0.1% Peptone Salt Diluent

Principle
Peptone Salt Diluent is composed of peptone and sodium chloride. Peptone, serves the simplest source of the
nitrogen, carbon and other growth factors such vitamins. 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. It is
recommended by ISO Committee (1) for use as an isotonic diluent and used as a diluent for carrying out
dilutions of different samples.
Use: Recommended by ISO Committee for use as an isotonic diluent for food samples and used as a diluent
for carrying out dilutions of different samples.
