赭曲霉毒素 (OTs) 是一种毒性极强的霉菌毒素,其中赭曲霉毒素 A (OTA) 是赭曲霉毒素家族中毒性最强且最普遍的一种。OTA 是受法律法规约束的五种最重要的霉菌毒素之一。动物和人类可能通过饮食摄入、吸入和皮肤接触接触 OTA。OTA 被认为具有肾毒性、遗传毒性、细胞毒性、致畸、致癌、致突变、免疫毒性和骨髓毒性。因此,摄入 OTA 污染的食物和饲料会影响动物的生产力和人类的健康。根据这篇综述,一些研究报告了为去除 OTA 而建立的方法。本综述重点介绍了减轻 OTA 污染的控制方法、OTA 生物解毒材料及其适用技术、用于 OTA 生物解毒的重组菌株、及其解毒效果、重组OTA降解酶及其来源、用于OTA、ZEN和AFB1霉菌毒素解毒的重组融合酶,以及目前应用和商业化的OTA生物解毒产品。然而,迄今为止,还没有一种技术被批准可以 100% 地对 OTA 进行解毒。由于重组降解酶和基因工程技术的效率和安全性,目前一些首选的 OTA 生物解毒策略是。因此,前瞻性研究应侧重于对来自具有巨大 OTA 解毒潜力的基因工程微生物菌株的纯酶进行标准化。以及目前应用和商业化的OTA生物解毒产品。然而,迄今为止,还没有一种技术被批准可以 100% 地对 OTA 进行解毒。由于重组降解酶和基因工程技术的效率和安全性,目前一些首选的 OTA 生物解毒策略是。因此,前瞻性研究应侧重于对来自具有巨大 OTA 解毒潜力的基因工程微生物菌株的纯酶进行标准化。以及目前应用和商业化的OTA生物解毒产品。然而,迄今为止,还没有一种技术被批准可以 100% 地对 OTA 进行解毒。由于重组降解酶和基因工程技术的效率和安全性,目前一些首选的 OTA 生物解毒策略是。因此,前瞻性研究应侧重于对来自具有巨大 OTA 解毒潜力的基因工程微生物菌株的纯酶进行标准化。

Research progress of ochratoxin a bio-detoxification
Ochratoxins (OTs) is an extremely toxic mycotoxin in which Ochratoxin A (OTA) is the most toxic and prevalent in the ochratoxin family. OTA is among the five most critical mycotoxins that are subject to legal regulations. Animals and humans may be exposed to OTA through dietary intake, inhalation, and dermal contact. OTA is considered nephrotoxic, genotoxic, cytotoxic, teratogenic, carcinogenic, mutagenic, immunotoxic, and myelotoxic. So, intake of OTA contaminated foods and feeds can impact the productivity of animals and health of people. According to this review, several studies have reported on the approaches that have been established for OTA removal. This review focused on the control approaches to mitigate OTA contamination, OTA bio-detoxification materials and their applicable techniques, recombinant strains for OTA bio-detoxification, and their detoxification effects, recombinant OTA-degrading enzymes and their sources, recombinant fusion enzymes for OTA, ZEN and AFB1 mycotoxins detoxification, as well as the current application and commercialized OTA bio-detoxification products. However, there is no single technique that has been approved to detoxify OTA by 100% to date. Some preferred current strategies for OTA bio-detoxification have been recombinant degrading enzymes and genetic engineering technology due to their efficiency and safety. Therefore, prospective studies should focus on standardizing pure enzymes from genetically engineered microbial strains that have great potential for OTA detoxification.
