Production of penicillic acid and patulin by an atypical Penicillium roqueforti isolate.

摘要

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.
