General description

Nutrient medium is a general basic culture medium for less fastidious microorganisms. Meat extract, yeast extract and peptone provide nitrogen, vitamins, amino acids and carbon for growth. Sodium Chloride ensure osmotic balance. Thus, when adding blood, as supplement the blood cells will not rupture. Addition of 10% different biological fluids such as blood, serum and egg yolk makes it suitable for the cultivation of related fastidious organism. Acc. to Gray et al. the addition of 0.05% potassium tellurite makes the Nutrient medium an excellent enrichment medium for Listeria monocytogenes.
