1. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil
Sammanfattning : 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. LÄS MER
2. Wood-Decomposing Fungi: Soil colonization, effects on indigenous bacterial community in soil and hydroxyl radical production
Sammanfattning : 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. LÄS MER
3. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status
Sammanfattning : 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. LÄS MER
Sammanfattning : Background Coagulase-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). LÄS MER
5. Assembly Mechanisms in Aquatic Bacterial Communities : The Role of Disturbances, Dispersal and History
Sammanfattning : 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. LÄS MER
