Abstract

Abstract:

Mycotoxins are highly toxic metabolites produced by fungi. They can enter animals and humans through feed and food, leading to acute or chronic toxicity reactions, which pose serious health risks to both humans and animals. Traditional detoxification methods for mycotoxins, such as physical and chemical methods, often suffer from low efficiency and may result in the loss of nutritional components in feed or food. Laccase, a biocatalyst with broad catalytic activity, has been increasingly applied in the degradation of various compounds in recent years. Studies have shown that laccase can effectively degrade aflatoxin B₁ and zearalenone, exhibiting high degradation efficiency and producing safe degradation products. Therefore, applying laccase for the degradation of aflatoxin B₁ and zearalenone is an excellent choice. This paper summarizes the sources, structure, and catalytic characteristics of laccase, and reviews recent advances in the degradation of mycotoxins such as aflatoxin B₁ and zearalenone by laccase. Aiming to provide theoretical support and reference for the more efficient, safe, and environmentally friendly application of laccase in the field of mycotoxin degradation.

Key words: mycotoxins, laccase, aflatoxins (AFs), zearalenone (ZEN)
