Abstract

Maize, one of the most important cereal crops in Bangladesh, is severely contaminated by fumonisin, a carcinogenic secondary metabolite produced by Fusarium including Fusarium proliferatum. Biocontrol with Bacillus strains is an effective approach to controlling this F. proliferatum as Bacillus has proven antagonistic properties against this fungus. Therefore, the present study aimed to determine how native Bacillus strains can reduce fumonisin in maize cultivated in Bangladesh, where BDISO76MR (Bacillus subtilis) 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 F. proliferatum 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 Bacillus-based formulation might be a potential approach in mitigating fumonisin contamination in maize to ensure safe food and feed.

用根瘤芽孢杆菌进行种子预处理：减少收获前玉米中伏马菌素污染的明智策略

玉米是孟加拉国最重要的谷类作物之一，受到伏马菌素的严重污染，这是一种由镰刀菌（包括增殖镰刀菌）产生的致癌二级代谢产物。使用枯草芽孢杆菌菌株进行生物防治是控制增殖镰刀菌的有效方法，因为枯草芽孢杆菌已被证明具有对抗这种真菌的特性。因此，本研究旨在确定本地芽孢杆菌菌株如何减少孟加拉国种植的玉米中的烟曲霉毒素，其中 BDISO76MR（枯草芽孢杆菌）菌株在离体的玉米芯和田间条件下的植株中都表现出最高的功效。BDISO76MR 菌株通过抑制分生孢子的萌发和孢子的形成，可使脱落玉米棒中的烟曲霉毒素浓度比未经处理的对照组降低 98.52%，体外抑制率分别为 61.56% 和 77.01%。另一方面，用配制好的 BDISO76MR 对种子进行处理，与未处理的对照组相比，烟曲霉毒素污染减少了 97.27%，而植物体内球茎接种的烟曲霉毒素污染减少了 95.45%。这意味着以芽孢杆菌为基础的制剂可能是减轻玉米中伏马菌素污染以确保安全食品和饲料的一种潜在方法。

期刊介绍： Toxins (ISSN 2072-6651) is an international, peer-reviewed open access journal which provides an advanced forum for studies related to toxins and toxinology. It publishes reviews, regular research papers and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced.
