  1. 1. Valorisation of cereal by-products: a biorefinery approach

    Författare :Reskandi C. Rudjito; Franscisco Vilaplana; Amparo Jimenez-Quero; Mirjam Kabel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cereal by-products; arabinoxylan; ferulic acid; subcritical water extraction; enzymatic treatment; xylanases; prebiotics; Jordbruksbiprodukter; arabinoxylan; ferulsyra; subkritisk vattenextraktion; enzymatisk behandling; xylanaser; prebiotika; Bioteknologi; Biotechnology;

    Sammanfattning : Cereal by-products are abundant streams of underutilised biomass that have the potential be valorised into various industrial products by means of environmentally friendly processes. In this study, an integrated bioprocess combining subcritical water extraction (SWE) and enzymatic treatment (ET) was proposed to effectively extract arabinoxylans (AX) from cereal by-products.

  3. 2. 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

  4. 3. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

    Författare :Zubaida Gulshan Kazi; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycoside hydrolase; transglucosylation; alkyl glycoside; cyclodextrin glucanotransferase; Rhodothermus marinus; xylanases; hydrolysis; beta-glucosidases;

    Sammanfattning : Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. LÄS MER

  5. 4. RECOMBINANT PEROXIDASES AND XYLANASES: I. Cloning and production of a peroxidase from horseradish II. Characterisation of functional domains of thermostable xylanases from Rhodothermus marinus

    Författare :Eva Bartonek Roxå; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous cellulose; xylan; CBD; carbohydrate binding domains; insect cells; Baculovirus; catalytically active; recombinant horseradish peroxidase; HRP-n; PASC; beta-glucan; Biotechnology; Bioteknik;

    Sammanfattning : Part I: Plant peroxidases are useful in many areas of application e.g. as tracer enzymes for clinical applications and in biosensors as well as for industrial purposes like in waste water treatment and bleaching processes. A gene encoding a new, neutral horseradish peroxidase isoenzyme, HRP-n, was isolated. LÄS MER
