  1. 1. Early-life gut microbiota and breast milk oligosaccharides in relation to childhood immune maturation and allergy

    Detta är en avhandling från Stockholm : Wenner-Gren Institute for Experimental Biology, Stockholm University

    Författare :Ylva Margareta Sjögren; Stockholms universitet.; [2009]

    Sammanfattning : Atopic allergy is the most common chronic disease among children in the developed world. This high prevalence could be associated with low microbial exposure. The early gut microbiota appears to be important for immune maturation. LÄS MER

  2. 2. Evolution of symbiotic lineages and the origin of new traits

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Daniel Tamarit; Uppsala universitet.; [2016]

    Sammanfattning : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. LÄS MER

  3. 3. Prebiotic Oligosaccharides from Xylan: Heat Pretreatment, Xylanase Hydrolysis, Utilization by Potential Probiotics and Evaluation in a Mouse Study

    Detta är en avhandling från Chemistry Division of Biotechnology

    Författare :Peter Falck; Lunds universitet.; Lund University.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; arabinoxylan; xylooligosaccharides; arabinoxylooligosaccharides; Bifidobacterium; Lactobacillus;

    Sammanfattning : Modulation of the gut microbiota with prebiotic oligosaccharides from partially hydrolyzed xylans can be part of the solution for reducing the occurrence of many health problems such as diabetes, cardiovascular disease and cancer. Prebiotics are carbohydrates that selectively stimulate health beneficial bacteria in the colon, restoring homeostasis to the gut environment. LÄS MER

  4. 4. Impact of Bifidobacterium longum and Lactobacillus acidophilus on the intestinal microflora and bioavailability of some food mutagens

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Immunology, Microbiology, Pathology and Infectious Diseases

    Författare :Kerstin Orrhage; Karolinska Institutet.; Karolinska Institutet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The gastrointestinal microflora is a complex ecological system, normally characterised by a flexible equilibrium. The most important role of the microflora, from the point of view of the host, is probably to act in colonisation resistance against exogenous, potentially pathogenic, microorganisms. LÄS MER

  5. 5. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

    Detta är en avhandling från Department of Chemistry, Lund University

    Författare :Evelina Kulcinskaja; Lunds universitet.; Lund University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

    Sammanfattning : Popular Abstract in Swedish Människan lever inte bara själv, utan tillsammans med en mängd bakterier som lever i kroppen. Större delen av dessa lever i tjocktarmen. Dessa organismer är viktiga för vår hälsa. De stimulerar immunförsvaret, sänker pH i tarmen och gör det ogynnsamt för sjukdomsframkallande bakterier att växa till. LÄS MER
