Medium is prepared according to the formulation of Eloy and Lacrosse and is a selective medium that supports good growth and differentiation of thermophilic lactobacilli and streptococci in yoghurt products. Yoghurt is a fermented milk product in which Streptococcus thermophillus and Lactobacillus bulgaricus are the essential microbial species and are active in a symbiotic relationship.
