Scientists discovered that a mushroom called Trametes hirsuta produces a special enzyme that can break down aflatoxin B1, a dangerous toxin that contaminates foods like peanuts, corn, and nuts. This enzyme is unique because it works without needing additional chemicals as helpers, making it practical for real-world use. The enzyme successfully degraded 77.9% of the toxin under simple conditions, and researchers suggest it could be applied directly to contaminated food surfaces as a safe, natural way to reduce food poisoning risks.
