Characteristics of the Water- and Alkali-Soluble Hemicelluloses Fractionated by Sequential Acidification and Graded-Ethanol from Sweet Maize Stems

Molecules, 2019
Sweet maize stems were treated with hot water and potassium hydroxide to fractionate hemicellulosic polymers. The results showed that the water-soluble hemicelluloses were mainly composed of glucose (27.83%), xylose (27.32%), and galactose (16.81%).

Effect of integrated treatment on enhancing the enzymatic hydrolysis of cocksfoot grass and the structural characteristics of co-produced hemicelluloses

Biotechnology for Biofuels, 2021
Background Cocksfoot grass (Dactylis glomerata L.) with high biomass yield and rich cellulose can be used to produce bioethanol as fuel additive. In view of this, ultrasonic and hydrothermal pretreatments followed by successive alkali extractions were ...

Xylo-oligosaccharides preparation through acid hydrolysis of hemicelluloses isolated from press-lye

Grain & Oil Science and Technology, 2019
The preparation of xylo-oligosaccharides (XOSs) through hydrolysis of hemicelluloses was studied. The hemicelluloses were isolated from the press lye discharged in the production of viscose, which contained about 30% xylan. Then, a factorial experimental

Lignin-Rich PHWE Hemicellulose Extracts Responsible for Extended Emulsion Stabilization

Frontiers in Chemistry, 2019
Wood hemicelluloses have an excellent capacity to form and stabilize oil-in-water emulsions. Galactoglucomannans (GGM) from spruce and glucuronoxylans (GX) from birch provide multifunctional protection against physical breakdown and lipid oxidation in ...

Influence of fertilisation type and harvest date on lignin content and structural carbohydrates in meadow plants [PDF]

Journal of Water and Land Development
The nutritional value of green forage is a result of various pratotechnical practices, including fertilisation and harvest timing. Additionally, individual plant species present in natural grasslands may respond differently to those practices.
