Mycophenolic acid (MPA) is an antibiotic and immunosuppressive drug produced by Penicillium strains as a secondary extracellular metabolite. In this work, the effect of some various concentrations of enzymatically hydrolyzed casein on mycophenolic acid yield and process productivity was studied. The first, a base medium was applied for mycophenolic acid production by Penicillium brevicompactum ...

The effect of the oregano extract (Origanum vulgare L.) on the growth of Fusarium and Penicillium species isolated from cakes and ready-for-use fresh salads from different kinds of vegetables was investigated. The contents of the active component of extract were identified by GC-MS and they include: carvacrol (34.2%), carvone (18.5%), p-cimene (8.05%), thymol (3.74%). The oregano extract showed...

(Received: May 11, 2011; June 13, 2011) Abstract: In the most cases of the practical fermentation processes with filamentous microorganisms, direct monitoring of the cell morphology and biomass distribution in the culture medium is not easily possible. Use of a mathematical model is a suitable way to describe the substrate uptake and cell growth behavior of these microorganisms. Penicillium bre...

The European Union (EU) has introduced statutory limits for patulin in fruit products. Species definitions need to be unambiguous for this capability, especially to determine 'weak spots' in food, drink and feed production. Fungi were analysed for the isoepoxydon dehydrogenase (IDH) gene of the patulin metabolic pathway to indicate potential patulin production. In several cases inhibition of PC...
