Maize, one of the most important cereal crops in Bangladesh, is severely contaminated by fumonisin, a carcinogenic secondary metabolite produced by including . Biocontrol with strains is an effective approach to controlling this as has proven antagonistic properties against this fungus. Therefore, the present study aimed to determine how native strains can reduce fumonisin in maize cultivated in Bangladesh, where BDISO76MR () strains showed the highest efficacy both in vitro in detached cob and in planta under field conditions. The BDISO76MR strain could reduce the fumonisin concentration in detached cob at 98.52% over untreated control, by inhibiting the conidia germination and spore formation of . at 61.56% and 77.01%, respectively in vitro. On the other hand, seed treatment with formulated BDISO76MR showed higher efficacy with a reduction of 97.27% fumonisin contamination compared to the in planta cob inoculation (95.45%) over untreated control. This implies that -based formulation might be a potential approach in mitigating fumonisin contamination in maize to ensure safe food and feed.
玉米是孟加拉国最重要的谷类作物之一，但它严重受到伏马菌素的污染，伏马菌素是一种由包括在内的真菌产生的致癌次生代谢物。利用 菌株进行生物防治是控制这种污染的有效方法，因为 已被证明对这种真菌具有拮抗作用。因此，本研究旨在确定孟加拉国种植的玉米中，如何通过本土 菌株来降低伏马菌素的含量，其中 BDISO76MR()菌株在离体玉米芯和田间条件下的体内试验中均表现出最高的功效。BDISO76MR 菌株可通过抑制 的分生孢子萌发和孢子形成，将离体玉米芯中的伏马菌素浓度降低 98.52%，分别在体外达到 61.56%和 77.01%。另一方面，与体内玉米芯接种（未处理对照的 95.45%）相比，用配方 BDISO76MR 处理种子可降低 97.27%的伏马菌素污染，效果更高。这意味着基于 的配方可能是减轻玉米伏马菌素污染以确保食品安全和饲料安全的一种潜在方法。
