Citrate Azide Agar 500G

Citrate Azide Agaris recommended for selective cultivation of Enterococci in dairy products.Tryptone and yeast extract in the medium provide nitrogen, carbon, long chain amino acids, vitamins and other essential growth nutrients. The high concentrations of sodium citrate inhibit the growth of the accompanying microbial flora. Tetrazolium blue is reduced by Enterococci to form blue coloured colonies. Sodium azide helps in the selective isolation of Enterococci.
