Fusarium infections result in reduced maize grain ( Zea mays L.) yields and notable impacts on human and animal health. Research involving natural products to control fungi in food is a promising alternative. Combinations of α-bisabolol (AB) and sodium chloride (NaCl) may suggest the use of lower effective concentrations of the drugs. This study aimed to evaluate the antifungal potential of AB associated with NaCl against Fusarium oxysporum strains isolated from maize. Minimum inhibitory concentrations (MICs) values of AB and NaCl were determined by microdilution, and an association study was performed (checkerboard). Effects on fungal mycelial growth (poisoned substrate technique) and a maize grain contamination model were analyzed. AB presented MIC values ranging from 128 and 1024 μg/mL; NaCl inhibited fungal growth at 16,384 μg/mL. The AB/NaCl association study revealed synergism by decreasing inhibitory concentrations by eight times. In corn kernels, AB and NaCl, whether isolated (at MIC) or in association (at sub-inhibitory concentrations), significantly inhibited in vitro mycelial growth ( P < 0.05). Further analysis of liquid from a canned maize sample also revealed the fungistatic effects of the compounds associations ( P < 0.05). The results confirm the antifungal potential of AB, whether isolated or in association with NaCl to control F. oxysporum in maize. Graphic Abstract

评估 α-没药醇与 NaCl 结合对玉米粒尖孢镰刀菌的抗真菌活性

镰刀菌感染导致玉米粒 (Zea mays L.) 产量减少,并对人类和动物健康产生显着影响。涉及控制食品中真菌的天然产品的研究是一个很有前途的替代方案。α-没药醇 (AB) 和氯化钠 (NaCl) 的组合可能表明使用较低有效浓度的药物。本研究旨在评估与 NaCl 相关的 AB 对从玉米中分离的尖孢镰刀菌菌株的抗真菌潜力。AB 和 NaCl 的最低抑菌浓度 (MIC) 值通过微量稀释确定,并进行关联研究(棋盘格)。分析了对真菌菌丝体生长(中毒基质技术)和玉米粒污染模型的影响。AB 呈现的 MIC 值范围为 128 和 1024 μg/mL;NaCl 在 16,384 μg/mL 时抑制真菌生长。AB/NaCl 关联研究通过将抑制浓度降低八倍而显示出协同作用。在玉米粒中,AB 和 NaCl,无论是分离的(MIC)还是联合的(亚抑制浓度),都显着抑制了体外菌丝体生长( P < 0.05)。对来自罐装玉米样品的液体的进一步分析也揭示了化合物组合的抑真菌作用 ( P < 0.05)。结果证实了 AB 的抗真菌潜力,无论是分离的还是与 NaCl 结合使用,以控制玉米中的尖孢镰刀菌。图形摘要 对来自罐装玉米样品的液体的进一步分析也揭示了化合物组合的抑真菌作用 ( P < 0.05)。结果证实了 AB 的抗真菌潜力,无论是分离的还是与 NaCl 结合使用,以控制玉米中的尖孢镰刀菌。图形摘要 对来自罐装玉米样品的液体的进一步分析也揭示了化合物组合的抑真菌作用 ( P < 0.05)。结果证实了 AB 的抗真菌潜力,无论是分离的还是与 NaCl 结合使用,以控制玉米中的尖孢镰刀菌。图形摘要
