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

    Författare :Enikö Barbara Szabo; Chalmers tekniska högskola; []
    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.

  3. 2. Microbial community dynamics in the phyllosphere of leafy vegetables

    Författare :Julia Darlison; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Microbes interact with the phyllosphere creating a plant microbiota holobiont. From a food safety aspect the phyllosphere is especially important in leafy vegetables which are generally consumed raw. Plant-microbe interactions are complex, but well-known ecological concepts can be applied to explain the dynamics. LÄS MER

  4. 3. Single cell protein in fish feed: effects on gut microbiota

    Författare :Andreas Nyman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The microbiota has been shown to be important for nutrition and health. It provides the host with an extensive arsenal of dietary enzymes that can contribute to host metabolism by conversion of otherwise undigestible compounds to metabolites that the host can utilize. LÄS MER

  5. 4. Colostrum quality, intestinal microbiota and implications for health in young dairy calves

    Författare :Bui Phan Thu Hang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The early life of calves in southern Vietnam and in Sweden were studied in this thesis, with the focus on colostrum quality, gut microbial communities and antimicrobialresistant Escherichia coli. The first of four studies showed that most cows on smallholder farms in Vietnam produced colostrum of good quality and that only around 10% of calves suffered from failure of passive immune transfer.

  7. 5. Avian MHC : Characterization and expression patterns of classical and non-classical MHC-I genes

    Författare :Anna Drews; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MCH class I; Classical genes; Non-classical genes; Expression; Passerine birds;

    Sammanfattning : The function of the vertebrate immune system is to enable recognition and elimination of microorganisms that can cause harm (pathogens). A key component in adaptive immunity is the major histocompatibility complex (MHC) that codes for molecules with antigen presentation function. LÄS MER
