چکیده انگلیسی
Green synthesis of silver nanoparticle (SNPs) has gained considerable attention in nano-biotechnology and nano-medicine owing their potency and eco-friendliness. In this, we account the exopolysaccharide and its mediated synthesis of SNPs and their biological activities. Exopolysaccharide of the Streptomyces violaceus composed of total carbohydrate (61.4%), ash (16.1%), moisture content (1.8%) and NMR confirmed their structural composition. SNPs synthesized by the exopolysaccharide, confirmed using UV-vis spectral analysis and characterized by TEM and XRD analyses. Further, the SNPs evaluated for its antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis using disc diffusion method. The SNPs has shown promising antibacterial activity were evaluated for MIC. Furthermore, the SNPs were tested for antioxidant activities and was found to have promising antioxidant activity over the standards. The above results prove that SNPs can be considered as a potent antibacterial and antioxidant drug in future.
