Phyto-fabrication of selenium nanorods using extract of pomegranate rind wastes and their potentialities for inhibiting fish-borne pathogens

Abstract The invasion of fish/seafoods by zoonotic pathogens causes health threats to humans. Plant derivatives and phytosynthesized nanometals could promisingly overcome bacterial infections/contaminations. extract pomegranate rinds (PRE) was innovatively employed for biosynthesizing selenium nanorods (Se-NRs). These agents were assessed as antibacterial candidates against diverse fish-borne pathogenic species ( Staphylococcus aureus , Pseudomonas aeruginosa Escherichia coli Salmonella typhimurium Sphingomonas paucimobilis ). PRE-synthesized Se-NRs, within 60 min contact, negatively charged (‒32 mV) had mean diameter 62.31 nm length range 443.5–1236.9 nm. designated infrared spectra PRE PRE/Se-NRs composite validated the biosynthesis, bonding, interactions nanocomposite. potentialities PRE, confirmed toward entire challenged pathogens; S. highest resistance (with inhibitory concentrations 72.5, 60.0, 55.0 mg/L, respectively) S . most sensitive 55.0, 45.0, 42.5 respectively). ultrastructure treated with emphasized potentiality deforming/distorting cells 4 h causing full cells’ destruction deformation 8 exposure. PRE-phytosynthesized Se-NRs are advocated potent products decontaminating fisheries farms products.
