“Green Synthesis of Sulphur Nanoparticles via Psidium Guajava Leaf Aqueous Extract and Study of their Antimicrobial Activity and Antifungal activity.’’

Abstract

Abstract Now a day’s researchers focus on medicinal plant parts which used to synthesize metallic or metal oxide nanoparticles by a green route. This green technique was used for synthesis of sulphur nanoparticles by biologically reducing sodium thiosulphate pentahydrate and citric acid with aqueous leaf extract of Psidium gujava. These synthesized Sulphur nanoparticles are characterized by UV visible Spectrophotometer, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electronic microscopy and high-resolution transmission electron microscopy. The aqueous extract of leaves of Psidium gujava acts as capping and stabilizing agents for the synthesize. These biologically synthesized sulphur nanoparticles were tested for antimicrobial activity against E. coli and Bacillus subtilis bacteria.by Agar well diffusion method and Antifungal activity against Candida albicans by Agar well diffusion method.
