0.1% Peptone Salt Solution

0.1% Peptone Salt Solution is recommended as diluent for different test method.is recommended as a diluent for dilution of sample by different test methods. It is widely used for examination of foodstuffs. This medium is also recommended by ISO Committee (ISO) i.e SO/DIS 6649. for use as an isotonic diluent. It contains peptone at low concentration which provides nutrients for survival of microorganisms and hence protecting the organisms. Sodium chloride at 0.85% concentration maintains osmotic balance of medium thereby maintaining cell morphology and integrity. The pH of this diluent medium is near neutral range optimum for viability of microorganisms.Therefore it can be successfully used as a diluent for carrying out dilutions of different samples.
