1. Marine nitrogen fixation : Cyanobacterial nitrogen fixation and the fate of new nitrogen in the Baltic Sea
Sammanfattning : Biogeochemical processes in the marine biosphere are important in global element cycling and greatly influence the gas composition of the Earth’s atmosphere. The nitrogen cycle is a key component of marine biogeochemical cycles. LÄS MER
2. 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
3. Causes and consequences of Gonyostomum semen blooms
Sammanfattning : Aquatic ecosystems provide essential ecosystem services, but are also highly vulnerable to global change. Climate change, eutrophication and browning, for example, collectively drive the increase of harmful algal blooms in freshwaters. LÄS MER
4. Functional Profiling Of Metabolic Regulation In Marine Bacteria
Sammanfattning : Oceans are powered by active, metabolically diverse microorganisms, which are important in regulating biogeochemical cycles on Earth. Most of the ocean surface is often limited by nutrients, influencing bacterial growth and activities. LÄS MER
5. Increased Carbon Fixation for Chemical Production in Cyanobacteria
Sammanfattning : The combustion of fossil fuels has created many environmental problems, the major one, the greenhouse effect. Thus, we need solutions in order to replace fossil fuels and recycle the CO2 in the atmosphere. Renewable energies have created attention the last decades but electricity is the main energy form obtained. LÄS MER
