A POTENTIAL EFFECT OF SILVER NANOPARTICLES(Ag-NPs) ON SOME LACTIC ACID BACTERIA GROWTH

Document Type : Original Article

Abstract

This study aimed to essay what could happen if lactic acid bacteria,especially some antifungal lactobacilli strains, mesophilic and thermophilicstarter cultures (G+ve model), were treated with Ag-NPs using standard platecount agar assay. As well,E coli (G-ve model) was treated with Ag-NPs in abroth medium. The turbidity was measured for zero, three, six, nine hours andcompared to control. The results approved that Ag-NPs had a negligible effectthe G+ve strains. On the other hand, Ag-NPs had an aggressive activityagainst the gram-negative one.
