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

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

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

    Abstract : 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.
