4 Ιαν 2022 · Eosin Methylene Blue (EMB) agar is a differential microbiological medium, which slightly inhibits the growth of Gram-positive bacteria and provides a color indicator distinguishing between organisms that ferment lactose (e.g., E. coli) and those that do not (e.g., Salmonella, Shigella).
Eosin Methylene Blue (EMB) agar is a selective and differential culture medium. It selectively promotes the growth of Gram-negative bacteria and aids in the differentiation of lactose fermenter and non-lactose fermenting colonies. EMB Agar is used for the isolation of fecal coliforms.
Eosin Methylene Blue Agar Levine is used for the isolation and differentiation of Gram-negative enteric bacilli and is not intended for use in the diagnosis of disease or other conditions in humans.

25 Μαΐ 2023 · EMB agar, also known as Eosin Methylene Blue agar, is a specialized microbiological medium that plays a crucial role in the isolation and differentiation of gram-negative bacteria. Its unique composition and properties make it a valuable tool in the field of microbiology.
Theory. EMB agar contains peptone, lactose, sucrose, and the dyes eosin Y and methylene blue; it is commonly used as both a selective and a differential medium. EMB agar is selective for gram-negative bacteria.
Principle. Eosin Methylene Blue agar (EMB agar) is both selective and differential culture medium ideally used for isolating faecal coliforms. It is a selective medium due to inhibition of gram-positive bacteria by methylene blue. EMB agar’s differential property comes from the eosin and methylene blue complex formation under acidic pH.
