  2. 1. Interaction between crayfish and some microorganisms; Effect of temperature

    Author : Gül Gizem Korkut; Chadanat Noonin; Kenneth Söderhäll; Javier Diéguez Uribeondo; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Innate immunity, which constitutes the first line of defense in vertebrates, is the only immune system that invertebrates rely on to protect themselves from pathogens. The invertebrate immune system is composed of cellular and humoral components. Cellular immunity is phagocytosis, opsonization and encapsulation. READ MORE

  4. 2. Xylitol and its effect on oral ecology : clinical studies in children and adolescents

    Author : Pernilla Lif Holgerson; Svante Twetman; Christina Stecksén-Blicks; Eva Söderling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chewing gum; dental plaque; dose-response relationship; interdental plaque-pH; oral microorganisms; saliva; xylitol; Paedodontics; Pedodonti;

    Abstract : Xylitol, classified as a natural sugar substitute, has for about 35 years been known as an agent that may act against caries. The mechanism of action; how it inhibits mutans streptococci (MS) and the clinical dose-response relationship are not however fully investigated. READ MORE

  5. 3. Sulphur-Utilizing Microorganisms in Biotechnological Applications - Rubber Recycling and Vanadium Reduction

    Abstract : Membrane bioreactors (MBRs) show great promise for productivity improvement and energy conservation in conventional bioprocesses for wastewater reclamation. In order to attain high productivity in a bioprocess, it is crucial to retain the microorganisms in the bioreactors by preventing wash out. READ MORE

  7. 5. Sustained and triggered release by microencapsulation
