Abstract

This study describes the biosynthesis of nickel nanoparticles (Ni NPs) using gram-negative bacterium, Enterobacter cloacae. The synthesized Ni NPs were annealed at 350 °C for 3 h and characterized using various techniques. Powder X-ray diffraction analysis revealed the formation of Ni NPs with an average crystallite size of 48.78 nm. UV-Vis spectroscopy exhibited an absorption peak at 394 nm, while FTIR confirmed a peak at 416 nm. Field emission scanning electron microscopy showed the Ni NPs as a mixture uniform distribution, characterized by almost uniform spherical or hexagonal shapes. The Ni NPs demonstrated moderate antibacterial activity but exhibited notably high biofilm activity against Pseudomonas aeruginosa species, suggesting their potential in combating biofilm-associated infections. Additionally, the biosynthesized Ni NPs showed promising larvicidal and Insecticidal activities. This study provides an eco-friendly and cost-effective method for synthesizing Ni NPs and highlights their multifaceted applications in healthcare and pest control.

利用阴沟肠杆菌生物合成纳米镍：表征和多方面的应用。

本研究描述了利用革兰氏阴性细菌阴沟肠杆菌合成镍纳米颗粒（Ni NPs）。将合成的Ni NPs在350℃下退火3 h，并采用各种技术对其进行表征。粉末x射线衍射分析显示形成的Ni NPs平均晶粒尺寸为48.78 nm。紫外可见光谱在394 nm处发现吸收峰，红外光谱在416 nm处发现吸收峰。场发射扫描电镜显示，Ni纳米粒子呈均匀的混合分布，呈均匀的球形或六边形。Ni NPs表现出中等的抗菌活性，但对铜绿假单胞菌表现出明显的高生物膜活性，表明它们在对抗生物膜相关感染方面具有潜力。此外，生物合成的Ni NPs具有良好的杀幼虫和杀虫活性。本研究提供了一种环保、经济的合成Ni NPs的方法，并强调了它们在医疗保健和害虫防治方面的多方面应用。

期刊介绍： How can the scientific knowledge we possess now influence that future? That is, the FUTURE of Earth and life − of humankind. Can we make choices in the present to change our future? How can 21st century biological research ask proper scientific questions and find solid answers? Addressing these questions is the main goal of Biologia Futura (formerly Acta Biologica Hungarica). In keeping with the name, the new mission is to focus on areas of biology where major advances are to be expected, areas of biology with strong inter-disciplinary connection and to provide new avenues for future research in biology. Biologia Futura aims to publish articles from all fields of biology.
