Production 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 کاملMolecular cloning and functional characterization of two CYP619 cytochrome P450s involved in biosynthesis of patulin in Aspergillus clavatus.
Patulin is an acetate-derived tetraketide mycotoxin produced by several fungal species, especially Aspergillus, Penicillium and Byssochlamys species. The health risks due to patulin consumption by humans have led many countries to regulate it in human food. Previous studies have shown the involvement of cytochrome P450 monooxygenases in the hydroxylation of two precursors of patulin, m-cresol a...
متن کاملProduction 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 کاملIntracellular Biosynthesis of Gold Nanoparticles by the Fungus Penicillium Chrysogenum
In this study, the biosynthesis of gold nanoparticles by Penicillium chrysogenum, isolated from Ahar copper mine, was investigated. The gold nanoparticles were synthesized by reducing the aqueous gold ions using the culture supernatant of the filamentous fungi. The UV–vis spectrum displayed a characteristic peak at 532 nm that is very specific for gold nanoparticles. The XRD spectrum confirmed ...
متن کاملThe biosynthesis of 6-methylsalicylic acid. Crude enzyme systems from early and late producing strains of Penicillium patulum.
Two strains of Penicillium pafulum have been isolated from cultures of NRRL 21598. One produces 6-methylsalicyclic acid (MSA) very soon after transfer of mycelium from a germinating medium to Czapek-Dox medium and is designated an early MSA strain. In the other, 6-methylsalicyclic acid production begins only after 24 to 36 hours on Czapek-Dox medium, and it is designated a late MSA strain. Cell...
