  1. 1. Characterization of c-di-GMP signaling in Salmonella typhimurium

    Author : Roger Simm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Signal transduction via cyclic nucleotides is a general mechanism utilized by cells from all kingdoms of life. Identification of cyclic diguanosine monophosphate (c-di-GMP) as an allosteric activator of the cellulose synthase in Gluconacetobacter xylinus 20 years ago, paved the way for the discovery of a novel general signalling system which is unique to bacteria.

  2. 2. Role of c-di-GMP signalling in bacterial-host interactions

    Author : Agaristi Lamprokostopoulou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Bacteria have various ways to sense environmental signals and to adapt their behavior and physiology through different signaling systems. Secondary messenger signaling, amplified by enzymatic activity, rapidly transmits a signal in the cell, resulting in allosteric functional control. READ MORE

  3. 3. Global regulatory factors that impact metabolic and lifestyle choices in Pseudomonas putida

    Author : Lisa Wirebrand; Victoria Shingler; Matthew Francis; Carlos Balsalobre; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Pseudomonas putida; c-di-GMP; motility; ppGpp; DksA; biofilm dispersal; transcriptional and translational regulation; dmp-system; phenol catabolism; carbon repression control; plasmid stability;

    Abstract : Pseudomonas putida strains have a broad metabolic capacity and are innately resistant to many harmful substances – properties that make them of interest for a number of industrial and biotechnological application. They can rapidly adapt to changes in physico-chemical parameters in the soil and water environments they naturally inhabit. READ MORE

  4. 4. Metabolism-dependent taxis and control of motility in Pseudomonas putida

    Author : Sofia Österberg; Vicky Shingler; Caroline Harwood; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Motility; c-di-GMP; metabolism-dependent taxis; receptors; transcription; Pseudomonas putida; molekylärbiologi; Molecular Biology;

    Abstract : Bacteria living in soil and aquatic habitats rapidly adapt to changes in physico-chemical parameters that influence their energy status and thus their ability to proliferate and survive. One immediate survival strategy is to relocate to more metabolically optimal environments. READ MORE

  5. 5. Exploring strategies to improve volumetric hydrogen productivities of Caldicellulosiruptor species

    Author : Thitiwut Vongkampang; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor kronotskyensis; volumetric hydrogen productivity; non-diauxic; acrylic fibres; cell immobilization; chitosan; biofilm; c-di-GMP; cellobiose; xylose; consolidated bioprocessing; heat-treated wheat straw;

    Abstract : Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. READ MORE
