Abstract: In this work, we synthesized blood orange peel extract-copper (II) (Cu2+) ions nanoflower (NFs) and blood orange juice extract-copper (II) (Cu2+) ions nanoflower examine their antimicrobial properties on the fish pathogen (Yersinia ruckeri). The main compounds of the blood orange peel extract and the blood orange juice extract were organic components, and the copper (II) (Cu2 +) ions were inorganic components. BOPE-Cu2 + nanoflowers are quite compact, porous, and uniform as compared to BOJE-Cu2+ nanoflowers. Scanning Electron Microscopy, Fourier Transform Infrared spectrometry, and Energy-Dispersive X-ray spectroscopy were used to observe the structures of the NFs. The findings of FT-IR show Cu-O and Cu-N bonds in NF, which may be an indicator of the development of NFs. Although the antimicrobial actions of BOPE-hNFs and BOJE-hNFs against Yersinia ruckeri (NCTC 12,268) have been confirmed.
