ANTIMICROBIAL ACTIVITY OF BIO-WASTE MEDIATED ZINC OXIDE NANOPARTICLES AGAINST HUMAN PATHOGENS

Abstract

Fish waste management has been one of the major problems having the greatest impact on the environment.On the other side Zinc oxide nanoparticles are one of the most increasingly utilized nanomaterials in consumer products.The study aimed at a simple method for the green synthesis of Zinc oxide nanoparticles (ZnO) using aqueous extract of fish waste as a reducing and stabilizing agent.ZnO NPs were synthesized using the aqueous extract of fish waste within 3 hrs.The green synthesized ZnO NPs were characterized for size and structure using particle size analyzer and TEM respectively.Characterization data reveals that the particles were spherical shaped with an average size of 86.84 nm.The antimicrobial activity tested against Staphylococcus aureus and Escherichia coli were significant with zone of inhibition 11.75 and 10.05 at 50(µg/ml).Thus, the study provides an alternative approach for fish waste management.
