  1. 1. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil

    University dissertation from Section of Biological and Earth Sciences

    Author : Louise Aldén; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antibiotics; Bacteria; Community; Fungi; Leucine incorporation; Phenols; Soil; Pollution-Induced Community Tolerance PICT ;

    Abstract : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. READ MORE

  2. 2. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status

    University dissertation from Department of Ecology, Lund University

    Author : Katarina Söderberg; Lunds universitet.; Lund University.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CLPP; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Biolog; PLFA; mycorrhizal status; nitrogen addition; along roots; plant species; root age; thymidine and leucine incorporation; bacterial composition; Rhizosphere; bacterial activity;

    Abstract : Popular Abstract in Swedish Växter påverkar marken rent mekaniskt genom att jordstrukturen ändras när en rot växer, men också kemiskt genom att rötterna utsöndrar organiska molekyler. De organiska molekylerna ökar näringstillgången för mikroorganismerna i marken och därmed ändras tillväxthastigheten och biomassan hos mikroorganismerna. READ MORE

  3. 3. Nutrient Limitation of Bacterial Growth in Soil

    University dissertation from Department of Ecology, Lund University

    Author : Fredrik Demoling; Lunds universitet.; Lund University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; Fertilization; Bacteria; Soil; Fungi; Thymidine or Leucine incorporation; Growth limitation; Phosphorus; Nitrogen; Carbon;

    Abstract : 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.

  4. 4. Structure and function of microbial communities in constructed wetlands - influence of environmental parameters and pesticides on denitrifying bacteria

    University dissertation from Department of Ecology, Lund University

    Author : Susann Milenkovski; Lunds universitet.; Lund University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fungicide; concentration-response curves; nosZ; nirS; nirK; bacterial activity; denitrification; bacterial community composition; herbicide; insecticide;

    Abstract : This thesis addresses the interactions and relationships between natural aquatic bacterial communities, environmental parameters, anthropogenic chemicals and the denitrification pathway in the habitat of agricultural constructed wetlands. The main aim was to gain fundamental knowledge of the drivers behind the processes of the denitrification (i.e. READ MORE

  5. 5. On the Ecology of Saprotrophic Fungi and Bacteria in Soil: Biotic and Abiotic Control of Growth Rates

    University dissertation from Department of Ecology, Lund University

    Author : Johannes Rousk; Lunds universitet.; Lund University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; decomposer ecology; soil pH; temperature relationship; Fungal growth; litter decomposition; bacterial growth; C:N;

    Abstract : Two groups of organisms dominate the decomposition in soil: fungi and bacteria. One of the most important parameters to optimise for any organism is its growth, and thus a direct way to study the effect of environmental factors on fungi and bacteria in soil is to measure their growth rate.
