Abstract

Background

The growing awareness of the harmful effects of chemical fungicides resulted in the increasing demand for natural and sustainable alternatives for treatment of fungi-infected plants. This study focuses on the green biosynthesis of silver nanoparticles (AHNPs) using the aqueous extract from the nutshell of Arachis hypogaea, a common bio-waste.

Results

The synthesized green silver nanoparticles were characterized using UV–Vis spectroscopy, dynamic light scattering (DLS), zeta potential analysis, Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) analysis. The antifungal activity was analyzed by assessing the synthesized silver nanoparticles in two pathogenic strains of Aspergillus niger. The synthesized silver nanoparticles reduced the growth of Aspergillus niger strain 1 and 2 by 46.25% and 75.29%, respectively, at 100 µg/mL.

Conclusions

The study proves that the silver nanoparticles synthesized using Arachis hypogaea nutshell extract is effective in controlling the fungal pathogens. Further research will be carried out to analyze the antifungal activity in field condition and can be developed into nano-based fungicides for commercial applications. Nano-based fungicides are eco-friendly and can be tailor made to suit the farmers need to achieve sustainable agriculture.

以花生果壳提取物为原料合成的可持续环保银纳米颗粒，用于控制植物病原体

随着人们对化学杀菌剂有害影响的认识日益加深，对天然和可持续替代品的需求日益增加，以处理真菌感染的植物。本研究的重点是利用常见的生物废弃物花生果壳水提取物绿色合成纳米银（AHNPs）。结果利用紫外可见光谱（UV-Vis）、动态光散射（DLS）、zeta电位（zeta potential）、傅里叶红外光谱（FTIR）和x射线衍射（XRD）对合成的绿色纳米银进行了表征。通过测定合成的纳米银对两株黑曲霉的抑菌活性进行了分析。在100µg/mL浓度下，纳米银对黑曲霉菌株1和菌株2的生长抑制作用分别为46.25%和75.29%。结论以花生果提取物为原料制备的银纳米颗粒对真菌病原菌具有一定的防治作用。进一步的研究将在田间条件下分析其抗真菌活性，并可开发成纳米基杀菌剂用于商业应用。纳米杀菌剂是环保的，可以根据农民实现可持续农业的需要量身定制。图形抽象

期刊介绍： ESEU is an international journal, focusing primarily on Europe, with a broad scope covering all aspects of environmental sciences, including the main topic regulation. ESEU will discuss the entanglement between environmental sciences and regulation because, in recent years, there have been misunderstandings and even disagreement between stakeholders in these two areas. ESEU will help to improve the comprehension of issues between environmental sciences and regulation. ESEU will be an outlet from the German-speaking (DACH) countries to Europe and an inlet from Europe to the DACH countries regarding environmental sciences and regulation. Moreover, ESEU will facilitate the exchange of ideas and interaction between Europe and the DACH countries regarding environmental regulatory issues. Although Europe is at the center of ESEU, the journal will not exclude the rest of the world, because regulatory issues pertaining to environmental sciences can be fully seen only from a global perspective.
