  2. 1. Microalgal solutions in Nordic conditions : industries transition toward resource recovery?

    Author : Lina Mattsson; Catherine Legrand; Elin Lindehoff; Hanna Farnelid; Kristian Spilling; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; algal cultivation; polyculture; resource recovery; seasonal variation; industrial partnership; CO2 mitigation; nitrogen removal; community composition; Ecology; Ekologi; Environmental Biotechnology; Miljöbioteknik; Miljövetenskap; Environmental Science; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Abstract : Microalgal solutions can through photosynthesis recover greenhouse gas (CO2) and nutrients from industrial waste, reducing climate footprint and eutrophication. An added value to the process is algal biomass containing lipids, proteins, and carbohydrates with commercial potential for biofuel, feed, and fertilizer. READ MORE

  4. 2. Polybrominated diphenylethers in the environment - Local and long range transport

    Author : Arnout ter Schure; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Substance Flow Analysis; Spatial Variation; Sources; PCB; PBDE; Latitude; Global Fractionation; Frogs; Deposition; Atmosphere; Baltic Sea; Ekologi; Temperature; Washout ratio; Ecology;

    Abstract : I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. READ MORE

  5. 3. Uptake, turnover and distribution of chlorinated fatty acids in aquatic biota

    Author : Helena Björn; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; porpoise; fish; metabolism; food chain; respiration; membrane; phospholipid; chlorohydrins; lipid; Ecology; Ekologi;

    Abstract : Chlorinated fatty acids (ClFAs) are the major contributors of extractable, organically bound chlorine in fish lipids. A known anthropogenic source of ClFAs is chlorine bleached pulp production. Additional anthropogenic sources may exist, e.g. READ MORE

  6. 4. Sulfidic mine waste microorganisms in an ecological context

    Author : Gustav Ebenå; Erika Kothe; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The focus of this thesis are the microorganisms found in sulfidic minewaste and their ecology. The microorganisms are investigated from the point of view of being an important, if not the most important, factor in the production of acid rock drainage (ARD). The thesis is a summary of several studies. READ MORE

  7. 5. Nutrient Transfer in Aquaponic Systems – Optimizing microbial processes for greater circularity and economic viability

    Author : Victor P. Lobanov; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquaculture; Aquaponics; Controlled environment agriculture; Waste revalorization; Microbiology;

    Abstract : The trend towards sustainable process design in modern industries combines the goal of improving process efficiency with a conscientious shift towards resource conservation. Aquaponics, a system that involves co-cultivating fish and plants, is a waste-conscious food production system. READ MORE
