2. 11. Food ingredients from cultivated seaweeds-Improving storage stability and protein recovery

   Author : Hanna Harrysson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unsaturated fatty acids; macroalgae; alterative cultivation; sequential recovery; pH-shift; ascorbic acid; long-term storage; Seaweed; protein extraction; proteins; lipid oxidation;

   Abstract : There is a global demand for new vegetarian protein sources, and seaweed have for multiple reasons been identified as a promising candidate. The overall aim of this thesis was to evaluate the potential of three different Swedish seaweed species as food protein sources, but also as sources of unsaturated fatty acids, vitamins and minerals.

4. 12. Habitat-Forming Seaweeds in a Changing Climate

   Author : Alexandra Kinnby; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean acidification; Warming; Freshening; Temperature; Salinity; pH; pCO2; Fucus vesiculosus; Phlorotannins; Grazing; Tissue resilience; Macroalgae;

   Abstract : Climate change is an umbrella term encompassing some of the largest and most potent selective pressures currently acting on ecosystems. It can have diverse effects on marine systems; the most powerful of which are changes to salinity through altered patterns of precipitation and evaporation, temperature through increased global temperature, and pH through the dissolution of CO2 into seawater where it ultimately reacts with water to form carbonate (CO32-) and hydrogen ions (2H+).

5. 13. Evaluating Swedish seaweeds for biorefinery

   Author : Joakim Olsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; proteins; carbohydrates; salinity; chemical composition; ulvan; variation; Ulva spp.; Seaweed; macroalgae; hydrothermal liquefaction;

   Abstract : A sustainable future demands a transition from oil to biomass to produce fuels, chemicals, commodities, and energy. However, to generate the predicted amount of bioenergy required by 2050, all the biomass harvested today should be utilized. One type of biomass that has received relatively little attention is seaweeds. READ MORE

6. 14. Phytobenthic communities in the Baltic Sea - seasonal patterns in settlement and succession

   Author : Susanne Qvarfordt; Hans Kautsky; Lena Kautsky; Hendrik Schubert; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Succession; settlement; recruitment; phytobenthos; macroalgae; invertebrates; Baltic Sea; community; Biology; Biologi;

   Abstract : Seasonal changes in reproduction, recruitment, occurrence and growth of marine plant and animal species is a common phenomenon world-wide. This thesis investigates whether such seasonal changes could determine the succession in subtidal phytobenthic communities on free space in the Baltic Sea. READ MORE

7. 15. Seaweeds as a future protein source: innovative cultivation methods for protein production

   Author : Kristoffer Stedt; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Saccharina latissima; Ulva fenestrata; Ulva intestinalis; Chaetomorpha linum; Cultivation conditions; Nitrogen content; Amino acids; Heavy metals; Food safety; Wastewater; Process water; Circularity; Blue economy;

   Abstract : As the global population is projected to reach approximately 10 billion people by 2050, it is estimated that we will need to produce up to 60% more food compared to 2010. Although the current food production system contributes to 25% of greenhouse gas emissions worldwide, accounts for 70-80% of eutrophication and freshwater usage, and occupies half of all ice- and desert-free land, it fails to meet the global nutritional needs.
