Bacterial indoleacetic acid-induced synthesis of colloidal $ Ag_{2} $O nanocrystals and their biological activities
Abstract 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 Xanthomona...

| 520 | |a Abstract 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 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. | ||

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.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ag</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">O nanocolloids</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Antimicrobial activity</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Collagenase inhibition</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Indoleacetic acid</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">sp</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jang, Eun-Young</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jeong, Seong-Yun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hwang, Dae-Youn</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Son, Hong-Joo</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Bioprocess and biosystems engineering</subfield><subfield code="d">Springer Berlin Heidelberg, 2001</subfield><subfield code="g">42(2018), 3 vom: 17.

Bacterial indoleacetic acid-induced synthesis of colloidal $ Ag_{2} $O nanocrystals and their biological activities |
| abstract |
Abstract 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 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. © Springer-Verlag GmbH Germany, part of Springer Nature 2018 |
