Alterations of the degree of xylan acetylation inArabidopsisxylan mutants [PDF]

open access: yesPlant Signaling & Behavior, 2014
Xylan is the second most abundant polysaccharide in secondary walls of dicot plants and one of its structural features is the high degree of acetylation of xylosyl residues. In Arabidopsis, about 60% of xylosyl residues in xylan are acetylated and the biochemical mechanisms controlling xylan acetylation are largely unknown.

Caracterização das O-acetil-(4-O-metilglicurono)xilanas isoladas da madeira de Eucalyptus urograndis Characterization of O-acetil-(4-O-methylglucurono)xylans from Eucalyptus urograndis

open access: yesQuímica Nova, 2008
The O-acetyl-4-O-methyl-(glucurono)xylans were isolated from E. urograndis by extraction with dimethyl sulfoxide, analysed for monosaccharide composition and structurally characterized by NMR spectroscopy. These xylans contained one 4-O-methyl-glucuronic

Xylan extraction from pretreated sugarcane bagasse using alkaline and enzymatic approaches

open access: yesBiotechnology for Biofuels, 2017
Background New biorefinery concepts are necessary to drive industrial use of lignocellulose biomass components. Xylan recovery before enzymatic hydrolysis of the glucan component is a way to add value to the hemicellulose fraction, which can be used in ...

Physicochemical and rheological properties of agarose/xylans composite hydrogel materials [PDF]

open access: yes, 2013
Agarose (AG)=Xylans [beech (BX) and oat spelt (OSX)] composite hydrogels were prepared by effortless mixing method, using water as solvent. The gelling behavior of the composite hydrogels was investigated by a rheometer fitted with a temperature control ...

Designer biomass for next-generation biorefineries: leveraging recent insights into xylan structure and biosynthesis

open access: yesBiotechnology for Biofuels, 2017
Xylans are the most abundant noncellulosic polysaccharides in lignified secondary cell walls of woody dicots and in both primary and secondary cell walls of grasses.

Two novel GH11 endo-xylanases from Myceliophthora thermophila C1 act differently toward soluble and insoluble xylans [PDF]

open access: yes, 2013
Two novel GH11 endo-xylanases from Myceliophthora thermophila C1 (C1), Xyl7 and Xyl8, were purified and the influence of solubility and molecular structure of various xylans on their efficiency was investigated.

Developing pericarp of maize: a model to study arabinoxylan synthesis and feruloylation

open access: yesFrontiers in Plant Science, 2016
Cell walls are comprised of networks of entangled polymers that differ considerably between species, tissues and developmental stages. The cell walls of grasses, a family that encompasses major crops, contain specific polysaccharide structures such as ...

Accessory enzymes involved in the hydrolysis of xylans [PDF]

open access: yes, 1991
Xylans are heteropolysaccharides which are depolymerized by β-1,4-D-endoxylanases. Due to the abundance and variety of substituents in native xylans, different accessory enzymes are also needed for the total hydrolysis of xylan.
