  1. 1. Strategies for the Discovery of Carbohydrate-Active Enzymes from Environmental Bacteria

    Författare :Johan Larsbrink; Vincent Bulone; Harry Brumer; Birte Svensson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CAZyme discovery; xyloglucan; polysaccharide-utilisation locus; microbiota; α-xylosidase; GH31; transglucosidase; human gut; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : The focus of this thesis is a comparative study of approaches in discovery of carbohydrate-active enzymes (CAZymes). CAZymes synthesise, bind to, and degrade all the multitude of carbohydrates found in nature. LÄS MER

  3. 2. Prebiotic Oligosaccharides from Xylan: Heat Pretreatment, Xylanase Hydrolysis, Utilization by Potential Probiotics and Evaluation in a Mouse Study

    Författare :Peter Falck; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; arabinoxylan; xylooligosaccharides; arabinoxylooligosaccharides; Bifidobacterium; Lactobacillus;

    Sammanfattning : Modulation of the gut microbiota with prebiotic oligosaccharides from partially hydrolyzed xylans can be part of the solution for reducing the occurrence of many health problems such as diabetes, cardiovascular disease and cancer. Prebiotics are carbohydrates that selectively stimulate health beneficial bacteria in the colon, restoring homeostasis to the gut environment. LÄS MER

  4. 3. Conversion of xylan into value-added products

    Författare :Reza Faryar; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xylooligosaccharides; biosurfactant; prebiotic; xylan-based film; Lactobacillus brevis;

    Sammanfattning : Today’s high demand on finding sustainable energy sources, replacing petroleum-based products and the needfor healthier food alternatives have forced us to search for natural recoverable resources and explore their manyhidden applications. One such resource is xylan, which has gained much attention as possible raw material forvarious exploitations. LÄS MER

  5. 4. Quinoa Stalks Glucuronoarabinoxylan : Biorefinery,xylooligosaccharides production and potential applications

    Författare :Daniel Salas Veizaga; Bioteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quinoa stalks; Glucuronoarabinoxylan; Xylooligosaccharides; Xylanases; Probiotics;

    Sammanfattning : Quinoa stalks were used as a source of hemicellulose for XOs production and further as prebiotic source for probiotic bacteria. Three methods for extraction of hemicellulose were used, of which alkaline extraction (NaOH [0.5 M]) was the optimum method. LÄS MER
