  1. 11. Betydelsen av kolkälla och mikrobiell fysiologisk status för temperaturresponsen (Q10) vid nedbrytning av organiskt material

    L3-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Anders Bergman; [2008]
    Nyckelord :kolkälla;

    Sammanfattning : The increasing threat of climate change has led to a increased need for models to predict future climat. In these models the changes in the soil carbon pools due to changes in microbiel degradation of the organic matter can lead to both positive and negative feedback-effects. LÄS MER

  3. 12. Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning

    L3-uppsats, SLU/Dept. of Biometry and Engineering

    Författare :Jenny Leonardsson; Emma Östensson; [2005]
    Nyckelord :kompostering; avfall;

    Sammanfattning : Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. LÄS MER

  4. 13. Phytoremediation of a highly creosote-contaminated soil by means of Salix viminalis

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Karin Önneby; [2005]
    Nyckelord :wood impregnation site; phytoremediation; salix viminalis; PAH degredation; phenanthrene; anthracene; fluoranthene; pyrene; benzo[a]pyrene; GC-MS; bacterial strains; extracted and cultivable bacteria; bulk soil; rhizosphere soil;

    Sammanfattning : The aims of this study were to investigate whether Salix viminalis could grow in a highly creosote contaminated soil and, if so, whether the introduction of the plant enhanced the dissipation of polycyclic aromatic hydrocarbons (PAHs). The purpose was also to examine whether inoculation of two different bacterial strains further enhanced the decrease of the contaminant. LÄS MER
