A combination of tryptone and soya peptone provides essential nutrients for the growth of test organisms. Dextrose provides a carbon source and enhances the growth of test organisms. Phosphates in the medium enhance buffering action and sodium chloride maintains osmotic equilibrium. Polymixins are reported to have slow diffusion in agar giving a smaller zone of inhibition.
