THE EFFECT OF SOME NANOPARTICLES ON RHODOTORULA SP.

Abstract

Numerous nanoparticles have the ability to inhibit the growth of bacteria, fungi, and viruses. such as Nanoparticles of gold and silver. It affects these microbes' cell membranes, which results in cell death .Aim of study the study aimed to find the difference between the influence of silver nanoparticles and gold nanoparticles on  inhibit growth of the isolated Rhodotorula yeast , After we isolated Rhodotorula yeast from affected patients and its microscopic and phenotypic diagnosis. We investigated the differences between effect of the two types of nanoparticles used by measuring the inhibition zone for fungal growth using the drilling method at three different concentrations: 1%, 2%, and 4% of silver and gold nanoparticles. It was discovered that the inhibitory effect on fungal growth increased with the concentration of these components. After comparing the two types' effects, we discovered that the effect of silver (Ag-Nps ) concentrations was more effective than that of gold nanoparticles (Au-NPs) at inhibition  Rhodotorula from growing.
