| Protocol | In Vitro | The inhibition of bacterial growth by Rifamycin SV is due to the production of active species of oxygen resulting from the oxidation-reduction cycle of Rifamycin SV in the cells. The aerobic oxidation of Rifamycin SV to Rifamycin S is induced by metal ions, such as Mn2+, Cu2+, and Co2+. The most effective metal ion is Mn2+ |
