  1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  3. 2. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jonna Hellesten; [2023-01-26]
    Nyckelord :;

    Sammanfattning : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

  4. 3. Cloning and expressing the genes encoding Glycerol dehydratase (GDHt) and 1,3-Propanediol dehydrogenase (1,3-PDDH) in E. coli

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Eleni Pechlivani; [2023]
    Nyckelord :1; 3-Propanediol; Glycerol dehydratase; 3-Propanediol dehydrogenase; Glycerol dehydratase reactivase; E. coli; Protein expression; Biotechnology; Technology and Engineering;

    Sammanfattning : The biodiesel sector has witnessed tremendous growth in recent years, leading to a significant increase in glycerol production as a by-product. Addressing the challenge of glycerol valorization is crucial for the sustainability of the biodiesel industry. LÄS MER

  5. 4. Relations between intracellular pH and gamma-aminobutyric acid levels in tea (Camellia sinensis) leaves, after two types of anaerobic treatment

    L3-uppsats, SLU/Dept. Of Plant Biology

    Författare :Mingmin Tao; [2023]
    Nyckelord :tea leaves; intracellular pH; gamma-aminobutyric acid; glutamate; decarboxylase; fluorescent dye;

    Sammanfattning : Tea (Camellia sinensis) is one of the three major non-alcoholic beverages in the world. In Gabaron tea, the levels of γ-aminobutyric acid (GABA) are more than 1.3 mg/g. In the human body, GABA lowers blood pressure and cholesterol levels. LÄS MER

  7. 5. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER
