Isolation and Some Properties of the Enzyme That Transforms Eremofortin C to PR Toxin.
PR toxin and eremofortin C are secondary metabolites of Penicillium roqueforti. The chemical structures of these two compounds are closely related to each other and differ only by an aldehyde and an alcohol group at the C-12 position. In an effort to better understand the biosynthesis of PR toxin, we discovered the enzyme of P. roqueforti that is responsible for the transformation of eremoforti...
متن کاملProduction of penicillic acid and patulin by an atypical Penicillium roqueforti isolate.
Simultaneous production of penicillic acid and patulin by an atypical strain of Penicillium roqueforti isolated from cheddar cheese is reported. Mycotoxin production was confirmed by thin-layer and gas-liquid chromatography and by ultraviolet, infrared, and mass spectral analyses. Culture extracts were toxic to Bacillus megaterium and chicken embryos. Commercial strains of P. roqueoforti used i...
متن کاملAristolochene synthase. Isolation, characterization, and bacterial expression of a sesquiterpenoid biosynthetic gene (Ari1) from Penicillium roqueforti.
Aristolochene is the likely precursor of the sesquiterpenoid toxins produced by a number of filamentous fungi. One of these, PR-toxin, is produced by Penicillium roqueforti. We report here the isolation of a gene (Ari1) coding for the sesquiterpene cyclase, aristolochene synthase (AS), from P. roqueforti. Nucleotide sequence analysis of genomic and cDNA clones revealed that the Ari1 gene contai...
متن کاملChemical constituents of the fermentation broth of the marine-derived fungus Penicillium roqueforti.
BACKGROUND The filamentous fungus Penicillium roqueforti is a well-known multifunctional cell factory of high added-value biomolecules. AIMS The objective of this work was to carry out a detailed analysis of the metabolites present in the culture broth of a new marine-derived Penicillium roqueforti strain isolated in the Canary Islands, Spain. METHODS The fungal biomass production was carri...
متن کاملMycotoxins and other secondary metabolites produced in vitro by Penicillium paneum Frisvad and Penicillium roqueforti Thom isolated from baled grass silage in Ireland.
Secondary metabolites produced by Penicillium paneum and Penicillium roqueforti from baled grass silage were analyzed. A total of 157 isolates were investigated, comprising 78 P. paneum and 79 P. roqueforti isolates randomly selected from more than 900 colonies cultured from bales. The findings mostly agreed with the literature, although some metabolites were not consistently produced by either...
