11. Denitrification as an adaptive trait in soil and groundwater bacteria
Sammanfattning : The focus of the thesis is on selection and adaptation processes in bacteria with emphasis on denitrifying bacteria in groundwater. Other nitrogen transformation processes such as dissimilatory nitrate reduction to ammonium (nitrate ammonification) and nitrification of forest soil bacteria are briefly discussed. LÄS MER
12. 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
13. Porphyrins and heme in microorganisms : Porphyrin content and its relation to phototherapy and antimicrobial treatments in vivo and in vitro
Sammanfattning : One of the greatest threats to human health is increasing antimicrobial resistance among pathogens, and finding alternatives for treatment of bacterial infections is of highest importance together with a more controlled use of antibiotics. Porphyrins and heme have both been shown to be a promising class of compounds for inactivation of bacteria; porphyrins by their excellent properties to act as a photosensitizer, and heme by its importance as an iron source during a bacterial infection in vertebrates.

14. Chemical signals in interactions between Hylobius abietis and associated bacteria
Sammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER
15. Comparative Genomics of Endosymbiotic Bacteria
Sammanfattning : Genomes of intracellular bacteria are thought to be the products of reductive evolution. They have evolved from ancestral genomes of free-living bacteria through a process of massive gene loss. LÄS MER
