Developing sustainable approach for controlling foodborne pathogens, based on chlorella vulgaris extract/alginate nanoemulsion, and enhanced via the dispersed zinc oxide nanoparticles.

A promising antibacterial strategy was developed in this study to effectively eradicate foodborne pathogens via the synergism of Chlorella vulgaris extract (CVE) with zinc oxide nanoparticles (ZNPs) combined into a single nanoform. CVE-alginate nanoemulsion with enhanced antimicrobial and antioxidant properties via the dispersed ZNPs, were prepared and characterized using UV-Vis spectra, FE-SEM-EDX, TEM, DLS, FTIR. The CVE methanol extract was analyzed to record total phenolic and total flavonoid contents.
