Antimicrobial activity and characterization of biosynthesized silver nanoparticles from Anisochilus carnosus

Silver nanoparticles with size of ۶- ۵۷nm were synthesized by bioreduction method from Anisochilus carnosus aqueous and ethanolic extract. Biosynthesized nanoparticles showed maximum antimicrobial activity against K. pneumonia (۱۳±۱.۶۷mm), E.coli (۱۳±۱.۹۷mm) and B. subtilis (۱۳±۱.۰۷mm) followed by P. aeruginosa and minimum against S. aureus. The quantitative formation, characteristics and impurities of silver nanoparticles were studied using UV-Vis absorption spectroscopy, X-ray diffraction analysis, EDX spectrum, scanning electron microscopy (SEM) analysis. Based on this investigation these silver nanoparticles may be used in effluent treatment process for reducing the microbial load.
