Principle and Interpretation
Standard Nutrient HiVeg Agar is prepared by using HiVeg peptone No. 1 and HiVeg extract which are of vegetable origin and free from BSE/TSE risks. Standard Nutrient HiVeg Agar is the modification of Standard Nutrient Agar which is formulated as per the recommendation of APHA as a general purpose medium for the cultivation of non-fastidious organisms from water and wastewater, dairy and food products (1, 2).
HiVeg peptone No. 1 provides amino acids and large chain peptides. HiVeg extract provides water soluble substances like carbohydrates, vitamins, organic nitrogen compounds and salts. Sodium chloride maintains osmotic equilibrium.
