  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

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE

  3. 2. Allelopatisk förmåga hos Cannabis sativa L. (Hampa) och dess potential som biologisk bekämpning av ogräs

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Rasmus Lundell; [2022]
    Keywords : Cannabis sativa; allelopati; biologisk kontroll; fytoremediering; ogräs; sekundärmetaboliter;

    Abstract : Sedan människan började kultivera växter har ogräsbekämpning varit en viktig del av odlingen. Under det senaste halvseklet har användningen av kemiska bekämpningsmedel blivit allt vanligare men i takt med att vi sett risker har lagstiftarna tvingats reglera användningen samtidigt som odlare söker alternativ.

  5. 4. The effectivity of vacuum impregnation with glycerol and secondary metabolites on electroporated arugula leaves to improve freezing stability.

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Oscar de Kuijer; [2021]
    Keywords : Pulsed electric field PEF; Arugula; Electroporation; Secondary metabolites; Glycerol; Food engineering; Livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. READ MORE

  6. 5. Effects of Vacuum Impregnation with Various Substances in Combination with Pulsed Electric Field to Improve the Freezing Tolerance of Arugula Leaves

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : George Lukhava; [2021]

    Abstract : As of 2020 an estimated number of 821 million people across the world are undernourished and that figure is expected to grow by 2 billion before the end of 2050 (United Nations Sustainable Development 2020). Despite this, every year over 1/3 of food produced globally is disposed of without consumption (Global Panel on Agriculture and Food Systems for Nutrition 2018), and the actual number might be much higher.
