  2. 11. The GRE3 encoded aldo-keto reductase and its influence on xylose fermentation in recombinant Saccharomyces cerevisiae strains

    Author : Karin Träff; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Biokemisk teknik; dihydroxyacetone phosphate; xylose reductase; xylose; xylose isomerase; GRE3; Saccharomyces cerevisiae; aldo-keto reductase;

    Abstract : The aim of the work presented in this thesis was to improve ethanol formation from xylose in recombinant Saccharomyces cerevisiae strains. This was achieved by decreasing the xylitol by-product formation. Gre3p is the major xylose-reducing enzyme in S. cerevisiae. READ MORE

  4. 12. Designing simultaneous saccharification and co-fermentation of lignocellulose for improved xylose conversion

    Author : Kim Olofsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; lignocellulose; simultaneous saccharification and co-fermentation; xylose fermentation;

    Abstract : Fuel ethanol from lignocellulose is one sustainable alternative to the fossil fuels of today. All sugars in the material must be utilized in order to achieve high overall ethanol yields. Baker’s yeast, Saccharomyces cerevisiae, has been engineered to ferment the pentose sugar xylose from lignocellulose to ethanol. READ MORE

  5. 13. An Emulation-Based Performance Evaluation Methodology for Edge Computing and Latency Sensitive Applications

    Author : Manuel Osvaldo Jesús Olguín Muñoz; James Gross; Karl H. Johansson; Yu Xiao; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Edge Computing; Performance Evaluation; Latency-sensitive Applications; Distributed Systems; Emulation; Extended Reality; Cyber-Physical Systems; Networked Control Systems; Wearable Cognitive Assistance; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Cloud Computing, with its globally-accessible nature and virtually unlimited scalability, has revolutionized our daily lives since its widespread adoption in the early 2000s. It allows us to access our documents anywhere, keep in touch with friends, back up photos, and even remotely control our appliances. READ MORE

  6. 14. Metabolic Engineering of the Pentose Phosphate Pathway of Xylose Fermenting Saccharomyces cerevisiae

    Author : Björn Johansson; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; xylulokinase; pentose phosphate pathway; genetic engineering; Saccharomyces cerevisiae; xylose; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The aim of the work presented in this thesis is the improvement of xylose fermentation performance of recombinant Saccharomyces cerevisiae strains expressing XYL1 and XYL2 from Pichia stipitis, encoding xylose reductase (XR) and xylitol dehydrogenase (XDH). A recombinant strain of S. READ MORE

  7. 15. PET studies on the mechanism of monoaminergic drugs

    Author : Magdalena Nord; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Positron emission tomography (PET) is a molecular imaging technique that allows for examinations of neurochemistry directly in the living human brain. In the present thesis, PET was used to assess the pharmacological effects of two drugs representing the major classes of antipsychotic and antidepressant drugs. READ MORE
