摘要

银纳米粒子的生物合成(AgNPs)一直是一个研究领域，以避免在其合成中使用的有毒化学品对我们的健康和环境的有害影响。本研究利用从土壤中分离的一株铜绿假单胞菌rtac 11合成AgNPs。对合成的纳米颗粒进行表征，如紫外可见光谱，通过420 nm的特征峰证实了AgNPs的合成。傅里叶变换红外(FTIR)光谱分析揭示了AgNPs被蛋白质通过特征官能团封盖。利用扫描电子显微镜(SEM)证实了颗粒的纳米尺寸。AgNPs对大肠杆菌ATCC 8739和金黄色葡萄球菌ATCC 6538具有良好的抑菌活性，是一种优良的抗菌剂。

Synthesis, Characterization, and Biological Evaluation of Novel Pseudomonas aeruginosa RTAC 11 Synthesized Ag Nanoparticles

Biological synthesis of silver nanoparticles (AgNPs) has been an area of research to avoid the harmful effects of the toxic chemicals used in its synthesis on our health and environment. In the present study, a novel strain of Pseudomonas aeruginosa-RTAC 11 isolated from soil was used for the synthesis of AgNPs. Characterization of the synthesized nanoparticles like UV-vis spectroscopy confirmed the synthesis of AgNPs through a signature peak at 420 nm. Fourier Transform Infrared (FTIR) spectroscopic analysis revealed the capping of AgNPs by proteins through signature functional groups. The nano-size of the particles were confirmed using scanning electron microscopy (SEM). The AgNPs showed good antibacterial activity against Escherichia coli ATCC 8739 and Staphylococcus aureus ATCC 6538, thus indicating an excellent antibacterial agent.
