  1. 1. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Hampus Holmberg; [2023-06-22]
    Nyckelord :;

    Sammanfattning : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. LÄS MER

  3. 2. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Aubree Stephens; [2023]
    Nyckelord :methanogen; archaea; hydrogenotroph; halotolerant; Methanobacterium; Chimaera seep; methanogenesis;

    Sammanfattning : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. LÄS MER

  4. 3. Fodertillsatsen Bovaer® som metaninhibitor till mjölkkor. Med den aktiva substansen 3-nitrooxypropanol

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Vanessa Brodin; [2023]
    Nyckelord :mjölkko; metan; minska; reducera; 3-NOP; 3-nitrooxypropanol; mjölkkvalitet; mjölkavkastning;

    Sammanfattning : Att minska metanutsläppen från världens mjölkkor ger möjligheten att minska jordbrukets klimatpåverkan. Kornas metanutsläpp från fodersmältningen ger en kraftigare värmande effekt på atmosfären än vad koldioxid gör då metan är ca 32 gånger så kraftfull. Eftersom metan är en kortlivad gas kan minskning av den visa snabba resultat. LÄS MER

  5. 4. Microbial diversity in Swedish breeds of sheep analysed by amplicon based sequencing

    Master-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

    Författare :Farzana Nazir; [2023]
    Nyckelord :Ruminants; Microbiome; NGS; Bioinformatics; Statistical Analysis; Metagenomics; Data Analysis;

    Sammanfattning : The gastrointestinal tract (GIT) of ruminants have divergent type of microbiome provides favourable environment for their growth. In many species, these microbiome considered as important source of assessing animal health & welfare. LÄS MER

  7. 5. Nourishing a growing population : overcoming the challenge of B12 deficiency in an increasingly vegetarian world

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Helen Olga Thompson; [2020]
    Nyckelord :vitamin B12; lactic acid fermentation; vegan diets; micronutrient deficiency; sustainability; legumes;

    Sammanfattning : Increasing numbers of people are eliminating animal products from their diet in response to environmental concerns, as well as for human health reasons and in recognition of animal rights. Vitamin B12, an essential nutrient produced exclusively by bacteria and archaea, is present in animal products but is generally absent from unfortified plant foods. LÄS MER
