    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

  4. 3. Engineering cyanobacteria for increased growth and productivity

    Författare :Feiyan Liang; Peter Lindblad; Pia Lindberg; Olaf Kruse; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; CBB cycle; growth; biomass; photosynthesis; ethanol;

    Sammanfattning : Increasing the photosynthetic efficiency is one of the strategies to increase the crop yields to meet the requirement of 50% more food by 2050. Due to the similarity on photosynthesis between crops and cyanobacteria, cyanobacteria are ideal alternatives to study photosynthesis since cyanobacteria are prokaryotes, easier to engineer and have shorter life cycle.

  5. 4. Biochemical studies of thiamine deficiency in Baltic salmon (Salmo salar)

    Författare :Gun Åkerman; Lennart Balk; Björn Brunström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental toxicology; Miljötoxikologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The first part of this thesis is about the development of a method to inject various substances into the yolk of fish eggs. The method was named nanoinjection and enabled the injection of volumes as small as 10-9 L into the yolk of single fish eggs directly after fertilization, with insignificant mortality due to the injection.
