Antibacterial Activity Assessment of Bi₂WO₆/Ag₃PO₄/Ag Photocatalyst and <i>Persian</i> <i>Oak fruit</i> Phytobiotic

Abstract

The antibacterial effect of the previously reported Bi2WO6/Ag3PO4/Ag Z-scheme heterojunction photocatalyst compared with a phytobiotics named, aqueous extract of Persian Oak fruit. The impact of both materials on the expression of the urease gene was checked in two kinds of samples such as clinical and standard Helicobacter pylori (H. pylori). The gene expression differences were collected by real-time PCR from clinical strains and the standard of H. pylori as well as the MIC and MBC were found to be 3.1 and 0.8 mg/mL, and 6.2 and 1.6 mg/mL, for Bi2WO6/Ag3PO4/Ag photocatalyst and Oak fruit Phytobiotics, respectively. Due to the impact of Oak fruit extract on the urease gene of H. pylori, it is possible to use it as a disinfector against this bacterium and the proposed photocatalyst, for efficiently purifying H. pylori bacteria from contaminated environment.
