Agar Medium F is a selective medium, recommended for detection and enumeration of Enterobacteria in accordance with British Pharmacopoeia. It is also referred to as Crystal Violet, Neutral Red, Bile Agar with Glucose. Mossel et al added glucose to the medium after observing an improved detection of coliforms. Incubation can be carried out at different temperatures and incubation time depending upon the group of Enterobacteriaceae to be recovered. Gelatin and yeast extract provide nitrogenous and carbonaceous compounds, long chain amino acids, vitamins and other nutrients essential for bacterial metabolism. The presence of the inhibitors along with bile salts and crystal violet makes this media selective. Crystal violet inhibits gram-positive organisms especially Staphylococci. Neutral red indicator helps to detect lactose monohydrate and glucose monohydrate fermentation. Sodium chloride aids in maintaining the osmotic equilibrium in the medium. The red colour is due to absorption of neutral red and a subsequent colour change of the dye when the pH of medium falls below 6.8.
