1. 6. Boreal Lake Sediments as Sources and Sinks of Carbon

   Författare :Cristian Gudasz; Tranvik Lars; David Bastviken; Susan Ziegler; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal lakes; allochthonous; lake sediments; sediment mineralization; bacterial production; bacterial biomass; carbon cycle; Freshwater ecology; Limnisk ekologi; Limnologi; Limnology;

   Sammanfattning : Inland waters process large amounts of organic carbon, contributing to CO2 and CH4 emissions, as well as storing organic carbon (OC) over geological timescales. Recently, it has been shown that the magnitude of these processes is of global significance. LÄS MER

3. 7. Productivity and carbon transfer in pelagic food webs in response to carbon, nutrients and light

   Författare :Carolyn Faithfull; Ann-Kristin Bergström; Tobias Vrede; Kathryn Cottingham; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial production; phytoplankton production; mesocosms; food webs; carbon; nutrients; light; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; limnologi; Limnology;

   Sammanfattning : Some of the major problems we face today are human induced changes to the nitrogen (N), phosphorus (P) and carbon (C) cycles. Predicted increases in rainfall and temperature due to climate change, may also increase dissolved organic matter (DOM) inflows to freshwater ecosystems in the boreal zone. LÄS MER

4. 8. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae

   Författare :Nina Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ethylene forming enzyme; Ethylene; respiration rate; Saccharomyces cerevisiae; cultivation; production; nitrogen metabolism; 2-oxoglutarate; enzyme engineering; metabolic modeling;

   Sammanfattning : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. LÄS MER

5. 9. Engineering microbial cell factories for protein production

   Författare :Kiavash Mirzadeh; Daniel Daley; Grzegorz Kudla; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein production; expression vector; recombinant DNA; Translation initiation region; Escherichia coli; mRNA secondary structure; Synthetic evolution; Biochemistry; biokemi;

   Sammanfattning : Proteins are often produced using microbial cell factories for academic or industrial purposes. Protein production is however not an open-and-shut procedure. Production yields often vary in an unpredictable and context dependent manner, limiting the rational design of a straightforward production experiment. LÄS MER

7. 10. Amines and Bacterial Vaginosis

   Författare :Helen Wolrath; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Bacterial Vaginosis (BY) is a common syndrome, with a prevalence of 10-30% in women of childbearing age. The decisive pathogenetic factoris thought to have a microbiological origin, but so far no specific bacteria have been implicated in causing BV. LÄS MER
