrolysis is the C 5 sugar. The monosaccharides released upon hemicellulose hydrolysis include a large fraction of pentoses .

353-364. Improvements in enzymatic hydrolysis for production of bioethanol from sustainable biomass are necessary in order to reduce enzyme requirements and the overall processing times. Conventional techniques for pretreatment of lignocelluloses are quite costly, time-consuming, and also require substantial downstream processing. Ultrasound can be effectively used to improve the hydrolysis process by Hydrolysis of lignocellulosic biomass is a crucial step for the production of sugars and biobased platform chemicals. Pretreatment experiments in a semi-continuous plant with diluted sulphuric acid as catalyst were carried out to measure the time-dependent formation of sugars (glucose, xylose, mannose), furfurals, and organic acids (acetic, formic, and levulinic acid) at different hydrolysis 2012-04-04 · The hydrolysis of lignocellulose to glucose is a major bottleneck in cellulosic biofuel production processes .
Pulping and analytical methods of separation are discussed and a consideration is made of the potential products from lignocellulosic sources. The effect of temperature, time and amount of enzyme on hydrolysis of wheat straw lignocellulose remaining after furfural production was studied. The residual substrate was subjected to enzymatic
Conversion of lignocellulosic biomass into sugars is one of the major challenges in producing biofuels and chemicals, because inherent biomass recalcitrance hinders the efficient conversion.

Conversion of lignocellulosic biomass into sugars is one of the major challenges in producing biofuels and chemicals, because inherent biomass recalcitrance hinders the efficient conversion. The most available method in industry is to combine thermochemical pretreatment with enzymatic hydrolysis treatment.
The hydrolysis is usually catalyzed by cellulase enzymes, and the fermentation is carried out by yeasts or bacteria. Sources of lignocellulose materials suitable for conversion into chemical feedstocks are reviewed and the chemical nature of the cellulosic, hemicellulosic and lignin components examined.
