Effect of Penicillium expansum culture conditions on patulin production.
Penicillium expansum strains grown on Capek-Dox liquid medium excreted patulin to the medium. Its amount increased until day 12, then smaller amounts of the toxin were observed. Maximum patulin excretion took place at 25 degrees C, pH 6, although at 5 degrees C, pH 3 the presence of this mycotoxin was also observed. The highest amount of patulin produced was observed in medium containing fructose.
