Xylan of Siphonaceous Green Algae [PDF]
Nature, 1960 COMPARATIVELY little is known at present about the chemical nature of the cell wall constituents of siphonous green algae, especially that of the non-septate groups. Although the cell wall of the algae belonging to Bryopsidaceae, Caulerpaceae and Codiaceae has been stated to consist for the most part of callose (a name given originally to a ...

Outstanding questions on xylan biosynthesis
Plant Science, 2022Xylan is the second most abundant polysaccharide in plant biomass. It is a crucial component of cell wall structure as well as a significant factor contributing to biomass recalcitrance. Xylan consists of a linear chain of β-1,4-linked xylosyl residues that are often substituted with glycosyl side chains, such as glucuronosyl/methylglucuronosyl and ...

Xylan spectroscopy and spectrophotometry
Biotechnology Techniques, 1990An iodine-iodide reagent containing saturated calcium chloride was used for quantitation of larchwood xylan in solution and for improved visualization of xylanase activity on solid media. This spectroscopic methodology is applicable to hemicelluloses from other sources and can differentiate hemicelluloses from other polysaccharides such as amylose ...

Conformational analysis of xylan chains
Carbohydrate Research, 2005The present study provides a theoretical description of the different levels of structural organization that characterize the xylan polysaccharide in its native and hydrophobic lauroyl esterified forms. The goal of this study was to ascertain the role played by the hydroxyl or lauroyl side groups on the conformational flexibility of the xylan chain ...

Xylan and Xylan Derivatives – Basis of Functional Polymers for the Future
2011This review highlights xylan and xylan derivatives. It depicts the occurrence and structural diversity of the biopolymer, followed by a presentation of different ways of isolation from biomass. The determination of characteristics, i.e., molecular weight, interaction with other polysaccharides, thermal behaviour, and the biological activity of xylan ...

Xylan and xylan derivatives—Their performance in bio-based films and effect of glycerol addition
Industrial Crops and Products, 2016Abstract In this work, the successful derivatization of a beechwood xylan (BX) by carboxymethylation and hydroxypropylation was achieved aimed to produce bio-based films. Carboxymethyl xylan (CMX) and hydroxypropyl xylan (HPX) with a substitution degree of 0.3 and 1.1, respectively, as determined by 1H NMR, were synthesised.

The degradation of [({4-O-methyl-}glucurono)arabino]xylans from rice bran, oat spelts, wheat flour, larchwood, and birchwood with two types of endo-(1,4)-β-xylanase (I and III), (1,4)-β-xylosidase, (1,4)-β-d-arabinoxylan arabinofuranohydrolase (AXH), and an acetyl xylan esterase (AE), single and in combinations was investigated.
