Abstract

The good capability of zinc-tolerant probiotic of Lactobacillus plantarum tolerating high concentrations

of Zinc+2 and producing Zinc Oxide Nanoparticles highlights the unique characteristics of these

bacteria as a natural microbial cell nano-factory for a more efficient and environmentally friendly

process of biosynthesis of these nanoparticles. The morphological and structural properties of Zinc Oxide

Nanoparticles were determined by X-ray diffraction, Atomic Force Microscope and Field Emission Scanning

Electron Microscope showed that the synthesized nanoparticles were crystalline, moderately stable, roughly

spherical, hexonal in shape and pure

We examined the antibacterial activity of the Zinc Oxide Nanoparticles and Zinc Oxide Nanoparticles/

Poly-?- hydroxybutyrate bionanocomposite on some pathogenic bacteria .It is clear in this the study that

Zinc Oxide Nanoparticles/Poly-?-hydroxybutyrate bionanocomposite has stronger inhibitory effect on

pathogenic bacteria compared with Zinc Oxide Nanoparticles only because the bionanocomposites exhibited

reduced water uptake and superior gas as well as vapour barrier properties and causes increasing damage of

the pathogenic bacteria.
