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.
In addition to their importance in the food industry, species of Penicillium and Aspergillus serve in the production of a number of biotechnologically produced enzymes and other macromolecules, such as gluconic, citric, and tartaric acids, as well as several pectinases, lipase, amylases, cellulases, and proteases.n addition to their importance in the food industry, species of Penicillium and Aspergillus serve in the production of a number of biotechnologically produced enzymes and other macromolecules, such as gluconic, citric, and tartaric acids, as well as several pectinases, lipase, amylases, cellulases, and proteases.
