  1. 1. Anaerobic cellulose degrading bacteria isolated from biogas plants

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Caroline Sjöberg; [2023]
    Nyckelord :anaerobic bacteria; biogas; cellulose; cellobiose; VFA; enzyme activity; TRFLP;

    Sammanfattning : Two cellulose degrading bacteria, named BCISO-4 and DC1-18-4, were isolated from samples retrieved from two large scale biogas-plants. In order to investigate and determine information regarding their growth preferences multiple tests were performed. LÄS MER

  3. 2. Cultivating oleaginous yeast on spent mushroom substrate and logging residues hydrolysate : an assessment of yeast growth on side product substrates from the food, agriculture, and forestry industry

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Robin Lukic; [2023]
    Nyckelord :Lignocellulose; side products; oleaginous yeast; yeast oil; microtiter plate system; redox indicator; yeast growth; spent mushroom substrate hydrolysate; logging residues hydrolysate;

    Sammanfattning : There is an interest in finding alternatives to vegetable oils because of negative environmental impact. Many green sectors generate an abundant amount of side products that are inedible and consist in large of lignocellulose rich materials. LÄS MER

  4. 3. Impact of pulp chemical composition and fiber morphology on hygroexpansion and strength properties of kraftliner

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Serdar Unal; [2023]
    Nyckelord :Chemical Engineering; Hygroexpansion; Pulp; Kraftliner; Tensile strength; Iso-brightness; Chemistry;

    Sammanfattning : Kraftliner is the unbleached pulp used in the outermost layer of corrugated cardboard. Like other types of paper, it is produced from wood chips as a raw material. Kraftliner is known for its high tensile strength, tear resistance, compressive strength, etc., making it suitable for packaging material for heavy objects. LÄS MER

  5. 4. Production, Purification, and Characterization of wood substrates and Galactose oxidase enzyme

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Rakhesh Pongalikonnar Ranganathan; [2023]
    Nyckelord :Peracetic acid treatment; Galactose oxidase; Pichia pastoris; Biomass recalcitrance; Enzymatic upgrading; Perättiksyrabehandling; Galaktosoxidas; Pichia pastoris; Motsträvighet i biomassa; Enzymatisk uppgradering;

    Sammanfattning : Trä är den bästa förnyelsebara källan för att producera många produkter på grund av dess biokompatibla och biologiskt nedbrytbara natur. Träets biomassa har en motstridig natur mot enzymatisk uppgradering. LÄS MER

  7. 5. Fibre content in moose (Alces alces) faeces : a comparison between free-ranging and captive moose in Sweden

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Ada Trapp; [2022]
    Nyckelord :diarrhoea; zoo; browser; ruminant; Alces alces;

    Sammanfattning : Animals have evolved adaptations to survive and reproduce in certain environments. Based on these adaptations, different feeding types can be identified among ruminants from the continuum of browsers to grazers. Browsers are assumed to digest forage rich in soluble cell contents, while grazers are more equipped to digest cellulose. LÄS MER
