Fruits and derived products contaminated by patulin are harmful to
human health. Exploring environmental factors that affect patulin production
and involve regulatingmechanismsmay provide help in developing
effective means for controlling this mycotoxin. In the present
study, the effects of 11 C sources, 11Nsources and pH 3.0–8.0 on patulin
biosynthesis were compared in three P. expansum strains. In addition
