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

    University essay from Lunds universitet/Bioteknik (master)

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

    Abstract : 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. READ MORE

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

    University essay from SLU/Department of Molecular Sciences

    Author : Lotta Jonasson; [2020]
    Keywords : mould; survey; consumer; food waste; mycotoxin;

    Abstract : 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. READ MORE

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

    University essay from SLU/Department of Molecular Sciences

    Author : Caroline Sandberg; [2019]
    Keywords : Rhodotorula babjevae; PEFA; postharvest pathogens; yeast; mold;

    Abstract : 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. READ MORE

  5. 4. A risk assessment of patulin in home-made apple must

    University essay from SLU/Dept. of Microbiology

    Author : Jenny Arnér; [2015]
    Keywords : Patulin; mycotoxin; apple; Penicillium expansum; risk assessment; exposure assessment; Sweden;

    Abstract : Patulin is a mycotoxin produced by several filamentous fungi, which has been the object of a number of surveys in recent decades, due to its frequent occurrence in apple products made from decayed fruit. The legislated limit in apple products is 50 µg/kg and a provisional maximum tolerable daily intake (PMTDI) of 0. READ MORE

  6. 5. Reducing patulin levels in apple juice by fermentation with Saccharomyces cerevisiae

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Oscar Håkansson; [2015]
    Keywords : patulin; Penicillium expansum; apple juice; fermentation; HPLC; Saccharomyces cerevisiae; yeast;

    Abstract : Patulin is a mycotoxin that can be found in many apple products all over the world. It has been well-known for many decades and is nowadays one of the most regulated mycotoxins in food. Today when fruit and vegetables are traded internationally more than ever before, the quality of the goods might fall victim for careless storage during logistics. READ MORE
