Jan 3, 2022 · Egg Yolk Agar, modified is based on the original formula for Egg Yolk Agar developed by McClung and Toabe for the isolation and differentiation of organisms based on Lecithinase and lipase production and proteolytic activity.
May 16, 2024 · Egg Yolk Agar Base is a slight modification of the original McClung Toabe Agar Base, which is used for the isolation and detection of Clostridium perfringens. The modification involves the addition of hemin to the base.
Sep 7, 2023 · Egg Yolk Agar (EYA) is a microbiological growth medium containing agar and egg yolk, used to assess the lipolytic activity of microorganisms, particularly bacteria, by detecting their ability to hydrolyze the lipids in egg yolk.
Jan 7, 2022 · The egg yolk additive, in addition to providing enrichment, aids in the identification process by demonstrating lecithinase activity (egg yolk reaction). A clear zone and grey-black colonies on this medium are diagnostic for coagulase positive Staphylococci.
Anaerobic Egg Yolk Agar contains egg yolk emulsion which allows for the detection of lecithinase and lipase activity in Clostridium spp. 4 The degradation of lecithin in the egg yolk results in an opaque precipitate around the colonies. The lipase enzyme hydrolyzes the fats within the egg yolk, which results in an iridescent sheen on the colony ...
