  1. 1. Engineering Saccharomyces cerevisiae for mixed-sugar fermentation

    Författare :Rosa Garcia Sanchez; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; evolutionary engineering; promoter; mixed-sugar utilization; galactose; arabinose; xylose; Saccharomyces cerevisiae; fermentation; ethanol; phosphoglucomutase;

    Sammanfattning : Efficient fermentation of all the monomeric sugars derived from lignocellulose is crucial to increase the economy of bioethanol production, since they can account for a considerable fraction of the fermentable sugars in the raw material. This thesis describes the engineering of Saccharomyces cerevisiae strains for improved xylose, galactose and/or arabinose utilization. LÄS MER

  2. 2. Advancing Metabolic Engineering through Combination of Systems Biology and Adaptive Evolution

    Författare :Kuk-ki Hong; Chalmers tekniska högskola; []

    Sammanfattning : Understanding evolutionary strategies of microorganisms may provide opportunities foradvanced strain development with the aim to produce valuable bio-products from renewablebiomass resources. Through evolutionary processes, microorganisms can attain new traitsassociated with genetic changes that may be useful for the construction of improved strains. LÄS MER

  3. 3. Molecular mechanisms of aging in MTDNA mutator mice

    Författare :Daniel Henry Sven Edgar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mitochondria are intensely studied in the field of aging. mtDNA mutator mice have a proofreading deficiency in the mitochondrial DNA polymerase POLG, which causes a large amount of point mutations to be accumulated in mitochondrial DNA. These mice have mitochondrial dysfunction and experience a range of premature aging phenotypes. LÄS MER

  4. 4. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

    Författare :Evelina Kulcinskaja; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

    Sammanfattning : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. LÄS MER
