  1. 1. Bacterial use of allochthonous organic carbon for respiration and growth in boreal freshwater systems

    Författare :Martin Berggren; Mats Jansson; Michael L. Pace; Umeå universitet; []
    Nyckelord :lakes; streams; boreal; bacterial respiration; bacterial production; bacterial growth efficiency; allochthonous organic carbon; low molecular weight compounds; naturgeografi; Physical Geography;

    Sammanfattning : Aquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere.

  3. 2. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

    Författare :Stephanie Reischke; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

    Sammanfattning : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. LÄS MER

  4. 3. Nutrient Limitation of Bacterial Growth in Soil

    Författare :Fredrik Demoling; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; Fertilization; Bacteria; Soil; Fungi; Thymidine or Leucine incorporation; Growth limitation; Phosphorus; Nitrogen; Carbon;

    Sammanfattning : Lack of carbon has been assumed to be the most common limiting factor for bacterial growth in soil, although there are reports of limitation by nitrogen and phosphorus. I have studied nutrient limitation of bacterial growth in soil using a novel technique, where thymidine or leucine incorporation is used to detect changes in growth rates after adding nutrients.
