Xylan and xylan derivatives – biopolymers with valuable properties, 1. Naturally occurring xylans structures, isolation procedures and properties [PDF]
Macromolecular Rapid Communications, 2000 The availability of xylan-type polysaccharides, representing an immense resource of biopolymers for practical application, is summarized. Xylans constitute 25–35% of the dry biomass of woody tissues of dicots and lignified tissues of monocots and occur up to 50% in some tissues of cereal grains.

The Xylan of Rhodymenia palmata
Nature, 1950Barry and Dillon1 reported the isolation from the red seaweed Rhodymenia palmata of a polysaccharide which gave D-xylose on hydrolysis. Our special interest in xylans2 has led us to investigate this substance more fully as part of the research programme of the Scottish Seaweed Research Association.

Functionalized xylans in the production of xylan-coated paper laminates
Reactive and Functional Polymers, 2017Abstract Two functionalized xylans, namely a carboxymethyl xylan (CMX) and a 2-dodecenyl succinic anhydride-modified xylan (X-2-DSA) were, i) synthesized from beechwood xylan (BX) and characterized for their structural properties, thermal behaviour and molar mass and, ii) used in the production of paper/xylan laminates for food packaging.

Catalysis Today, 2016
Abstract The public interest in usage of lignocellulosic biomass as a renewable resource has grown strongly during the last decade. Hemicelluloses are the second most abundant constituents of wood biomass, but have yet received less attention, compared to cellulose.

Carbohydrate Polymers, 2011
Xylan was 2-hydroxypropylsulfonated and/or 2-hydroxypropylquaternized for film application. All the products were water soluble with molar masses of the derivatives between Mn of 3.8 and 948.9 kg/mol with polydispersity index D from 1.7 to 26.8. At the range from 100 to 250 ?m of thickness the material developed reproducible mechanical properties. When

Enzymatic Hydrolysis of Xylan [PDF]
Nature, 1953 A PREVIOUS investigation1 has shown that enzymes from Chœtomium globosum are able to hydrolyse wheat straw xylan to xylose with the formation of a series of intermediates, designated a,b,c, … g, which appear on paper-chromatograms with regularly decreasing RF-values, and which are believed to be oligosaccharides with regularly increasing xylose units ...

Xylan-degrading activity in yeasts: Growth on xylose, xylan and hemicelluloses
Folia Microbiologica, 1978The ability to grow in liquid media with D-xylose, xylan from decidous trees, and hemicelluloses from conifers was tested in 95 strains of 35 genera of yeasts and yeast-like organisms. Of 54 strains thriving on xylose, only 13 (genera Aureobasidium, Cryptococcus and Trichosporon) utilized xylan and hemicelluloses as growth substrates.

Role of Hydrogen Bonding in the Interaction between a Xylan Binding Module and Xylan
Biochemistry, 2001NMR studies of the internal family 2b carbohydrate binding module (CBM2b-1) of Cellulomonas fimi xylanase 11A have identified six polar residues and two aromatic residues that interact with its target ligand, xylan. To investigate the importance of the various interactions, free energy and enthalpy changes have been measured for the binding of xylan to

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 ...
