  1. 1. 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.

  3. 2. Circular Economy in a Plastic World: How can emerging technologies enable the transition?

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Alejandro Aristi Capetillo; [2021]
    Keywords : circular economy; emerging technologies; plastics value chain; sustainability transitions; systematic literature review; ReSOLVE framework; Multilevel Perspective Framework; Business and Economics; Technology and Engineering; Social Sciences;

    Abstract : Plastic waste has brought a severe pollution problem that demands immediate attention. Promoted by policymakers, academia, and corporations alike, the circular economy model presents a viable path to sustainable development. Likewise, the emergence of disruptive technologies promises a profound and imminent socio-technical transformation. READ MORE

  4. 3. Fractionation of Wheat Bran for Utilisation in Biorefinery

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gabriella Haag; [2021]
    Keywords : Wheat bran; biorefinery; chemical engineering; vetekli; bioraffinaderi; extraction; Technology and Engineering;

    Abstract : Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. READ MORE

  5. 4. Modeling transport phenomena with COMSOL Multiphysics - Adsorptive membrane fouling in lignocellulosic biorefineries and lessons learned from it

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Linnéa Petersson; [2020]
    Keywords : QCM-D; Quartz crystal microbalance with dissipation monitoring; Hemicellulose; GGM; Galactoglucomannans; Adsorption; Membrane fouling; COMSOL; Chemical engineering; Kemiteknik; Technology and Engineering;

    Abstract : The separation of hemicelluloses, like glactoglucomannans, from lignocellulosic process streams is an important step in building profitable lignocellulosic biorefineries. The most common method for the separation is membrane filtration, however, it has the draw-back of being sensitive to membrane fouling. READ MORE

  6. 5. Evaluating Sugar Signaling during Xylose Oxidation in Saccharomyces cerevisiae

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Viktor Persson; [2020]
    Keywords : Saccharomyces cerevisiae; yeast; xylose oxidation; sugar signaling; biosensor; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : The sugar signaling state of cells oxidizing xylose was investigated through the chromosomal integration of the Weimberg pathway into previously established biosensor strains capable of monitoring the Snf3p/Rgt2p, SNF1/Mig1p, and cAMP/PKA pathways through the expression of HXT1, SUC2, and TPS1, respectively. Ultimately, two new strains were successfully developed containing both the Weimberg pathway and a biosensor for either HXT1 (TMB CB 112) or TPS1 (TMB CB 117). READ MORE
