Abstract

This study aims to show the effect of glucoamylase and glucose oxidase from the Aspergillus niger and Penicillium notatumrespectively on inhibition of Streptococcus mutans causes the dental caries. The result of this study recorded theStreptococcus mutans growth was inhibited in the using the first and the second concentration of glucoamylase and glucose oxidase (0.09,0.009 and 0.3,0.03 μl) respectively, while the growth was appered in third concentration of enzymes (0.0009, 0.003 μl) respectively, the NaF, ZnF2, C12H7 Cl3 FNaO2, NaCl, NaHCO3 and KSCN with (0.5 and 1M) leads to increase the enzymes activity, while Na3PO4, SrCl2, Fe2O3 and Ca(HCO3) 2 caused decreased the activity of enzymes when treated with (0.5 and1 M) from these solutions, the glucoamylase activity also decreased when it treated with (0.5 and 1M) from KNO3 solution but this solution increased the activity of glucose oxidase when it treated with (0.5 and 1 M) from this solution.
