  1. 1. The importance of bacterial functional diversity for mixotrophic flagellate function

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Simon Wentritt; [2023]
    Nyckelord :Mixotrophs; Functional Diversity; Algae Culturing;

    Sammanfattning : This project examined the role of functional diversity of bacterial prey organisms on a mixotrophic flagellate’s function. The concept of functional diversity and its role for ecosystem functioning is a subject of ongoing research and controversially discussed. Mixotrophy is the combination of different modes of nutrition in one organism. LÄS MER

  3. 2. CO2 Sequestration by Bio-Accelerated Silicate Weathering

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Tora Uebel; Elisabeth Odelius; [2023]
    Nyckelord :enhanced silicate weathering; microorganisms; negative emission technology; CO2 emissions;

    Sammanfattning : Human-caused emissions of CO2 and other greenhouse gases are an established reason for the climate changes that affect planet Earth. Negative emission technologies (NETs), for example, bio-accelerated silicate weathering bioreactors, seek to capture and store carbon from the atmosphere. LÄS MER

  4. 3. Bio-enhanced silicate weathering : Coupled to sequestration of CO2

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Limnologi

    Författare :Marcus Westholm; [2022]
    Nyckelord :NETs; Bio-enhanced weathering; Carbon capture;

    Sammanfattning : Weathering of silicate minerals has long been a known source of natural CO2 sequestration, that could be increased in the presence of microorganisms. Bio-enhanced weathering of silicate minerals could increase the sequestration of CO2 from the atmosphere. LÄS MER

  5. 4. Microbial test organisms for sterilization processes in food industry

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Teknisk mikrobiologi

    Författare :Yasmin Nabila; [2018]
    Nyckelord :Aseptic processing and packaging; validation; test organisms; Aspergillus brasiliensis; Bacillus atrophaeus; Bacillus subtilis; sterilization; disinfection; applied microbiology; teknisk mikrobiologi; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : The importance of sterilization processes has been a major topic in the food manufacturing industry since it preserves the quality and provides longer shelf-life by preventing microbiological recontamination of products. Aseptic packaging is an alternative technique to pack commercially sterile products into containers with a very low recontamination rate, thus, the entire production chain must be designed according to the aseptic condition, including the packaging material, the filling machines, and the surrounding area where the process takes place.

  7. 5. An evaluation of the Bacillus content in beer

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

    Författare :Pierre Andersson; [2018]
    Nyckelord :Food technology; livsmedelsteknologi; Beer; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : The aim of this project was to investigate how Bacillus can survive in the finished beer. This was evaluated by producing batches of beer with starter cultures that were deemed to be interesting in terms of their Bacillus content. LÄS MER
