Abstract

The research deals with the contamination of feeding crops with fungi, producing mycotoxins and use of selected yeasts for detoxification. The thin-layer chromatography and ELISA methods were applied for the analysis of fungal secondary metabolites. The results showed a high rate of the grain contamination with fungi, mainly from genera Penicillium, Fusarium, Aspergillus and Alternaria. Some of the fungal strains produced 6-9 toxic compounds. The novelty of the study was the application of the yeast strains in detoxification of aflatoxins, zearalenon and deoxynivalenol in feed.

摘要

该研究涉及产真菌毒素的真菌对饲料作物的污染以及使用特定酵母进行解毒。采用薄层色谱法和酶联免疫吸附测定法分析真菌次生代谢产物。结果表明，谷物受真菌污染的比例很高，主要来自青霉属、镰刀菌属、曲霉属和链格孢属。一些真菌菌株产生6 - 9种有毒化合物。该研究的新颖之处在于将酵母菌株应用于饲料中黄曲霉毒素、玉米赤霉烯酮和脱氧雪腐镰刀菌烯醇的解毒。
