  2. 1. Insights into the metabolism of Clostridium thermocellum for cellulosic ethanol production

    Author : Johannes Yayo; Antonius J. A. van Maris; Richard Sparling; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; ethanol; glucose; fructose; amino acids; pyrophosphate; chaotropicity; thermodynamic driving force; laboratory evolution; chemostats; metabolic engineering; Biotechnology; Bioteknologi;

    Abstract : The societal goal of reaching net-zero CO2 emissions requires development of integrated biorefineries to produce biomass-derived fuels and chemicals. For sustainable second-generation bioethanol production, consolidated bioprocessing with the thermophile Clostridium thermocellum is regarded as a promising concept in view of the microorganism’s native ability to efficiently degrade plant cell wall material.

  4. 2. Succinic acid production using metabolically engineered Escherichia coli

    Author : Christian Andersson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). To date, the primary emphasis has been placed on the replacement of oil for transportation fuels. READ MORE

  5. 3. Biobased production of succinic acid by Escherichia coli fermentation

    Author : Christian Andersson; Gen Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). The present thesis illustrates different aspects of biobased succinic acid production by a metabolically engineered E. coli strain. READ MORE

  6. 4. Molasses Purification and Valorisation : Towards a sustainable production of hydroxymethylfurfural

    Author : Mikael Sjölin; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugar beet molasses; 5-hydroxymethylfurfural; membrane filtration; hydrolysis; dehydration; adsorption; purification; solvent regeneration;

    Abstract : The industrial transition from petrochemical-based to a more sustainable and circular economy requires the utilisation of renewable biobased raw materials that do not compete with other important industries, such as the food sector, preferably wastes or low value by-products. 5-hydroxymethylfurfural (HMF) is a versatile platform chemical that has great potential for utilisation in various sectors in a future bioeconomy, as it can be produced from sugars.

  7. 5. A phenotypic study of a unique respiratory strain of Saccharomyces cerevisiae and its application in protein production

    Author : Cecilia Ferndahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : During aerobic growth at high glucose concentrations, the yeast Saccharomyces cerevisiae prefers to catabolise glucose through fermentation rather than through respiration. Previously fully respiratory growth could only be achieved when a low external glucose concentration was maintained, in fed-batch and continuous cultures, but since the development of the respiratory strain, TM6*, in our laboratory this can now be achieved even at high external glucose concentration.
