Abstract:

Patulin is a toxic secondary metabolite fungal species. Fungal pathogen Penicillium expansum is a main patulin producer. It can enter into the food circulation channel following the fresh fruits and their processing products, and cause great harm to human health. Patulin has been widely concerned in various countries of the world. This paper briefly reviews the physicochemical property and toxicity of patulin; particularly focuses on the relevant genes involved in patulin biosynthetic pathway, research progress made in its biological control technology, and makes comments for future research on patulin as well.

Key words: patulin, toxicity, biosynthesis, biocontrol, fruit quality

摘要：

棒曲霉素（patulin）是一种病原菌的次生代谢物，扩展青霉Penicillium expansum是产生棒曲霉素的主要病原菌。棒曲霉素随新鲜水果及其加工产品进入食品流通，对人体产生极大危害，受到世界各国的广泛关注。主要阐述了棒曲霉素的理化性质及毒性作用，重点探讨了棒曲霉素生物合成途径中相关基因的功能，以及棒曲霉素生物控制技术的新进展，并评述了棒曲霉素未来的研究重点。
