  1. 1. Binuclear zinc transcription factors and the regulation of patulin biosynthesis in the filamentous Ascomycete Penicillium expansum

    Master-uppsats, Lunds universitet/Bioteknik (master)

    Författare :Robert Hansen Jagrelius; [2021]
    Nyckelord :secondary fungal metabolism; penicillium expansum; patulin; binuclear zinc transcription factors; dimerization; deepcoil; Biology and Life Sciences;

    Sammanfattning : This thesis investigated the regulation of patulin production in Penicillium expansum in relation to fungal global regulators as well as the cluster-specific binuclear zinc transcription factor (BZTF) patL in silico. It also explored the state of BZTF research in filamentous ascomycetes fungi, and questioned if results in Saccharomyces cerevisiae can be freely translated to other taxonomic groups. LÄS MER

  3. 2. Scrape off or throw away? : consumer attitudes to mouldy foods at home

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Lotta Jonasson; [2020]
    Nyckelord :mould; survey; consumer; food waste; mycotoxin;

    Sammanfattning : Knowledge about how consumers handle mouldy food products at home is limited. It is of interest to investigate these aspects more closely, since some moulds can produce mycotoxins and other secondary metabolites that could be harmful to human health. LÄS MER

  4. 3. MALDI-TOF MS for identification of Aspergillus species : A pilot study preceding possible implementation of MALDI-TOF MS to complement morphological assessment

    Uppsats för yrkesexamina på grundnivå,

    Författare :Christel Lindström; [2020]
    Nyckelord :Filamentous fungi; matrix-assisted laser desorption ionization time-of-flight mass spectrometry; fungal identification; protein extraction; species complex;

    Sammanfattning : Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has revolutionized the field of bacterial diagnostics and is also used for routine analysis in smaller clinical laboratories. For identification of moulds, pre-analytical steps are more complicated and time consuming than for bacteria, and the choice of reference library has a big impact on the utility of MALDI-TOF MS.

  5. 4. Evaluation of the antagonistic activity of Rhodotorula babjevae and its extracellular compounds towards postharvest pathogens

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Caroline Sandberg; [2019]
    Nyckelord :Rhodotorula babjevae; PEFA; postharvest pathogens; yeast; mold;

    Sammanfattning : The growing population ultimately puts pressure on the food industry to become more effi-cient and to reduce postharvest food waste. The leading method of reducing postharvest decay of fruits has been through fungicide application. LÄS MER

  7. 5. Biopreservation effects with Wickerhamomyces anomalus after 2 months moist airtight storage of sorghum

    Kandidat-uppsats, SLU/Dept. of Microbiology

    Författare :Louise Nybogård; [2016]
    Nyckelord :wickerhamomyces anomalus; sorghum; storage; biocontrol; biopreservation; food loss;

    Sammanfattning : Today one third of all produced food is thrown away and one reason for this is microbial spoilage. Hunger and malnutrition in Africa could be reduced if the food loss is reduced. Wickerhamomyces anomalus is a possible biocontrol agent in food science that has shown antifungal and antibacterial effects on, for example, stored barley. LÄS MER
