  1. 1. Microbiological analysis of municipal wastewater treating photobioreactors

    Författare :Ivo Krustok; Monica Odlare; Emma Nehrenheim; Jaak Truu; Raul Muñoz; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photobioreactors; wastewater treatment; microalgae; microbiology; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Microalgae reactors, commonly known as photobioreactors, have become increasingly popular as an alternative for wastewater treatment. These systems reduce pollutants and remove nutrients such as nitrogen and phosphorous compounds from wastewater utilizing microalgae and bacteria. LÄS MER

  2. 2. Algal-Bacterial Photobioreactors for the Degradation of Toxic Organic Pollutants

    Författare :Raul Munoz; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; symbiosis.; nutrient removal; heavy metals removal; Algal-bacterial systems photobioreactors; toxic organic pollutants;

    Sammanfattning : The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. LÄS MER

  3. 3. Communities of microalgae and bacteria in photobioreactors treating municipal wastewater

    Författare :Ivo Krustok; Monica Odlare; Emma Nehrenheim; Jaak Truu; Catherine Legrand; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Everyone who uses water produces wastewater. This inevitability creates several problems that increase with the growth of the population and industry. LÄS MER

  4. 4. Heterocystous cyanobacteria, Dps proteins and H2 production

    Författare :Christoph Howe; Karin Stensjö; Felix Howe; Nir Keren; Uppsala universitet; []
    Nyckelord :H2 production; Cyanobacteria; Dps; ferritin-like proteins; iron; nutrient limitation; oxidative stress; biofilm; photobioreactor; iron homeostasis; H2O2;

    Sammanfattning : To mitigate climate change, CO2-emitting technologies have to be exchanged by renewable alternatives such as H2. H2 can be produced by cyanobacteria, but major efforts to enhance H2 production yields by genetic modifications or optimised cultivation conditions resulted in energetic photo-to-H2 conversion efficiencies of 4.
