The effect of Zinc Oxide nanoparticles and ethanol extracts of Hyssop (Hyssopus officinalis) on the growth of Saccharomyces cerevisiae

According to investigations, Zinc oxide nanoparticles were found to be highly effective against microorganisms. Also an antibacterial and antifungal effects have been reported about Hyssop extracts, as well. In this study the effect of zinc oxide nanoparticles and Hyssop extract, individually and in combination mode against single cell Saccharomyces cerevisiae were examined. In order to make organic Nanoparticle product, the extract of Hyssop was combined with nanoparticles of zinc oxide which was promoted next. The results showed that in single mode Hyssop plant extract was effective at concentrations 0.02 mg per ml concentration and gradually increasing the concentration reduces the number of yeast cells (p <0.05). Also 0.005 mg per ml of the nanoparticles could gradually reduce the number of yeast cells. Also, this study showed that the nanoparticles in the Middle 0.04 mg per ml concentrations re-stimulate significantly the growth of yeast cells (p<0.05). The study revealed that nanoparticles of zinc oxide at concentration of 0.04 and 0.06 mg per ml stimulate the growth of the yeast cells (p<0.05). Nano-particles in the concentration of 0.0016 mg per ml Zinc oxide plus 0.0012 mg per ml of the extract of plant Hyssop gradually reduced the number of yeast cells (p <0.05). The yeast cells stimulation by concentration of 0.04 mg per ml Nanoparticles plus 0.03 mg per ml of the herbal extract was seen in this study (p<0.05).
