中文摘要：伏马菌素B1（FB1）是全球玉米粒和玉米制品中最常见的霉菌毒素之一。微生物降解与转化有毒有机污染物的过程是一种前景很好的食品净化方法。某些担子菌，如杏鲍菇复合菌，包括几种重要的食用商品品种，能解多环有机化合物及一系列废物和污染物的毒。本文研究杏鲍菇，食用最多的蘑菇之一，对净化玉米中FB1的潜在作用。结果表明本研究可能是减少饲料供应链中该霉菌毒素的一种环境友好的方法。
外文摘要：Fumonisin B1 (FB1) is among the most common mycotoxins found in maize kernels and maize products worldwide. The microbiological process of detoxification and transformation of toxic organic pollutants is a promising method for foodstuffs decontamination. Some basidiomycetes, such as the Pleurotus eryngii species complex, include several important commercial edible varieties that can detoxify polycyclic organic compounds and a range of wastes and pollutants. We investigated the potential role of P. eryngii, one of the most consumed mushrooms, in the decontamination of FB1 in maize. In addition, selected antioxidant enzymes, (soluble peroxidase (POD), catalase (CAT) and ascorbate peroxidase), primarily involved in control of cell hydrogen peroxide levels, and lignin degradation, were analyzed, to evaluate their contributions to the molecular mechanisms of FB1 by P. eryngii. FB1 decontamination by P. eryngii and involvement of CAT and POD enzymes in the control of toxic decontamination levels of H2O2 were demonstrated. A consistent reduction of FB1 was observed at different incubation times. The average decrease levels of FB1, with respect to the control cultures, ranged from 45 to 61% (RSD < 15%). This study is a possible eco-friendly approach to reducing this mycotoxin in the feed supply chains.
