  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; [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. Wood-Decomposing Fungi: Soil colonization, effects on indigenous bacterial community in soil and hydroxyl radical production

    University dissertation from Microbial Ecology, Lund University

    Author : Karin Tornberg; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; hydroxyl radicals; fungal growth; interactions; soil colonization; bacterial community; soil; brown-rot fungi; wood-decomposing fungi; white-rot fungi; Ekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The extracellular enzyme activities of wood-decomposing basidiomycetes are essential for wood degradation, but are also able to degrade various recalcitrant organic pollutants. The possible application of wood-decomposing fungi in bioremediation has increased the interest in understanding their growth and activity in soil. READ MORE

  3. 3. 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; [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 : Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. READ MORE

  4. 4. Molecular epidemiology of coagulase-negative staphylococci in hospitals and in the community

    University dissertation from Umeå : Umeå university

    Author : Micael Widerström; Johan Wiström; Tor Monsen; Anders Sjöstedt; Bo Söderquist; [2010]

    Abstract : BackgroundCoagulase-negative staphylococci (CoNS) and in particular Staphylococcus epidermidis have emerged as major pathogens primarily causing nosocomial infections in patients with indwelling medical devices. These infections are often caused by multidrug-resistant strains of S. epidermidis (MDRSE). READ MORE

  5. 5. Assembly Mechanisms in Aquatic Bacterial Communities The Role of Disturbances, Dispersal and History

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mercè Berga Quintana; Silke Langenheder; Eva Lindström; Örjan Östman; Mathew Leibold; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; diversity; community composition; metacommunity;

    Abstract : Environmental conditions, biotic interactions, dispersal and history have been suggested to be important processes influencing the spatial distribution of organisms and thus to affect community assembly. Understanding how these processes influence community assembly is important, particularly because community diversity and composition are suggested to be relevant for ecosystem functioning. READ MORE
