Abstract: The polyoxometalates α-1,2,3-K6H[SiW9V3O40], α-1,2-K6[SiW10V2O40] and α-K5[SiW11VO40] (abbreviated as α- SiW9V3, α-SiW10V2, α-SiW11V, respectively) were synthesized and characterized by UV-Vis and FT–IR spectrums. The antibacterial activity of four polyoxometalates against common bacteria(Escherichia coli, Bacillus subtilis, yeast, Aspergillus niger and Penicillium) was studied by disk diffusion method. The results indicated that four compounds showed different antibacterial effects on Escherichia coli, Bacillus subtilis, yeast, Aspergillus niger, and the antibacterial activity of Penicillium was relatively worse. This study should give theoretical support for polyoxometalate used as a fruit and vegetable preservative agent.
