Synthesis of Silver nanoparticles using bioactive seaweeds against poultry pathogens

Abstract

Abstract There is an increasing demand to create nanomaterials that are eco-friendly, non-toxic, and less expensive in relation to human health. In order to investigate the effectiveness of the marine macro algae silver nanoparticles against two specific poultry bacterial infections, methanol extracts of Halimeda macroloba (green), Turbinaria conoides (brown), and Spyridia filamentosa (red) were used. The zone of inhibition against the two bacterial pathogens as well as AgNO3 as a control increases with an increase in the concentration of marine macro algae synthesized nanoparticles. The characterization by UV, FTIR, XRD, SEM and EDAX reveals the formation of silver nanoparticle through seaweeds and the LCMS data reveals the presence of bioactive compounds which exhibit antibacterial activity. Thus the chemical compounds such as phyllophenone and phorbasterone present in the marine macro algae may be responsible for the antibacterial action of poultry pathogens such as Staphylococcus aureus and Salmonella typhi according to LC-MS characterizations.
