Utilisation of Green Synthesised Silver Nanoparticles for Water Quality Management

Abstract

In the present study silver nanoparticles (AgNPs) were synthesized using leaves of bamboo plant, Bambus vulgaris and the size of the nanoparticles was confirmed using XRD, EDAX, SEM, TEM, PSA analysis. The antimicrobial activity of the synthesized NPs showed a good antibacterial activity against the waterborne isolates, E. coli, Staphyllococcus aureus, Vibrio cholera and Salmonella sp. Further the anti algal activity of the NPs was tested against the algae, Dictyosphaerium pulchellum, and Algoriphagus chordate. The SEM studies revealed that the AgNPs breaks the cell wall of algae and inhibits the growth. The safe dose of AgNPs can be used in aquaculture farms, household water tanks and other small water bodies to wipe out waterborne pathogens and algal bloom.
