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 کاملThe effect of culture preservation techniques on patulin and citrinin production by Penicillium expansum Link.
AIMS To study the influence of culture preservation methods and culture conditions on the production of the mycotoxins patulin and citrinin by Penicillium expansum. METHODS AND RESULTS Ten strains of Penicillium expansum were preserved using subculture and maintenance at 4 degrees C, mineral oil, drying on silica gel and freeze-drying. Patulin and citrinin production was assessed on yeast ext...
متن کاملProduction of [14C]patulin by Penicillium patulum.
Factors affecting the production of [14C]patulin from [1-14C]acetate by replacement cultures of Penicillium patulum have been investigated. Incorporation of [1-14C]acetate into patulin reached a maximum with 6- to 8-day-old cultures incubated at 28 degrees C for 8 h in a replacement medium containing 0.1 M glucose, inorganic salts, and undiluted [1-14C]acetate. The specific activity of [14C]pat...
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...
