A fermentation technique was utilised to assess a fungus, i.e. Cunninghamella bertholletiae/polymorpha, isolated from rotting cassava, ability to produce mycotoxins and resultant oxidation by-products of the mycotoxins using liquid chromatography–mass spectrometry (LC/MS). Thus, the mycotoxins/secondary metabolites, fumonisin B1 (FB1) and deoxynivalenol (DON) were produced while, heptadecanone, octadecanamide, octadecenal and 3-keto-deoxynivalenol (DON) were successfully identified as biodegradation by-products in the fermentation broth treated with hydrolysing ‘monkey cup’ juice from Nepenthes mirabilis. Exposure to the mycotoxins and the biodegradation by-products through consumption of contaminated produce including contact due to the cumulative presence in arable agricultural soil can be harmful to humans and animals. Therefore, this work reports on a strategy for the mitigation and reduction of mycotoxins in agricultural soil using natural plant pitcher juices from N. mirabilis’ ‘monkey cup’.
利用发酵技术，利用液相色谱-质谱(LC/MS)分析了从腐烂木薯中分离出来的真菌，即Cunninghamella bertholletiae/polymorpha，产生真菌毒素的能力以及真菌毒素的氧化副产物。因此，真菌毒素/次生代谢产物伏马菌素B1 (FB1)和脱氧雪腐镰刀菌素醇(DON)在水解液中产生，而十六烷酮、十八烷酰胺、十八烯醛和3-酮-脱氧雪腐镰刀菌素醇(DON)则被成功鉴定为生物降解副产物。通过食用受污染农产品而暴露于霉菌毒素和生物降解副产品，包括因其在耕地土壤中累积存在而接触，可能对人类和动物有害。因此，本工作报告了一种缓解和减少农业土壤中真菌毒素的策略，该策略使用了来自N. mirabilis ' ' monkey cup ' '的天然植物水罐汁。
