Fractionation of the polysaccharides obtained from lucerne stems by extraction with dilute alkali furnishes a xylan containing ca. 11% of 4-O-methyl-D-glucuronic acid residues and ca. 1% of rhamnose residues. Partial hydrolysis of the polysaccharide affords 4-O-β-D-xylopyranosyl-D-xylose, the polymer-homologous tri-, tetra-, penta-, and hexa ...

Biodegradation of Hemicelluloses
1990Schulze (1891) gave the name hemicelluloses to those polysaccharides which could be extracted from plants by aqueous alkali. The name seemed appropriate since these polysaccharides were thought to be intermediates in cellulose biosynthesis and were found in close association with cellulose in the cell wall.

Structural Chemistry of the Hemicelluloses
1959Publisher Summary This chapter discusses the structural chemistry of the hemicelluloses. The term “hemicellulose” is applied to those plant cell-wall polysaccharides, which occur in close association with cellulose, especially in lignified tissues, the term often being restricted to substances extracted with alkaline reagents but not with water.

AbstractThe solution properties of the hemicelluloses obtained from Phragmites communis and Arundo donax were investigated. The presented experimental data led to the conclusion that the molecular weight distribution of hemicelluloses depends on the studied product.

Bioconversion of Hemicelluloses
2018Hemicellulose comprises about 25–30% of the lignocellulosic biomass and is the second most abundant polysaccharide after cellulose. These are heterogeneous polymer of pentoses hexoses and sugar acids. Xylans is the major component of hemicellulose and are heteropolysaccharides with homopolymeric backbone chains of 1,4 linked β-d-xylopyranose units.
