Various hemicellulose fractions were extracted from wheat straw holocellulose (extractive and pectin free) by successive treatments with cold and hot water, 0.5%, 1.0%, and 2.0% potassium hydroxide and were recovered by precipitation with alcohol. Approximately 25% of the holocellulose material was removed, one half being in the hot water soluble ...

Conversion of hemicellulose carbohydrates
1981Hemicellulose can be converted to a variety of useful products. There are two approaches to hemicellulose bioconversion; hemicellulose can be directly converted, or the hemicellulose-derived carbohydrates can be used as the substrate. The major problem in the bioconversion of hemicellulose carbohydrates is that suitable organisms which convert pentoses

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.

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.

Publisher Summary This chapter focuses on wood hemicelluloses. The major hemicelluloses of wood, structural details, such as the degree of branching of xylans and glucomannans, the distribution of their various side-chains, and the state of the uronic acid groups in the native xylans remain to be established.

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.
