[objective]To determine the antibacterial activity of Curcumin in vitro.[Method]Minimal inhibitory concentration(MIC) and inhibition zone were used to evaluate the antibacterial activity of curcumin in vitro.[Result]The experiment results showed that MIC of curcumin on Bacillus Subtilis,Salmonella ψ and Staphylococcus aureus were 0.100 0,0.200 0,0.100 0 g/ml,respectively,while no obvious antibacterial activity were detected of Escherichia coli,Penicilliums,Trichoderma and Aspergillus niger.Diameter of inhib...
