Egg Yolk Emulsion is used as supplement in nutrient agars for detection of lecithinase activity in microbial colonies. Herewith, bacterial species like Bacillus cereus and Clostridium perfringens, or Staphylococcus aureus may be identified. The lecithinase activity can be noted by formation of light, sometimes whitish halos surrounding the colonies.
