Later on it was modified to the present composition for the cultivation and enumeration of bacteria in air, water, milk and dairy products. Various authors have studied different aspects of this medium like study of thermophilic bacteria in milk, influence of incubation temperature etc. It is used as a standard medium for the bacteriological plate count of milk and dairy products.
