Evaluation of lignin contents in tropical forages using different analytical methods and their correlations with degradation of insoluble fiber
(Animal Feed Science and Technology, 2018)
Reaction rates of lignin and hexenuronic acids with chlorine dioxide, ozone, and a sulfuric acid
(2008-04-01)
The reaction rates of lignin and hexenuronic acids (HexA) with chlorine dioxide, ozone, and sulfuric acid were investigated. In unbleached and oxygen-delignified eucalyptus kraft pulps containing both lignin and HexA, only ...
Evaluation of lignin contents in tropical forages using different analytical methods and their correlations with degradation of insoluble fiber
(Elsevier Science BV, 2011)
We compared the lignin contents of tropical forages by different analytical methods and evaluated their correlations with parameters related to the degradation of neutral detergent fiber (NDF). The lignin content was ...
Lignin surface area influenced by biomass heterogeneity and pretreatment process
(2022-01-01)
Biomass conversion is challenged by the heterogeneity and lignin, a component that acts as a barrier to the enzymatic hydrolysis of polysaccharides. This study evaluated the effect of pretreatments on different fractions ...
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 ...
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 ...
Effect of Dilute Acid Pretreatment on the Sugarcane Leaf for Fermentable Sugars Production
(2022-01-01)
Bioethanol can be produced from lignocellulosic material, however, due to the material recalcitrance, a pretreatment step is needed to improve cellulose accessibility. Dilute acid pretreatment improves the cellulose ...
Obtainment and characterization of nanocellulose from an unwoven industrial textile cotton waste: Effect of acid hydrolysis conditions
(2019-04-01)
Cellulose nanocrystals (CNCs) have a promising application in many advanced products, such as biomedical applications and hydrogels. In this research, industrial cotton waste was treated using alkali and bleaching to ...
Effect of pretreatment and enzymatic hydrolysis on the physical-chemical composition and morphologic structure of sugarcane bagasse and sugarcane straw
(2016-11-01)
The present work aimed to study the effect of the pretreatment of sugarcane bagasse and straw with microwave irradiation in aqueous and acid glycerol solutions on their chemical composition, fiber structure and the efficiency ...
Optimization of FeSO4-assisted sulfuric acid hydrolysis for improved sugar yield from sugarcane bagasse
(2020-10-01)
Sugarcane bagasse (SB) consists of two major sugar polymers (cellulose and hemicelluloses) connected to lignin. Due to the recalcitrant nature of SB, pretreatment is considered a crucial process step before it can be ...
