Streptomyces chiangmaiensis SSUT88A mediated green synthesis of silver nanoparticles: characterization and evaluation of antibacterial action against clinical drug-resistant strains.

ABSTRACT: This study involved the characterization of AgNPs synthesized from soil isolate Streptomyces sp. SSUT88A and their antimicrobial activities. The strain SSUT88A revealed 98.8% similarity of the 16s rRNA gene to Streptomyces chiangmaiensis TA4-1^T. The AgNPs were synthesized by mixing either intracellular or extracellular cell-free supernatant of strain SSUT88A with AgNO₃. The synthesized AgNPs from intracellular cell-free supernatant and extracellular cell-free supernatant were designated as IS-AgNPs and ES-AgNPs, respectively. The IS-AgNPs showed maximum absorbance of UV-vis spectra at 418 nm, while ES-AgNPs revealed maximum absorbance at 422 nm. The TEM observation of synthesized AgNPs revealed a spherical shape with an average diameter of 13.57 nm for I
