  1. 6. The Production and Characteristics of an Orange Fleshed Sweet Potato Yogurt

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ariam Kunfu; [2023]
    Nyckelord :Sweet potato; fermentation; Ghana; yogurt; L. bulgaricus; S. thermophilus; food technology and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Yogurt is an ancient food, used for a better preservation of milk. Milk gets fermented by Streptococcus thermophilicus and Lactobacillus bulgaricus (lactic acid bacteria, LAB) which converts the lactose present in the milk to lactic acid. These probiotics support the microbial population balance of the gastrointestinal tract. LÄS MER

  3. 7. The evolutionary origins of phagocytosis in microbial populations

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Alfred Leimar; [2022]
    Nyckelord :Theoretical ecology; phagocytosis; predation; adaptive dynamics;

    Sammanfattning : The emergence of the eukaryotic cell was one of the key events that paved the path to the vast variety of complex life visible all around us. A pivotal event in the process of eukaryogenesis was an endosymbiosis of two prokaryotic cells which in time resulted in the mitochondria. LÄS MER

  4. 8. Microbial ecosystem analysis of biochar-enriched soil in Kenya using microfluidic soil models

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Erik Karlsson; [2022]
    Nyckelord :Soil microbial ecosystem analysis; Microbe abundance; Microbe foraging; Biochar; Agriculture; Microfluidics; In-situ visualization; Kenya; SoilChip; Soil model; Minor Field Study; Technology and Engineering;

    Sammanfattning : Healthy soil is rich in diverse microbial life, and a healthy microbial ecosystem is crucial for any well-functioning agriculture. Soil microbes are essential for organic decomposition and nutrient recycling in the soil, which make nutrients available for agricultural crops. LÄS MER

  5. 9. Storage of poultry manure in containers : changes in physiochemical parameters and survival of intestinal bacteria

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

    Författare :Homayoon Davam; [2022]
    Nyckelord :Enterobacteriaceae; Salmonella; composting; straw; litter decontamination; chicken manure;

    Sammanfattning : High nutrient content of chicken litter has made it one of the best organic fertilizers for agricultural land. However, reusing poultry litter in agriculture can be associated with food-borne pathogens such as E.coli, Salmonella and Campylobacter. LÄS MER

  7. 10. Hur påverkas markorganismerna av jordbruksmetoden strukturkalkning?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Maria Gustavsson; [2021]
    Nyckelord :structural liming; agriculture; microorganisms; clay soil; respiration; earthworm population; Earth and Environmental Sciences;

    Sammanfattning : This field study was done to get an understanding of how the agricultural method called “structural liming” might affect soil organisms in a negative way. Soil organisms are crucial as they perform biological processes that improve good soil structure. This is important as it enables sustainable food production, today, and in the future. LÄS MER
