Biocidal action of metal (Mg/Cu/Ni/Zn) doped strontium formate dihydrate crystal against bacterial and fungal strains

Strontium formate dihydrate crystal was grown and Mg, Cu, Ni and Zn metal were doped into the newly grown strontium formate crystal. The pure and metal doped crystals were characterized by EDX, FT-IR and XRD spectroscopic methods. Their antimicrobial activities have been investigated against the series of bacterial and fungal strains. The biocidal activity of pure and doped strontium formate crystals was compared. The effects of dopant concentration on the biocidal activity of the crystals have been also reported. Increase in dopant concentration inside the crystal lattice was resulting in the increase of antimicrobial activity of the crystals.
