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

    Författare :Alexandra Andersson; Biokemi och Strukturbiologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Effects of Molecular Architecture of Xylans on Material Properties

    Författare :Maria Gröndahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Xylans are among the most abundant polymers on earth. Nature has created xylans with different molecular structures in different plant species. This molecular architecture is not a coincidence but is tailored to create a particular desirable functionality. LÄS MER

  4. 3. Optically pure lactic acid production from lignocellulosic biomass

    Författare :Joana Coutinho Campos; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lactic acid; enantiomers; softwood; waste viscose; fermentation; Pediococcus acidilactici;

    Sammanfattning : Lactic acid is a platform chemical that can be used for many applications. More recently, optically pure lactic acid—L- or D-lactic acid enantiomers—have been used for the polymerisation to poly-lactic acid (PLA). LÄS MER

  5. 4. 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.
