  2. 1. Galactoglucomannan-degrading enzymes from Aspergillus niger

    Author : Pia Ademark; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; Aspergillus niger; beta-mannosidase; alpha-galactosidase; purification; hydrolysis; cloning; galactoglucomannan; expression; Biochemistry; Metabolism; Biokemi;

    Abstract : Galactoglucomannan and galactomannan are among the most abundant plant polysaccharides in nature. The central enzymes involved in their degradation, i.e., endo-1,4-beta-mannanase (beta-mannanase, EC 3. READ MORE

  4. 2. Chemical Pathways for Galactoglucomannan-based Materials

    Author : Jens Voepel; Ann-Christine Albertsson; Ulrica Edlund; Søren Hvilsted; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polysaccharides; hemicelluloses; galactoglucomannan; renewable; chemical modification; hydrogels; swelling; crosslinking; release; SET-LRP; living polymerization; grafting; hybrid materials; Polymer chemistry; Polymerkemi;

    Abstract : Polysaccharides are an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Due to their natural diversity they can be found in many special applications, e.g. in the biomedical sector and are the major renewable resource for materials of many kinds. READ MORE

  5. 3. Galactoglucomannan recovery from softwood spent sulfite liquor: Challenges, process design and techno-economic evaluations

    Author : Basel Al-Rudainy; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galactoglucomannan; Lignin; Lignosulfonates; Lignin-carbohydrate-complexes; Membrane filtration; Dead-end filtration; Precipitation; Adsorption;

    Abstract : In the production of pulp and paper, water-soluble components, such as hemicellulose, monosaccharides, and lignin, are released and accumulate in the process water. The process water is usually concentrated and incinerated for heat generation and the recovery of pulping chemicals, such as in the Kraft and sulfite processes. READ MORE

  6. 4. Hemicellulose as barrier material

    Author : Hartman Jonas; Ann-Christine Albertsson; Gunnar Henriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemicellulose; galactoglucomannan; plasma surface treatment; vaporphase grafting; benzylation; contact angle; oxygen permeability; solution casting; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Polysaccharides constitute an important source of raw materials for the packaging industry today. Polysaccharides have good natural barrier properties which are necessary for packaging films. Cellulose is the forerunner among renewable polymers for such applications. Hemicelluloses represent a new interesting breed of barrier materials. READ MORE

  7. 5. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis

    Author : Alexandra Andersson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; Physical chemistry; Fysikalisk kemi; enzymology; hydrogels; Plant biochemistry; Växtbiokemi; Proteins; a-galactosidase; b-mannanase; hemicellulase; corn fibre; barley husks; spruce; size-exclusion chromatography; arabinoxylan; microwave irradiation; steam pretreatment; membrane filtration; hemicellulose; galactoglucomannan;

    Abstract : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. READ MORE
