  1. 1. Character and Function of Anammox Bacteria under Environmental Stress

    Författare :Ola Bäckman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anammox; N-cycle; environmental stress; redox oscillations; anammoxosome; key proteins;

    Sammanfattning : During the last few decades observations of novel processes involved in nitrogen transformations have fundamentally challenged the view of pathways and controlling mechanisms during local and global nitrogen cycling. Anaerobic ammonium oxidation (anammox) constitutes one of these new pathways where autotrophic bacteria oxidize ammonium by nitrite to dinitrogen gas under anaerobic conditions. LÄS MER

  3. 2. Oscillatory phenomena in chloroplasts from spinach cotyledons

    Författare :Gertrud Puu; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A suspensionofchloroplasts, isolated from spinach cotyledons, was found to be an oscillatory system, i.e. a system in which one parameter (or more) varies over time in a fairly regular way.The oscillations, with a period of fifteen to twenty minutes,occured spontaneously in the light as well as in the dark and were self-sustained for several hours.

  4. 3. Systems biology techniques show high prevalence of post-translational regulation in the cyanobacterium Synechocystis PCC 6803

    Författare :Jan Karlsen; Elton Paul Hudson; Martin Hagemann; KTH; []
    Nyckelord :systems biology; sustainable development; omics; ribosome profiling; RNA sequencing; proteomics; genetic engineering; bioproduction; cyanobacteria; gene regulation; metabolism; translational regulation; post-translational regulation; bioinformatics; Bioteknologi; Biotechnology;

    Sammanfattning : Earth's climate has been upset by carbon dioxide (CO2) emissions from human activities and the use of fossil resources. To prevent catastrophic events on the environment and on civilizations, we urgently need to develop alternative solutions that utilize renewable resources. LÄS MER

  5. 4. Organic bioelectronic devices to control cell signalling

    Författare :Karin Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The nervous system consists of a network of specialized cells that coordinate the actions of the body by transmitting information to and from the brain. The communication between the nerve cells is dependent on the interplay of both electrical and chemical signals. LÄS MER
