1. On thermodynamic and kinetic constraints in autotrophic metabolism
Sammanfattning : Earth has entered a new geological epoch, the Anthropocene, defined by humanity’s impact on the environment with increased emissions of CO2 due to burning of fossil resource as a major contributor. To ensure a sustainable future, humanity has to move towards a circular economy, where released CO2 is re-captured and turned into resources. LÄS MER
2. Explaining temporal variations in soil respiration rates and delta13C in coniferous forest ecosystems
Sammanfattning : Soils of Northern Hemisphere forests contain a large part of the global terrestrial carbon (C) pool. Even small changes in this pool can have large impact on atmospheric [CO2] and the global climate. LÄS MER
3. Autotrophic and heterotrophic culture of Nordic microalgae in wastewater for lipid production
Sammanfattning : It is well established that society’s main means for producing energy, the combustion of fossil fuels, is unsustainable and contributes to global warming. Microalgae have high potential for the production of biodiesel and energy source that can at least partially replace fossil fuels. LÄS MER
4. Nitrification and Nitrifying Bacterial Communities in Coniferous Forest Soils : Effects of Liming and Clear-Cutting
Sammanfattning : This thesis deals with the effects of liming and clear-cutting on nitrification in hemi-boreal and northern temperate coniferous forest soils. The approach has been to study both the potential nitrification and the community structure of the ammonia-oxidising bacteria, which carry out the first step of autotrophic nitrification. LÄS MER
5. Adaptations and constraints associated with autotrophy in microbial metabolism
Sammanfattning : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. LÄS MER
