Background. Skin infections occur commonly and often present therapeutic challenges to practitioners due to the growing concerns regarding multidrug-resistant bacterial, viral, and fungal strains. The antimicrobial properties of zinc sulfate and copper sulfate are well known and have been investigated for many years. However, the synergistic activity between these two metal ions as antimicrobial ingredients has not been evaluated in topical formulations. Objective. The aims of the present study were to (1) formulate topical creams and gels containing zinc and copper alone or in combination and (2) evaluate the in vitro antibacterial activity of these metal ions in the formulations. Method. Formulation of the gels and creams was followed by evaluating their organoleptic characteristics, physicochemical properties, and in vitro antibacterial activity against Escherichia coli and Staphylococcus aureus. Results. Zinc sulfate and copper sulfate had a strong synergistic antibacterial activity in the creams and gels. The minimum effective concentration was found to be 3 w/w% for both active ingredients against the two tested microorganisms. Conclusions. This study evaluated and confirmed the synergistic in vitro antibacterial effect of copper sulfate and zinc sulfate in a cream and two gels.

Streptomyces Tendae

Geosmin is produced by several phototrophic and heterotrophic taxa. This secondary metabolite can impart an earthy taste and odor to water resources. To reduce algal populations and associated biosynthesis of geosmin, copper sulfate and other copper-containing algicides are often applied to aquatic systems. Cultures of the bacterium Streptomyces tendae and the fungus Penicillium expansum grown on increasing concentrations of copper sulfate accumulated more biomass than untreated controls, indicating that these heterotrophic cultures were not markedly susceptible to this algicide. Cultures of Streptomyces albidoflavus treated with increasing concentrations of copper sulfate accumulated less biomass than untreated controls. However, copper-treated mycelium of each taxa investigated contained greater concentrations of geosmin than untreated controls. In addition, there was not a significant interaction between in the amount of biomass or geosmin accumulated by cells exposed to 0 and 0.5 mg l−1 copper sulfate over increasing dosages of zinc sulfate. If field populations exhibit similar responses, application of copper sulfate to aquatic systems may contribute to geosmin biosynthesis by certain taxa.

Zinc Concentrate

The mixed concentrate which contains 9.97% Cu, 9.25% Zn and 38.62% S is selected from polymetallic sulfide ores in Kazakhstan. The difficulty of study is the effective separation of copper and zinc. We used the process of grinding the mixed concentrate, and then carried out separation flotation of copper, zinc and sulfur according to the properties of the mixed concentrate. Considering the poor effect of single depressant, we used the combination of zinc sulfate and sodium sulfite as the depressants for separating copper. The collector of copper floatation is 432-xanthate and the activator of zinc floatation is copper sulfate. As a result, we obtained satisfying selecting targets through closed-circuit test: The grade of copper is 21.91% and zinc is 6.95% in the copper concentrate. The copper recovery is 87.64%. The grade of zinc is 40.42% and recovery is 65.80% in zinc concentrate. The sulfur recovery is 46.39% in sulfur concentrate.

Franke (Znb. F. Chir. 1924; according to the ref. In "Practice. Time", 1924, No. 7-8) praises the stubbornly not healing tuberculous fistulous passages cauterizing them with a mixture of solutions of copper sulfate and zinc sulfate (6.0 by 88.0 water). These moxibustion is repeated after 3-4 weeks. To protect the skin, it is smeared with petroleum jelly.
