  1. 1. Temporal and spatial variation in the community composition of lake bacterioplankton

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Eva S. Lindström; Uppsala universitet.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; bacterioplankton; freshwaters; 16S rDNA; DGGE; community composition; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; limnologi; Limnology;

    Sammanfattning : Bacterioplankton are among the smallest and most abundant organisms in lake ecosystems. Due to the lack of relevant methods, the taxonomic composition of bacterioplankton has been studied less thoroughly than that of larger organisms. LÄS MER

  2. 2. Effect of environmental factors on bacterioplankton community composition, diversity and functionality

    Detta är en avhandling från Växjö, Kalmar : Linnaeus University Press

    Författare :Johanna Sjöstedt; Linnéuniversitetet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mikrobiologi; Microbiology; Akvatisk ekologi; Aquatic Ecology; marine microbiology; bacterioplankton; community composition; diversity; functionality; environmental factors; disturbance; distribution;

    Sammanfattning : The ocean covers more than 70 % of the Earth surface and represents the largest ecosystem on Earth. Bacteria are an important part of the marine food web not only in remineralisation but also since they utilize dissolved organic matter (DOM) and make the energy available to higher trophic levels.

  3. 3. Substrate control of community composition and functional adaptation in marine bacterioplankton

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Julie Dinasquet; Linnéuniversitetet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mikrobiologi; Microbiology; Akvatisk ekologi; Aquatic Ecology; marine microbial ecology; bacterioplankton; community composition; functional adaptation; dissolved organic carbon; bottom-up and top down factors; ctenophore Mnemiopsis leidyi; food-webs; Southern-Ocean; Antarctica;

    Sammanfattning : A drop of sea-water is teeming with a million of bacteria, on which pelagic food-webs and biogeochemical cycles depend. These bacteria thrive on a wide range of dissolved organic carbon (DOC) compounds produced through biotic and abiotic processes. LÄS MER

  4. 4. Composition and dynamics of the bacterial community in aerobic granular sludge reactors

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Enikö Barbara Szabo; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; qPCR; sequencing batch reactors; microbial community composition; T-RFLP; functional groups; Illumina MiSeq; wastewater; aerobic granular sludge; nitrogen removal; population dynamics;

    Sammanfattning : The aerobic granular sludge (AGS) technology is probably the future standard for wastewater treatment, due to its low footprint and low energy consumption. Although achieving granulation is usually not a challenge anymore, our understanding of the community assembly during start-up, and of the microbial ecology of these reactors in general, is incomplete.

  5. 5. Bacterioplankton population dynamics in a changing ocean

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Markus V. Lindh; Linnéuniversitetet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine microbiology; ecology; bacterioplankton; community composition; diversity; seasonality; biogeography; bimodal; metapopulation; community functioning; climate change; environmental disturbance;

    Sammanfattning : Hälften av all fotosyntes på vår planet utförs av växtplankton. De producerar organiskt material som utgör grunden för näringskedjan i havet. LÄS MER
