Autoclave for about 15 minutes at 121 degree Celsius. Transfer the blood agar base to the water bath at a temperature of 50°C. Once the base has cooled down, start adding sterile blood agar (5% of defibrinated blood) and mix well to prevent the formation of air bubbles. Dispense about 15 ml to a sterile petri plate. 7. Observe the medium surrounding colonies in the plate. The culture showing a darkening or discoloration of the medium in the vicinity of growth demonstrates alpha-hemolysis. Cultures showing clear halos around colonies and under growth is exhibiting beta-hemolysis. 8. Record test result. Uninoculated Blood Agar Plate. .
