  2. 11. Acid Tolerance of Streptococcus Mutans Biofilms

    Author : Jessica Neilands; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acid tolerance; Streptococcus mutans; Biofilms; Acid stress; Fluoride;

    Abstract : Mikrobiologisk forskning har till stor del bedrivits genom att man odlat bakterier i näringslösningar och på agarplattor och sedan studera bakterierna på olika sätt. Detta sätt att odla bakterier överensstämmer inte särskilt bra med hur bakterier växer i verkligenheten. READ MORE

  4. 12. Coping with environmental stress : from the individual and population perspective

    Author : Johanna Gardeström; Michael Tedengren; Tina Elfwing; Mats Grahn; Gary Carvalho; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental stress; Genetic diversity; Multi-level approach; Invertebrates; Marine ecology; Marin ekologi; Systems Ecology; systemekologi;

    Abstract : Natural stress and disturbances are important factors affecting the structure and function of ecosystems. However the magnitude of stress has escalated due to anthropogenic activities. Environmental monitoring and toxicity assessments try to protect ecosystems from unwanted human alterations. READ MORE

  5. 13. Improving Stress Tolerance in Industrial Saccharomyces cerevisiae Strains for Ethanol Production from Lignocellulosic Biomass

    Author : Valeria Wallace; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; lignocellulose; ethanol; inhibitors; temperature; stress tolerance;

    Abstract : The present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors.

  6. 14. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco

    Author : Jenny Lindberg; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Abiotic stress; compatible solutes; osmotic stress; osmoprotectants; trehalose; calmodulin; E. coli; N. tabacum; genetic engineering; Biotechnology; Bioteknik; Biochemistry; Metabolism; Biokemi; metabolism; glycine betaine;

    Abstract : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. READ MORE

  7. 15. Tolerance and antagonism to allopregnanolone effects in the rat CNS

    Author : Sahruh Turkmen; Inga-Maj Johansson; Agneta Nordberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; GABA-A receptor; UC1011; Spatial memory; Morris Water Maze; Tolerance; Silent second; mRNA; Obstetrics and gynaecology; Obstetrik och gynekologi;

    Abstract : Many studies have suggested a relationship between sex steroids and negative mental and mood changes in women. Allopregnanolone, a potent endogenous ligand of the GABA-A receptor and a metabolite of progesterone, is one of the most accused neuroactive steroids. READ MORE
