Abstract

Mushrooms have been used by people for centuries for various purposes due to their unique taste, high nutritional content and pharmacological effects. Bioactive components in the structure of mushrooms are an important biological source for the green synthesis of silver nanoparticles (AgNPs) as reducing and stabilizing agents. In this study, AgNPs/Ig were synthesized using the mushroom species Infundibulicybe gibba. The color transformation of the formed nanoparticles from yellow to brown occurred and peaked at 370 nm in the UV–Vis spectrum. The nanoparticles had amorphous shape and their molecular characterization was determined by Fourier transform infrared spectroscopy (FTIR). AgNPs/Ig was much more stable (− 50.02 mV) and its hydrodynamic diameter was much lower (216.50 nm) compared to the mushroom extract. A significant increase in the antioxidant activity (IC50 5.66 mg/ml) and thermal stability of the formed nanoparticles was determined. Lipid peroxidation inhibition of the extract and nanoparticles was measured as IC50 value of 6.75 and 5.51 mg/ml, respectively. In the antimicrobial analysis results, while the mushroom extract did not show any inhibition against the selected microorganisms, AgNPs/Ig showed a low antimicrobial activity. As a result, the synthesis of AgNPs/Ig was carried out through green synthesis, which is environmentally friendly, safe, cost-effective, easy to use and does not contain toxic chemicals, and it has been revealed that AgNPs synthesized using this mushroom species have advantageous potential for use.

长春藤提取物合成纳米银的抗氧化、抗菌和热稳定性评价
蘑菇因其独特的味道、高营养含量和药理作用,几个世纪以来一直被人们用于各种目的。蘑菇结构中的生物活性成分是绿色合成银纳米粒子(AgNPs)的重要生物来源,具有还原和稳定作用。本研究以蘑菇Infundibulicybe gibba为原料合成AgNPs/Ig。形成的纳米颗粒的颜色由黄色转变为棕色,并在紫外可见光谱370 nm处达到峰值。纳米颗粒呈无定形,并通过傅里叶变换红外光谱(FTIR)对其进行了分子表征。AgNPs/Ig稳定度为- 50.02 mV,水动力直径为216.50 nm。纳米颗粒的抗氧化活性显著提高(IC50为5.66 mg/ml),热稳定性显著提高。测定提取物和纳米颗粒对脂质过氧化的抑制作用,IC50值分别为6.75和5.51 mg/ml。在抗菌分析结果中,蘑菇提取物对所选微生物没有抑制作用,而AgNPs/Ig则表现出较低的抗菌活性。因此,AgNPs/Ig的合成通过绿色合成进行,具有环境友好、安全、成本低、使用方便、不含有毒化学物质等特点,揭示了利用该菌种合成的AgNPs具有良好的应用潜力。
