  4. 2. Enzyme Cold Adaptation through Evolution of Protein Flexibility

    Author : Jaka Sočan; Johan Åqvist; Hugo Gutiérrez-de-Terán; Janez Mavri; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; EVB; Empirical valence bond method; Pancreatic elastase; α-amylase; Enzyme catalysis; Enzyme evolution; Cold adaptation; Temperature dependence of catalytic rates; Psychrophilic enzyme; Molekylär biovetenskap; Molecular Life Sciences;

    Abstract : What lives, evolves. Macromolecular catalysis is a process, central to both evolutionary and metabolic aspect of life, as it provides a systematic bias favouring certain chemical processes. READ MORE

  5. 3. Metabolic Engineering of Recombinant Protein Production by Saccharomyces cerevisiae

    Author : Zihe Liu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recombinant protein production; genome sequencing; DNA microarray; insulin precursor; growth rate; UV mutation; yeast; anaerobic electron acceptor; secretory pathway; unfolded protein response; metabolic engineering; systems biology; α-amylase;

    Abstract : The yeast Saccharomyces cerevisiae is a widely used cell factory for the production of fuels, chemicals, and it also provides a platform for the production of many heterologous proteins of medical or industrial interest. In this thesis, random and rational approaches, such as vector design, host engineering, fermentation analysis, UV Mutation, coupled with high-throughput systems biology techniques (including whole genomic sequencing, microarray analysis and flux analysis) and integrated analysis (Reporter feature technique), were employed to engineer cellular properties more effectively and purposefully to construct cell factories for protein production.

  6. 4. Gliadin-Blocking Peptides In vitro assessment of their potential to alleviate celiac disease development

    Author : Karolina Hoffmann; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; high-gliadin affinity blocking peptides; Caco-2 cells; in vitro digestion; tissue transglutaminase; celiac disease; gliadin; α-amylase trypsin inhibitors;

    Abstract : This thesis work aimed to investigate the potential of synthetic peptides as agents to block wheat prolamins (gliadins) that trigger the development of symptoms in celiac disease. The first step of this investigation included selection and synthesis of peptides with high affinity to gliadins and assessment of the potential of these so-called blocking peptides to limit gliadin reactivity in vitro.

  7. 5. Validation of mild cooking processes with target of Listeria monocytogenes inactivation to ensure food safety

    Author : Sonja Karin Grönqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the use of Time Temperature Integrators (TTIs) to validate industrial cooking processes aimed to achieve a 6 logarithmic inactivation of Listeria monocytogenes, equal to a heat load of 2 min at 70 °C (P707.5 = 2) . To produce microbiological TTIs, live cells of L. monocytogenes were crossbound in alginate beads. READ MORE
