1. Porphyrins and heme in microorganisms : Porphyrin content and its relation to phototherapy and antimicrobial treatments in vivo and in vitro
Abstract : 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.

2. Identification of bacteria associated with malaria mosquitoes - Their characterisation and potential use
Abstract : The use of transformed bacteria to stop or kill disease-causing agents in the gut of vector insects is called paratransgenics. Two of the major steps in creating a paratransgenic Anopheles mosquito, unable to spread the Plasmodium parasites that cause malaria, are to find a bacterium suitable for the purpose and a way to introduce the transformed bacterium into mosquitoes in the field.

3. Factors influencing the biogeography of bacteria in fresh waters - a metacommunity approach
Abstract : One of ecology’s primary goals is to comprehend biodiversity and its patterns of distribution over space and time. Since microorganisms play a pivotal role in key ecological processes, the diversity of microbial communities may have important implications for the stability and functioning of Earth’s ecosystems.

4. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules
Abstract : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. READ MORE

5. Attached Bacterial Communities in Lakes – Habitat-Specific Differences
Abstract : For many years, the importance of microorganisms attached to surfaces in littoral zones and wetlands has been disregarded when describing aquatic ecosystem dynamics. Supporting evidence is scarce but convincing that these microbial communities are not only very productive but can often serve as major regulators of nutrient and carbon dynamics in many freshwaters.
