Sep 29, 2018 · Levine EMB (eosin methylene blue) agar is an example of a selective and differential medium. This means that only some bacteria will grow on this agar and that the appearance of those that do grow will be different. In particular, EMB agar inhibits the growth of Gram-positive bacteria and helps differentiate some of the Gram-negative rods.

The mechanism involved in the action of eosin-methylene blue agar (EMB) in differentiating Escherichia coli from Enterobacter aerogenes was investigated using prototrophic strains of these organisms and a Lac − auxotroph, E. coli X-961. The final pH of the EMB agar resulting from growth of these organisms at the expense of lactose was shown to play a critical role in the differential action.

Eosin Methylene Blue Agar. Eosin methylene blue agar (EMB) is a selective and differential medium used to isolate fecal coliforms. Eosin Y and methylene blue are pH indicator dyes which combine to form a dark purple precipitate at low pH; they also serve to inhibit the growth of most Gram positive organisms. Eosin methylene blue - Wikipedia Eosin methylene blue (EMB, also known as "Levine's formulation") is a selective stain for Gram-negative bacteria. EMB contains dyes that are toxic to Gram-positive bacteria. EMB is the selective and differential medium for coliforms. It is a blend of two stains, eosin and methylene blue in the ratio of 6:1. 23: Eosin Methylene Blue Agar (EMB) - Biology LibreTexts EMB contents. EMB contains lactose and sucrose sugars, but it is the lactose that is the key to the medium. Lactose-fermenting bacteria (E. coli and other coliforms) produce acid from lactose use, and the combination of the dyes (which serve as pH indicators in this medium) produces color variations in the colonies because of the acidity.
