EMB Agar: Composition, Principle, and Colony Morphology
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.

2022年3月7日 · The eosin methylene blue agar (EMB agar) is a selective staining for gram-negative bacteria. It contains two dyes in the ratio of 6:1 and is both toxic to gram-positive microorganisms. It is both a selective and differential mediums for coliforms.
Eosin-methylene blue (EMB) agar was first developed by Holt-Harris and Teague in 1916. They used EMB agar to clearly differentiate between the colonies of lactose fermenting and nonfermenting microbes.
