1. 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
2. The dissolved organic carbon released from lake phytoplankton : biochemical composition and bacterial utilization
Sammanfattning : .... LÄS MER
3. Bacterial use of allochthonous organic carbon for respiration and growth in boreal freshwater systems
Sammanfattning : Aquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere.

4. 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
5. Towards Anti-Virulence Antimicrobials, Discovery and Development of Sortase A Inhibitors and Investigations of Bacterial Phenotypes
Sammanfattning : Antibiotic resistance is an emerging and serious threat to public health. Immediate actions are required to preserve current antibiotics while intensifying research efforts towards the development of new effective therapeutics. LÄS MER
