Our detailed analysis of the muci10 mutants demonstrates that mucilage contains highly branched galactoglucomannan (GGM) rather than unbranched glucomannan. MUCI10 likely decorates glucomannan, synthesized by CELLULOSE SYNTHASE-LIKE A2, with galactose residues in vivo.

JSON. Publications.

This also resulted in a separation degree, which was higher compared with the hydrophobic membrane, thus yielding a higher galactoglucomannan (GGM) purity. 2D HSQC NMR results show that no major structural differences were present in the hydrophilic and hydrophobic retentates.

Production of the GGMO substrate involves wood chips, water, and pressure, but does not use Acid hydrolysis of O-acetyl-galactoglucomannan (GGM), the main non-cellulosic polysaccharide in coniferous wood, was studied at 90 °C in the pH range of Jun 1, 2015 Abstract.

GGM can be hydrolyzed into fermentable sugars, or used as a polymer in films, gels, and food additives. In this work, the usability of modified O-acetyl galactoglucomannan (GGM) for modification of NFC surface properties was studied. Four GGM-block-structured, amphiphilic derivatives were synthesized using either fatty acids or polydimethylsiloxane as hydrophobic tails.

Galactoglucomannan is a water-soluble hemicellulose, consisting of galactose, glucose and mannose.Many softwood species, e.g. Norway spruce are rich of galactoglucomannans and can contain it up to 10–20%.

Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener.

Galactoglucomannan is a water-soluble hemicellulose, consisting of galactose, glucose and mannose. Many softwood species, e.g. Norway spruce are rich of galactoglucomannans and can contain it up to 10–20%. Galactoglucomannan, which is present in greater amounts, is an essentially linear molecule. It has a backbone chain made up of d-glucopyr-anose and d-mannopyranose residues which are joined together by β(1 → 4)-linkages. Galactoglucomannan (GGM) is the main hemicellulose in Norway Spruce (Picea abies), the most common raw material used in the thermochemical mills in Scandinavia.
