title: Production of penicillic acid and patulin by an atypical Penicillium roqueforti isolate.
abstract: 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 in production of blue-veined cheeses were shown not to produce penicillic acid and patulin.
