1. Microbial diversity in Baltic Sea sediments
Sammanfattning : This thesis focuses on microbial community structures and their functions in Baltic Sea sediments. First we investigated the distribution of archaea and bacteria in Baltic Sea sediments along a eutrophication gradient. LÄS MER
2. The Niches of Bacterial Populations in Productive Waters : Examples from Coastal Waters and Four Eutrophic Lakes
Sammanfattning : Recent research in microbial ecology has focused on how aquatic bacterial communities are assembled. Only a few of these studies follow a “Gleasonian” approach where the roles of single bacterial populations are in focus. LÄS MER
3. Ammonia-Oxidising Bacteria in Soil : Studies of diversity and abundance using 16S rRNA gene analysis
Sammanfattning : Nitrification is the process whereby ammonia is oxidised to nitrate. The first step of this process is carried out by the chemoautotrophic, ammonia-oxidising bacteria (AOB), which convert ammonia to nitrite. LÄS MER
4. Use of microbiomics to study human impacts on complex microbial communities
Sammanfattning : The study of bacterial communities in nature is currently a challenge. The majority of bacteria in clinical and environmental samples have not yet been cultured and therefore we cannot fully understand their roles in nature and how the ecological balance in a specific microbial ecosystem can be disrupted. LÄS MER
5. Physiological status of bacteria used for environmental applications
Sammanfattning : Several bacteria have properties of interest for biotechnological applications, such as bioremediation of pollutants and biocontrol of plant pathogens. In order to perform their intended tasks in the environment the cells need to remain viable and active. LÄS MER
