  2. 1. Microalgae : future bioresource of the sea?

    Author : Martin Olofsson; Catherine Legrand; Jukka Seppälä; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; algal cultivation; bioresource; bioenergy; CO2 mitigation; multi-species community approach; seasonal variation; Akvatisk ekologi; Aquatic Ecology; Bioteknik; Biotechnology; Environmental technology; Miljöteknik;

    Abstract : Unicellular microalgae are a renewable bioresource that can meet the challenge forfood and energy in a growing world population. Using sunlight, CO2, nutrients,and water, algal cells produce biomass in the form of sugars, proteins and oils, allof which carry commercial value as food, feed and bioenergy. READ MORE

  4. 2. Revealing the potential of Nordic microalgae : turning waste streams into resources

    Author : Martin Plöhn; Christiane Funk; Leif J. Jönsson; Maria Barbosa; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; Biotechnology; bioremediation; Heavy metal; Biopolymer; Biodegradable; Sustainability; Chlorella vulgaris; Biochemistry; biokemi; environmental science; miljövetenskap;

    Abstract : As the world's population grows, the demand for fresh water, food, fuel, energy and modern technology increases tremendously. Not only does this require enormous amounts of resources but it also increases the amount of waste and especially wastewater. READ MORE

  5. 3. Wastewater treatment and biomass generation by Nordic microalgae : growth in subarctic climate and microbial interactions

    Author : Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; Umeå universitet; []

    Abstract : Nordic native microalgal strains were isolated, genetically classified and tested for their ability to grow in municipal wastewater. Eight of the isolated strains could efficiently remove nitrogen and phosphate in less than two weeks. Two of these strains, Coelastrella sp. READ MORE

  6. 4. Co-digestion of microalgae and sewage sludge - A feasibility study for municipal wastewater treatment plants

    Author : Jesper Olsson; Eva Thorin; Sebastian Schwede; Emma Nehrenheim; Raúl Muñoz Torre; Mälardalens högskola; []

  7. 5. Enhanced biogas production from municipal WWTPs : Co-digestion of microalgae with sewage sludge and thermophilic secondary digestion of mesophilic digested sludge

    Author : Jesper Olsson; Eva Thorin; Emma Nehrenheim; Raúl Muñoz Torre; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Biogas is produced when organic material is broken down in oxygen-free (anaerobic) conditions. This process is called anaerobic digestion and is used in most large and medium-sized municipal wastewater treatment plants in Sweden. READ MORE
