found that hemicellulose and lignin in dairy manure, similar to their role in other lignocellulosic material, were major resistive factors to enzymatic hydrolysis and that the removal of either of them, or for best performance, both of them, improved the enzymatic hydrolysis of manure cellulose. Th...
Pulp obtained from the processing of sugar beet at a local factory is mixed with molasses and sold as cattle food. However, the value of the pulp would be increased considerably if its constituent cellulose and hemicellulose fractions could be converted to fermentable sugars. To this end we are...
liquids were used for comparison. Palm stem as a lingocellulosic material was provided by PT Perkebunan Nusantara VIII, which its compositions were shown in Table 1. TABLE 1. COMPOSITION OF PALM STEM Component % a Lignin 23.01 Cellulose 42.63 Hemicellulose 18.58 Other component 12.27 a based on ...
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...
In recent years, treatment of lignocellulosic biomass with dilute sulfuric acid has been primarily used as a means of hemicellulose hydrolysis and pretreatment for enzymatic hydrolysis of cellulose. A significant advancement has also been made in the area of dilute acid hydrolysis of cellulose. An ove...
Sulfonated hierarchical H-USY zeolite for efficient hydrolysis of hemicellulose/cellulose The acidity of the hierarchical H-USY was remarkably improved. Sulfonated hierarchical H-USY zeolite was efficient for the hydrolysis of hemicellulose and ... L Zhou,Z Liu,M Shi,... - 《Carbohydrate Polymers》...

Hemicelluloses are heteropolymers present along with cellulose in all terrestrial plant cell walls. Lignocellulosic biomass consists of 20–30% hemicellulose which can be effectively valorized for value-added products and biofuels. Xylan, arabinoxylan, glucuronoxylan, xyloglucan, mannan, galactan, arabinog...
