Penicillium species are one of the most common causes of fungal spoilage in fruits and vegetables. Penicillium italicum and Penicillium digitatum are the most common attackers of citrus fruits, while Penicillium expansum is known to attack apples. P. digitatum works by producing ethylene to accelerate ripening.
The most common species include Penicillium chrysogenum (also known as P. notatum), Penicillium frequentans, Penicillium citrinum, Penicillium janthinellum, Penicillium marneffei, and Penicillium purpurogenum. Penicillium molds prefer damp and dark places, but can occur elsewhere.n a study of Penicillium species, IgE cross-reactivity among the major allergens of P. oxalicum and P. notatum and the 33 kDa major allergen of P. citrinum was detected by immunoblot inhibition studies.
