  1. 11. Bacterial and fungal responses to drying and rewetting using bronopol or cycloheximide as inhibitors

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Simon Lin; [2019]
    Nyckelord :Drying-rewetting; respiration; growth rate; growth response; Earth and Environmental Sciences; Biology and Life Sciences;

    Sammanfattning : Microbial decomposers breakdown soil organic matter, releasing carbon dioxide (CO2) to the atmosphere. This release of CO2 could therefore contribute to future climate change. LÄS MER

  3. 12. The effect of ration forage proportions on the microbial ecology of the Rumen

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

    Författare :Rasmus Vihermäki; [2019]
    Nyckelord :ekologi; grovfoder; kraftfoder; VFA; acidos; idisslare;

    Sammanfattning : Grovfoder utgör en stor del av kons foderintag och dess struktur är viktig för kons hälsa. En foderstat som till största delen innehåller kraftfoder främjar tillväxten av exempelvis Lactobacilli och Streptococcus bovis (S.bovis) som i sin tur producerar laktat. Laktat sänker pH i vommen och kan leda till vomacidos. LÄS MER

  4. 13. Probiotics : how does it affect our health?

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Julia Abrahamsson; [2018]
    Nyckelord :probiotics; microbiota; intestinal microbiota; probiotic mechanism of action; irritable bowel syndrome; IBS; microbial ecology; gut microbiota;

    Sammanfattning : The human body consists of about 10 times as many bacteria as our own body cells. Only the gastrointestinal tract can hold up to 400 different bacterial species, where the majority of the bacteria are concentrated to the large intestines. LÄS MER

  5. 14. Rhizosphere Priming and Methane Oxidation in Agricultural Soil - Effect of Land Use on Atmospheric Concentrations of CO2 and CH4 and Climate Change

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Esben Øster Mortensen; [2017]
    Nyckelord :The Priming Effect; Rhizosphere; Methane Oxidation; Land Use; Agriculture; Soil Ecology; Microorganisms; Climate Change; Atmospheric concentrations of CO2 and CH4.; Earth and Environmental Sciences; Biology and Life Sciences; Agriculture and Food Sciences;

    Sammanfattning : Rhizosphere interactions have high influence on the fluxes of carbon to and from terrestrial ecosystems. One very important part of the rhizosphere interactions is the rhizosphere priming effect (RPE) which is defined as changes in the decomposition rate of soil organic matter (SOM) in response to labile organic carbon input from plant roots.

  7. 15. Structural and Functional Changes in a Lake Bacterial Community Exposed to Multiple Stress Regimes

    Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

    Författare :Philipp Siegel; [2015]
    Nyckelord :bacterial community; microbial community; resilience; resistance; microbiology; environmental change; limnology; Sweden; Ekoln; bacterial productivity; enzyme activity; DOM; spectrometry; T-RFLP; NMDS; environmental fitting; microbial ecology;

    Sammanfattning : Bacterial community resilience and resistance may play an important role in a world affected by climate change and increasing environmental disturbances. In this study we examined the resilience of a bacterial lake community from Lake Ekoln, Sweden, under increased environmental stress. LÄS MER
