Followingpretreatment,enzymatic hydrolysisdepolymerizes cellulose andhemicellulosesto form monomeric sugars prior to fermentation. Cellulose mainly contains glucan, which is hydrolyzed to glucose, whilehemicellulosecontains several polymeric sugars composed ofpentoses(xylose and arabinose) andhexoses(glucose, manno...
Hydrolysis of carbohydrates is also of great industrial importance, typically in the field of production processing of cellulosic biomass (cellulosic biomass is composed of cellulose, hemicellulose, and lignin), such as agricultural plant wastes (corn stover, cereal straws, and sugarcane bagasse), plant...
Hemicellulose is often credited with being one of the important physical barriers to enzymatic hydrolysis of cellulose, and acts by blocking enzyme access to the cellulose surface. In addition, our recent research has suggested that hemicelluloses, particularly in the form of xylan and its oligomers...
The optimum conditions gave a yield of 38% total fermentable sugars. The kinetics of dilute acid hydrolysis of cellulose and hemicelluloses (polysaccharides) were simulated using four pseudo-kinetic models. The reaction rate constants were calculated in each case.Sidiras...
The rice milling pro- cess generates approximately 28% of RH as a by-product that is mostly used as a solid fuel. Previous studies reported that RH contains lignocellulosic material that consists of cellulose and hemicellulose at 36% and 29%, respectively1. The hemicellulose structure of RH...

7b) and lipopeptide did not release CBHs from holocellulose as well. These results suggested that lipopeptide hardly influenced the binding of CBHs to cellulose and hemicellulose. When lignin was used as the substrate, the affinity of 45818-WT to lignin was stronger than that of 45818-Core. For...
The biomass substrate for use as a source of cellulose and hemicellulose for hydrolysis using the present enzyme compositions and methods can be, e.g., herbaceous material, agricultural residues, forestry residues, municipal solid waste, waste paper, and pulp and paper residues, and the like. Com...
