  2. 1. Xyloglucan-active enzymes : properties, structures and applications

    Author : Martin J. Baumann; Tuula T. Teeri; Harry Brumer; Vincent Eijsink; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xyloglucan; xyloglucan endo-transglycosylase hydrolase; xyloglucan endo-hydrolase; xyloglucan endo-transglycosylase; XET; xyloglucan oligosaccharides; synthesis; carbohydrate; cellulose; crystal structure; fiber; surface modification; Populus tremula x Populus tremuloides; Hybrid aspen; nasturtium; NXG; Biochemistry; Biokemi;

    Abstract : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. READ MORE

  4. 2. Design and synthesis of xyloglucan oligosaccharides : structure-function studies and application of xyloglucan endotransglycosylase PttXET16A

    Author : Martin J. Baumann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; xyloglucan oligosaccharides; xyloglucan endotransglycosylase; XET; crystal structure; fiber surface modification; Populus tremula x Populus tremuloides; Hybrid aspen;

    Abstract : Primary cell walls are a composite of cellulose microfibrilsand hemicelluloses. Xyloglucan is the principal hemicelluloseof primary cell walls of dicotyledons. Xyloglucanendotransglycosylases (XETs) cleave and religate xyloglucanpolymers in plant cell walls. READ MORE

    Abstract : Xyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.

  6. 4. Plant and microbial xyloglucanases: Function, Structure and Phylogeny

    Author : Jens Eklöf; Harry Brumer; Harry Gilbert; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; xyloglucan; xyloglucanases; XTH; XET; XEH; endoglucanases; EG16; Molecular biology; Molekylärbiologi;

    Abstract : In this thesis, enzymes acting on the primary cell wall hemicellulose xyloglucan are studied.  Xyloglucans are ubiquitous in land plants which make them an important polysaccharide to utilise for microbes and a potentially interesting raw material for various industries. READ MORE

  7. 5. Xyloglucan-based polymers and nanocomposites – modification, properties and barrier film applications

    Author : Joby Kochumalayil Jose; Lars Berglund; José M. Kenny; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xyloglucan; packaging; oxygen barrier; nanocomposites;

    Abstract : Biopolymers from renewable resources are of interest for packaging applications as an alternative to conventional petroleum-based polymers. One of the major application areas for biopolymers is food packaging, where a candidate polymer should meet critical requirements such as mechanical and oxygen barrier performance, also in humid conditions.
