  1. 21. Translational accuracy, ribozyme efficiency and NAD metabolism in Escherichia coli

    Författare :Martin Stancek; Leif Isaksson; Lars Hederstedt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; translational accuracy; nicotinate mononucleotide adenylyltransferase; Microbiology; Mikrobiologi;

    Sammanfattning : Interactions between the translational machinery and mRNA in Escherichia coli have been studied. In the first section nonsense codon readthrough and changed translational reading frame were measured in different growth phases. LÄS MER

  3. 22. Growth rate control of periplasmic product retention in Escherichia coli

    Författare :Emma Bäcklund; Gen Larsson; Stefan Schmidt; Amelie Eriksson Karlström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Escherichia coli; fed-batch; outer membrane proteins; recombinant proteins; specific growth rate; periplasmic retention; phosphotransferase system; high cell density cultivation; acetate formation; Bioengineering; Bioteknik;

    Sammanfattning : The recombinant product is secreted to the periplasm in many processes where E. coli is used as host. One drawback with secretion is the undesired leakage of the periplasmic products to the medium. The aim of this work was to find strategies to influence the periplasmic retention of recombinant products. LÄS MER

  7. 25. Strategies for improved Escherichia coli bioprocessing performance

    Författare :Johan Jarmander; Gen Larsson; Thomas Egli; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E. coli; Salmonella; surface expression; autotransport; AIDA-I; lignocellulose; glucose; xylose; arabinose; simultaneous uptake; 3HB; Bioteknologi; Biotechnology;

    Sammanfattning : Escherichia coli has a proven track record for successful production of anything from small molecules like organic acids to large therapeutic proteins, and has thus important applications in both R&D and commercial production. The versatility of this organism in combination with the accumulated knowledge of its genome, metabolism and physiology, has allowed for development of specialty strains capable of performing very specific tasks, opening up opportunities within new areas.
