It is the best nutrient medium for the growth of various organisms from microbes to large animals. Nearly all the changes which take place in the flavour and appearance of milk, after it is drawn, are the result of the activities of micro-organisms. In the present paper antibacterial activity of different milk samples i.e. buffalo milk , camel milk, cow milk and soya milk have been carried out on Staphylococcus aureus. Milk samples were subjected for various treatments. Comparable studies between direct milk, ordinary solution of milk and micellar solutions of milk have been carried out. Micellar system of milk shows highest antibacterial activity as compared to other treatments. https://www.biotech-asia.org/vol10no1/antibacterial-activity-of-milk-samples-under-different-conditions/ Antibacterial activity; Milk; Micellar medium; Staphylococcus aureus
