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

    Författare :Martin J. Baumann; Tuula T. Teeri; Harry Brumer; Vincent Eijsink; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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.

  5. 4. Strategies for cellulose fiber modification

    Författare :Per Persson; KTH; []
    Nyckelord :Candida antarctica lipase B; cationic catalysis; cellulose-binding module; dendrimer; enzymatic polymerization; fiber modification; silica-cast replica; sol-gel mineralization; organocatalysis; xyloglucan endotransglycosylase;

    Sammanfattning : This thesis describes strategies for and examples ofcellulose fiber modification.The ability of an engineered biocatalyst, acellulose-binding module fused to theCandida antarcticalipase B, to catalyze ring-openingpolymerization of e-caprolactone in close proximity tocellulose fiber surfaces was explored.

  7. 5. Surface modification of cellulose materials : from wood pulps to artificial blood vessels

    Författare :Lage Ahrenstedt; Harry Brumer; Lars Wågberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : This thesis describes the improvement of two radically different cellulose materials, paper and artificial blood vessels, constructed from two diverse cellulose sources, wood pulp and Acetobacter xylinum. The improvement of both materials was possible due to the natural affinity of the hemicellulose xyloglucan for cellulose. LÄS MER
