Effect of hemicellulose and lignin on enzymatic hydrolysis of cellulose from brewer`s spent grain
(ELSEVIER SCIENCE INC, 2008)
Enzymatic hydrolysis of brewer`s spent grain in three different forms: original (untreated), pretreated by dilute acid (cellulignin), and pretreated by a sequence of dilute acid and dilute alkali (cellulose pulp), was ...
Influence of different cellulose/hemicellulose/lignin ratios on the thermal degradation behavior: prediction and optimization
(2021-01-01)
Vegetal fibers can be applied in several areas, from the medical field to the development of new advanced materials. They have a complex chemical structure including cellulose, hemicellulose, and lignin. Each component ...
Pseudo-Lignin Content Decreased with Hemicellulose and Lignin Removal, Improving Cellulose Accessibility, and Enzymatic Digestibility
(2020-01-01)
The sugarcane bagasse is a heterogeneous material and needs a pretreatment to breakdown its complex structure to make cellulose accessible to enzyme action. This study aimed to evaluate pseudo-lignin formation, enzymatic ...
Lignin Removal and Cellulose Digestibility Improved by Adding Antioxidants and Surfactants to Organosolv Pretreatment of Sugarcane Bagasse
(2021-01-01)
Annually, tons of sugarcane bagasse are generated in the sugar and alcohol industries. This biomass has great potential in the use of converting cellulose into glucose, an energy currency for various biotechnological ...
Key Factors Affecting the Recalcitrance and Conversion Process of Biomass
(2019-03-15)
Lignocellulosic biomass is one of the most abundant raw materials in the world, and it is mainly composed of carbohydrate polymers (cellulose and hemicellulose) and lignin. Its applications vary from the production of pulp ...
Improved pretreatments applied to the sugarcane bagasse and release of lignin and hemicellulose from the cellulose-enriched fractions by sulfuric acid hydrolysis
(2014)
BACKGROUND A number of pretreatments have been reported in the literature aiming to improve yields with increases in degree of digestibility of the cellulose-enriched fractions, in reducing the process time recalcitrance ...
The enzymatic recalcitrance of internodes of sugar cane hybrids with contrasting lignin contents
(2013-11-01)
The recalcitrance in grasses varies according to cell type and maturation. The origin of the recalcitrance in different regions from sugar cane internodes with varied lignin contents was evaluated. The efficiency of enzymatic ...

Extraction and Characterization of Hemicellulose from Eucalyptus By-product: Assessment of Enzymatic Hydrolysis to Produce Xylooligosaccharides
(2019-01-01)
Eucalyptus wood is the primary source of fibers to produce paper and cellulose in South American countries. The major by-product generated in the cellulose industry is sawdust derived from chip wood production, which is ...
Minimum Lignin and Xylan Removal to Improve Cellulose Accessibility
(2020-09-01)
The lignocellulosic biomass, such as provided by the sugarcane, is an abundant source of raw materials for energy production. Milling and pretreatments can be employed to alter the structure of the materials, remove lignin, ...
