人们越来越关注常规杀菌剂对人类健康和环境的影响,再加上不断升级的微生物抗性挑战,推动了对植物病原体的可持续生物防治策略的探索。这项研究报告,第一次,一种新型的绿色合成和表征,环保纳米材料,杏鲍菇-卵磷脂-壳聚糖纳米材料(PEELCN),来源于杏树提取物(PEE),卵磷脂(L),和壳聚糖(C)。PEELCN的结构属性使用傅里叶变换红外光谱(FTIR)阐明,扫描电子显微镜(SEM),热重分析(TGA),X射线衍射(XRD)和zeta电位测量,证实了稳定和均匀的纳米结构的成功形成。PEELCN的抗真菌活性,PEE,对五种经济上重要的植物病原真菌进行了评估:交替菌,大丽花黄萎病菌,双极星索罗基尼亚,和尖孢镰刀菌.PEE和PEELCN均对大丽花的菌丝生长表现出明显的抑制作用,B.Sorokiniana,还有N.dimudiatum,具有不同程度的功效。不同的抗真菌活性表明了物种特异性的作用模式。这些发现凸显了PEELCN作为可持续发展的潜力,生物相容性和具有成本效益的纳米杀菌剂用于植物病害的管理,具有发展成为可持续农业商业上可行的生物杀菌剂的潜力。
Growing concerns over the human health and environmental impacts of conventional fungicides, coupled with the escalating challenge of microbial resistance, have fueled the search for sustainable biocontrol strategies against plant pathogens. This study reports, for the first time, the green synthesis and characterization of a novel, eco-friendly nanomaterial, designated Pleurotus eryngii-Lecithin-Chitosan Nanomaterial (PEELCN), derived from P. eryngii extract (PEE), lecithin (L), and chitosan (C). The structural attributes of PEELCN were elucidated using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), X-ray Diffraction (XRD), and zeta potential measurements, confirming the successful formation of a stable and uniform nanostructure. The antifungal activity of PEELCN, and PEE, was assessed against five economically important phytopathogenic fungi: Neoscytalidium dimidiatum, Alternaria alternata, Verticillium dahliae, Bipolaris sorokiniana, and Fusarium oxysporum. Both PEE and PEELCN exhibited significant inhibitory effects on the mycelial growth of V. dahliae, B. sorokiniana, and N. dimidiatum, with varying degrees of efficacy. The differential antifungal activity suggests a species-specific mode of action. The findings highlight the promising potential of PEELCN as a sustainable, biocompatible, and cost-effective nanofungicide for the management of plant diseases, with the potential for development into a commercially viable biofungicide for sustainable agriculture.
