For pre-enrichment of Salmonella spp.
Principle:
Peptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride maintains osmotic equilibrium; potassium dihydrogen phosphate and disodium hydrogen phosphate as buffer.
Formulation(per liter):
Peptone: 10g
Sodium chloride:5g
Disodium hydrogen phosphate:3.5g
Potassium dihydrogen phosphate: 1.5g
Final pH7.2 ± 0.2
