Production of patulin by Penicillium expansum.
Twenty-seven isolates of Penicillium expansum Lk. ex Thom obtained from Europe, Australia, and North America from seven different fruit hosts all produced patulin in culture. Six isolates were essentially nonpathogenic in apple fruits. In culture, patulin generally accumulated to much higher levels than in apple fruits. At all temperatures permitting fungus growth, patulin was produced. However...
متن کاملPatulin production in apples decayed by Penicillium expansum.
Sixty isolates of Penicillium expansum were tested for patulin production in decaying apples. All the isolates were found to produce the mycotoxin patulin as determined by thin-layer chromatography. Since patulin is known to be stable in many apple products, the results indicate that apple products made partially from apples decayed by P. expansum will contain patulin which may present a health...
متن کاملPatulin Accumulation In Apples During Storage by Penicillium Expansum and Penicillium Griseofulvum Strains
A part of apples destined to juice production is generally of poor quality. Apples from cold storage or recently harvest (ground harvested or low quality apples) are stored under ambient conditions until they are processed. Since Penicillium expansum and P. griseofulvum are the principal fungal species isolated from stored apples in Brazil, the objective of this study was to investigate the abi...
متن کاملIdentification of some secondary metabolites produced by four Penicillium species
Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...
متن کاملProduciton and biological activity of patulin and citrinin from Penicillium expansum.
Penicillium expansum isolated from meat and apples produced both patulin and citrinin. Toxin identity was confirmed by spectroscopic and physical methods. The mean lethal dose in chicken embryos was determined for toxins administered both singly and in various ratios. Data from simultaneous administration of mycotoxin combinations plotted as isobolograms showed and additive effect. Both toxins ...
