The Penicillium genus, known for the antibiotic penicillin, plays a vital role in ecosystems, food production, and biotechnology. While it aids in nutrient recycling and enhances food flavors, it can also cause allergies and produce mycotoxins. Understanding its benefits and managing its risks are essential for health and industry.
