  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

  4. 3. The potential to use rhizobacteria within agricultural innovations instead of chemical inputs : taking quality and quantity of the crop into consideration

    Kandidat-uppsats, SLU/Dept. Of Plant Biology

    Författare :Ida Quisth; Isabella Ulfsparre; [2024]
    Nyckelord :Biocontrol; Biofertilizer; Biopesticide; Biostimulant; Plant growth promoting rhizobacteria; PGPR; Quality; Rhizosphere Microbiome; Yield;

    Sammanfattning : Plant growth promoting rhizobacteria (PGPR) are soil bacteria that occur naturally, colonize the roots of plants and can promote plant growth. PGPR isolated and used as inoculum to seed or plants is mostly marketed as a growth stimulant because it facilitates registration and reduces costs, even though PGPR may also serve as biocontrol products.

  5. 4. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ivana Pia Saric Söderholm; Erik Readwin; [2023]
    Nyckelord :Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

    Sammanfattning : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

  7. 5. Evaluation of liver and fur copper concentrations in dairy cows : in relation to dietary intake of copper and molybdenum

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

    Författare :Ida Hansen; [2023]
    Nyckelord :copper; copper status; dairy cow; fur; liver; molybdenum; ruminant;

    Sammanfattning : Koppar (Cu) har en avgörande roll i flera viktiga metaboliska funktioner och är en essentiell mineral för idisslare. Kopparbrist kan resultera i ett flertal problem som påverkar djurets hälsa och produktion, men även överutfodring av Cu kan resultera i allvarliga kliniska symptom på grund av ackumulering av Cu i levern.
