  1. 16. Intracellular vesicles induced by monotopic membrane protein in Escherichia coli

    Författare :Hanna M. Eriksson; Åke Wieslander; Meta Kuehn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; intracellular vesicles; Escherichia coli; glycosyltransferase; overexpression; optimization; detergent; screening; lipid composition; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : The monotopic membrane protein alMGS, a glycosyltransferase catalyzing glucolipid synthesis in Acholeplasma laidlawii, was overexpressed in Escherichia coli. Optimization of basic growth parameters was performed, and a novel method for detergent and buffer screening using a small size-exclusion chromatography was developed. LÄS MER

  3. 17. Cell division in Escherichia coli

    Författare :Karl Skoog; Daniel O. Daley; Miguel Vicente; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Sammanfattning : The Gram-negative bacterium Escherichia coli is a model system to describe the biochemistry and cell biology of cell division in bacteria. This process can be divided into three major steps. The first step involves the replication of the DNA, followed by an elongation step in which the cells become twice as long. LÄS MER

  4. 18. Glycosphingolipid interactions of Helicobacter pylori and F1C-fimbriated Escherichia coli

    Författare :Niamh Roche; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; F1C fimbriae; Escherichia coli; glycosphingolipids; microbial adhesion; mass spectrometry;

    Sammanfattning : The aim of this thesis was to investigate glycosphingolipid interactions of the human pathogens Helicobacter pylori and F1C-fimbriated uropathogenic Escherichia coli. Of particular interest were interactions of H. pylori to complex gangliosides, the role played by H. LÄS MER

  5. 19. Transport and Fate of Escherichia coli in Unsaturated Porous Media

    Författare :Emma Engström; Berit Balfors; Chin-Fu Tsang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contaminant transport modeling; Bacterial fate; Unsaturated zone; Retention; Straining; Escherichia coli;

    Sammanfattning : The unsaturated zone could provide an effective barrier against pathogenic microbes entering the groundwater. Knowledge relating to microbial fate in this zone is therefore important for increased understanding of groundwater vulnerability. LÄS MER

  7. 20. Enhancing membrane and secretory protein production yields in Escherichia coli

    Författare :Zhe Zhang; Jan-Willem de Gier; Claes von Wachenfeldt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; recombinant protein production; Escherichia coli; membrane protein; secretory protein; strain engineering; Biochemistry; biokemi;

    Sammanfattning : Proteins fulfill essential functions in living cells. To produce sufficient amounts of a protein is essential to study the structure and function of a protein, or to use it for medical purposes. Escherichia coli is a Gram-negative bacterium that is widely used for recombinant protein production. LÄS MER
