  1. 1. Microbial life deep underground : From anaerobic cultures to reconstructed genomes

    Författare :George Westmeijer; Mark Dopson; Hans Røy; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Continental deep biosphere; microbial ecology; anaerobic enrichment cultures; Candidatus Desulforudis audaxviator; Thiobacillus denitrificans; flow-cells; Mikrobiologi; Microbiology; Ecology; Ekologi;

    Sammanfattning : The deep biosphere refers to the vast ecosystem of life beneath the Earth’s surface, residing in the fractured bedrock and pores of rocks, largely isolated from solar energy. These fractures enclose an important reservoir of groundwater that contains microorganisms active in processes such as the uptake of inorganic carbon, sulfur cycling, or the degradation of organic matter.

  3. 2. The Cyanobacterial Uptake Hydrogenase : Regulation, Maturation and Function

    Författare :Marie Holmqvist; Peter Lindblad; Karin Stensjö; Kornél Kovács; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biohydrogen; CalA; Cyanobacteria; Hydrogenase; Maturation; Nostoc punctiforme ATCC 29133; Nostoc sp. PCC 7120; Transcriptional regulation; Molecular biology; Molekylärbiologi; Molecular biology; Molekylärbiologi; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : With accellerating global warming and pollution problems a change of energy regime is necessary. Solar energy offers a clean and unlimited energy source of enormous potential. Due to it’s intermittenet nature solar energy must be stored - ideally in the chemical bond of a carrier molecule. LÄS MER

  4. 3. Feeding Lactobacillus paracasei ssp. paracasei strain F19 to infants during weaning : effects on adaptive immunity and gut microbial function

    Författare :Christina West; Olle Hernell; Marie-Louise Hammarström; Outi Vaarala; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adaptive immunity; allergy; complementary food; eczema; gut microbiota; infections; probiotics; short-chain fatty acids; Th1 Th2; weaning; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : Introduction: Gut microbial composition has been associated with immune-mediated diseases. Breastfeeding yields a microbiota rich in bifidobacteria and promotes colonization by lactobacilli. Bifidobacteria and lactobacilli are considered health-promoting and are used as probiotics, i.e. LÄS MER

  5. 4. Plant and microbial xyloglucanases: Function, Structure and Phylogeny

    Författare :Jens Eklöf; Harry Brumer; Harry Gilbert; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; xyloglucan; xyloglucanases; XTH; XET; XEH; endoglucanases; EG16; Molecular biology; Molekylärbiologi;

    Sammanfattning : In this thesis, enzymes acting on the primary cell wall hemicellulose xyloglucan are studied.  Xyloglucans are ubiquitous in land plants which make them an important polysaccharide to utilise for microbes and a potentially interesting raw material for various industries.

  7. 5. Comparative analysis of pathogen occurrence in wastewater : management strategies for barrier function and microbial control

    Författare :Jakob Ottoson; Bengt Hultman; Roland Schertenleib; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; parasites; treatment; Water engineering; Vattenteknik;

    Sammanfattning : This project was initiated to fill knowledge gaps on the occurrence of pathogens in different streams of wastewater, e.g. greywater and domestic wastewater. LÄS MER
