Bacterial indoleacetic acid-induced synthesis of colloidal Ag2O nanocrystals and their biological activities
The biosynthesis and biological activity of colloidal Ag 2 O nanocrystals have not been well studied, although they have potential applications in many fields. For the first time, we developed a reducing agent free, cost-effective technique for Ag 2 O biosynthesis using Xanthomonas sp. P5. The optim...

2
O nanocrystals have not been well studied, although they have potential applications in many fields. For the first time, we developed a reducing agent free, cost-effective technique for Ag
2
O biosynthesis using
Xanthomonas
sp. P5. The optimal conditions for Ag
2
O synthesis were 50 °C, pH 8, and 2.5 mM AgNO
3
. Using these conditions the yield of Ag
2
O obtained at 10 h was about five times higher than that obtained at 12 h under unoptimized conditions. Ag
2
O was characterized by FESEM-EDS, TEM, dynamic light scattering, XRD, and UV–Visible spectroscopy. Indoleacetic acid produced by the strain P2 was involved in the synthesis of Ag
2
O. Ag
2
O exhibited a broad antimicrobial spectrum against several human pathogens. Furthermore, Ag
2
O exhibited 1,1-diphenyl-2-picrylhydrazyl (IC
50
= 25.1 µg/ml) and 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonate (IC
50
= 16.8 µg/ml) radical scavenging activities, and inhibited collagenase (IC
50
= 27.9 mg/ml). Cytotoxicity of Ag
2
O was tested in fibroblast cells and found to be non-toxic, demonstrating biocompatibility. |
