  2. 11. Characterization of Bacterial Biofilms for Wastewater Treatment

    Author : Sofia Andersson; Gunnel Dalhammar; Bo Mattiasson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biofilm; extracellular polymeric substances; exopolysaccharides; interspecies interactions; wastewater treatment; denitrification; phosphorus removal; Microbiology; Mikrobiologi;

    Abstract : Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess.

  4. 12. From genes to ecological function in marine bacteria

    Author : Neelam Akram; Jarone Pinhassi; Ian Hewson; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mikrobiologi; Microbiology;

    Abstract : Bacteria in the sea are constantly exposed to environmental challenges (e.g. variations in nutrient concentrations, temperature and light conditions), and therefore appropriate gene expression response strategies to cope with them efficiently are evolved. READ MORE

  5. 13. The type I-E CRISPR-Cas system : Biology and applications of an adaptive immune system in bacteria

    Author : Lina Amlinger; Magnus Lundgren; Peter Fineran; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CRISPR; CRISPR-Cas; virus defense; bacteria; bacteriophage; adaptation; spacer integration; interference; gene silencing; fluorescent reporter; Escherichia coli; Mikrobiologi; Microbiology;

    Abstract : CRISPR-Cas systems are adaptive immune systems in bacteria and archaea, consisting of a clustered regularly interspaced short palindromic repeats (CRISPR) array and CRISPR associated (Cas) proteins. In this work, the type I-E CRISPR-Cas system of Escherichia coli was studied.CRISPR-Cas immunity is divided into three stages. READ MORE

  6. 14. Twin-arginine translocation in Yersinia : the substrates and their role in virulence

    Author : Ummehan Avican; Åke Forsberg; Åsa Sjöling; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Yersinia pseudotuberculosis; Tat; virulence; Tat substrates; SufI; stress response; metabolism; infection; transcriptome analysis; Infectious Diseases; infektionssjukdomar; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Abstract : Pathogenic Yersinia cause a manifold of diseases in humans ranging from mild gastroenteritis (Y. pseudotuberculosis and Y. enterocolitica) to pneumonic and bubonic plague (Y. READ MORE

  7. 15. Evolution and host-specific adaptations of Legionella pneumophila

    Author : Anaísa B. Moreno; Lionel Guy; Dan I. Andersson; Fredrik Söderbom; Alexander W. Ensminger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolution; Legionella pneumophila; host-adaptation; experimental evolution; Acanthamoeba castellanii; transfection; Mikrobiologi; Microbiology;

    Abstract : How bacteria evolve pathogenic traits is shaped by their communities and environments. Legionella pneumophila is ubiquitous in aquatic habitats, where it persists by replicating within a broad range of protozoan hosts. Using the same mechanisms, L. READ MORE
