霉菌毒素的生物脱除方法及机理研究概述

霉菌毒素是霉菌的次级代谢产物,易污染食物与饲料,危及人畜健康。长期暴露在霉菌毒素中会导致肝肾损伤、癌变、畸形和免疫抑制等问题。霉菌毒素的脱除已成为研究热点,脱除方法分为物理法、化学法和生物法,其中生物法具有环境友好、特异降解、反应温和等特点,引起人们广泛关注。文章综述了国内外利用微生物脱除霉菌毒素的新进展,阐述了以微生物为手段对各种霉菌毒素的脱除效果、脱除/降解机理与特点,最后展望了生物脱毒法的未来研究方向。

Advances in biological removal of mycotoxins and its mechanism

Mycotoxins,which have been widely found in food and feed products,were secondary metabolite of fungi and harmful to human and livestock health.Long-term exposure to mycotoxins could lead to liver and kidney damage,canceration,malformation,and immunosuppression.Therefore,a variety of approaches had been explored to eliminate the impact of mycotoxins contamination,including physical,chemical and biological methods.Biological method has been attracting attention because it is environmentally friendly,specific in degradation and mild in reaction conditions.The progress was reviewed in removal of mycotoxins by microorganism.The effect,mechanism and characteristics of the removal of various mycotoxins were summarized,as well as the future research aspect of biological removal was prospected.
