Abstract

Some filamentous fungi of the genera Aspergillus and Penicillium are of high impact for food safety due to their ability to produce a toxic secondary metabolite, ochratoxin A (OTA). OTA is well known for its carcinogenic, immunosuppressive and teratogenic properties. OTA has also been extensively documented as a contaminant of a wide variety of foods including cereals, green coffee, spices, nuts, dried fruits, beer, wine, grapes, and grape juice. Following, a literature review on OTA and existing knowledge of three main ochratoxigenic fungi (Aspergillus westerdijkiae, A. carbonarius and Penicillium verrucosum) the objectives of the present thesis were: i) to study the effect of different ecophysiological factors such as pH, aw, microstructu...
