摘要:

玉米赤霉烯酮(ZEN)及其衍生物是全球危害最严重的真菌毒素之一, 严重威胁粮食安全和人类健康。ZEN的生物降解技术开发一直是研究的热点。其中酶降解法因其特异性和有效性受到了广泛关注, ZEN降解酶主要包括漆酶、锰过氧化物酶和内酯水解酶。相较于前两类酶, 内酯水解酶因其高活性、降解机制清晰且降解产物无毒等优点, 使其具有ZEN脱毒酶制剂开发潜力。但天然酶在工业生产条件下的稳定性较差, 难以满足产品制备和实际应用的要求。通过理性或半理性设计等优化手段提升天然酶的活性和稳定性是目前的热点研究方向。本文综述了微生物源ZEN内酯水解酶的基因挖掘、特性表征、分子改造手段及其应用, 旨在阐明生物脱毒法在工业生产和畜牧业应用中的优势与挑战, 为开发高活性、高稳定性ZEN脱毒酶制剂提供新思路。

Abstract:

Zearalenone (ZEN) and its derivatives rank among the most hazardous mycotoxins worldwide, posing a significant threat to food safety and public health. Consequently, the development of efficient biodegradation strategies for ZEN has emerged as a critical research priority. Among these, enzymatic degradation approaches have garnered considerable attention due to their specificity and efficacy.ZEN-degrading enzymes primarily include laccases, manganese peroxidases, and lactonases. Compared to the first two enzyme classes, lactonases exhibit distinct advantages for the development of ZEN detoxification agents, including higher catalytic activity, well-defined degradation mechanisms, and non-toxic degradation byproducts. However, natural enzymes often suffer from limited stability under industrial processing conditions, hindering their applicability in large-scale production and practical settings. To address this challenge, enhancing enzyme activity and stability through rational or semi-rational design and optimization has become a key research focus.This review comprehensively examines microbial-derived ZEN lactonases, covering gene mining, biochemical characterization, molecular engineering, and practical applications. By evaluating the advantages and limitations of biological detoxification in industrial and livestock production, this analysis provides novel insights for the development of highly active, robust ZEN-detoxifying enzyme preparations.

Key words: zearalenone, lactonase, rational design, enzyme activity stability, stability optimization, toxin degradation
