  2. 2. Effects of temperature and terrestrial carbon on fish growth and pelagic food web efficiency

    University dissertation from Umeå : Umeå Universitet

    Author : Robert Lefébure; Umeå universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attack rates; Bacterial production; Climate change; Critical resource density; Growth rates; Microbial food web; Three-spined stickleback;

    Abstract : Both temperature and terrestrial dissolved organic carbon (TDOC) have strong impacts on aquatic food web dynamics and production. Temperature affects vital rates of all organisms and terrestrial carbon has been shown to alter the dynamics of phytoplankton and bacterial production and affect the trophic structure of planktonic food webs.

  3. 3. Allochthonous and autochthonous carbon sources of lake bacterioplankton

    University dissertation from Department of Ecology, Lund University

    Author : Emma Kritzberg; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marinbiologi; limnologi; akvatisk ekologi; aquatic ecology; marine biology; Hydrobiology; bacterial community composition; bacterial growth efficiency; bacterioplankton; carbon subsidy; dissolved organic carbon; limnology;

    Abstract : Popular Abstract in Swedish Pelagiska bakterier använder löst organiskt material som kol- och energikälla. Det lösta materialet kan ha sitt ursprung i intern (autokton) eller terrester (allokton) primärproduktion. Den här avhandlingen handlar om hur bakterier använder autoktont och alloktont producerat kol. READ MORE

  4. 4. The efficacy of bacterial viruses against multi-resistant Escherichia coli: from isolation to pharmacology

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Mohammadali Khan Mirzaei; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phage therapy; Multiresistant E. coli; Pharmacodynamics; Pharmacokinetics; Bacterial viruses; Genomic; proteomic; molekylärgenetik; Molecular Genetics;

    Abstract : The increase of multi-resistant bacteria highlights that the golden era of antibiotics is ending and that alternative treatmentsare urgently needed. Phages have been historically used to treat bacterial infections prior to the discovery of antibiotics and have gained renewed interest in the past decade. READ MORE

  5. 5. Structure and function of microbial communities in constructed wetlands - influence of environmental parameters and pesticides on denitrifying bacteria

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Susann Milenkovski; Lunds universitet.; Lund University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fungicide; concentration-response curves; nosZ; nirS; nirK; bacterial activity; denitrification; bacterial community composition; herbicide; insecticide;

    Abstract : This thesis addresses the interactions and relationships between natural aquatic bacterial communities, environmental parameters, anthropogenic chemicals and the denitrification pathway in the habitat of agricultural constructed wetlands. The main aim was to gain fundamental knowledge of the drivers behind the processes of the denitrification (i.e. READ MORE
