  1. 1. TOXICITY DRIVERS IN CHEMICAL MIXTURES FROM THE SWEDISH WEST COAST – EFFECTS ON PELAGIC COMMUNITIES

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Helena Hartmann; [2023-06-26]
    Nyckelord :;

    Sammanfattning : Human society benefits from a range of ecosystem services provided by the oceans, such as oxygen production, carbon storage, and fishing. However, these services are relying on the ecosystem’s functional and structural integrity, which are correlated to its biodiversity. LÄS MER

  3. 3. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anna Osterman; [2023]
    Nyckelord :Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Sammanfattning : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. LÄS MER

  4. 4. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Hana Faulds; [2023]
    Nyckelord :Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  5. 5. Missfärgningar av träfasader : En studie av tre områden i Gävle

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Moa Mattsson; Cordelia Sjöstrand; [2023]
    Nyckelord :Alger; missfärgningar; Gävle; fasad; fukt; biologisk påväxt; trä; småhus; enkät;

    Sammanfattning : Building façades can be affected by mould, algae and cyanobacteria which, through their dark pigments in the cells, can cause discoloration on the façade. These organisms are affected, among other things, by the availability of water and the air humidity. LÄS MER
