Eosin methylene Blue Agar contains peptone (a sugar of glucose), lactose, sucrose, and the dyes eosin Y and methylene blue. The sugars provide fermentable substrates to encourage growth of fecal coliforms. The dyes inhibit growth of Gram-positive organisms.

What is the function on bile in Eosin Methylene Blue agar?
To make the Eosin Methylene BLue Agar look cool and hip.
What function of emb agar?
function of eosin methylene blue agar (EMB)
What is EMB agar?
Eosin Methylene Blue Agar (EMB) was developed by Holt-Harris and Teague.1 This formula contains lactose and sucrose with two indicator dyes, Eosin Y and Methylene Blue. The use of Eosin Y and Methylene Blue as indicators produced sharp and distinct differentiation between colonies of lactose fermenting and nonfermenting organisms. Sucrose is included to detect coliforms that ferment sucrose more readily than lactose. EMB Agar is selective due to the presence of an inhibitor and differential based on the ability of some organisms to ferment carbohydrates with the absorption of an Eosin Y and Methylene Blue complex.
Will staph grow on EMB agar?
No, it will not. Methylene blue agar is used to identify gram negative bacteria, staphylococcus is gram positive.
What are the Biochemical tests for identification of Ecoli?
EMB (Eosin Methylene Blue) AgarThis agar plate is selective for gram-negative bacteria (one of which is E. coli). A characteristic green sheen along the streak will identify it as E. coli after a 24-48 hour incubation period. This is due to its lactose-fermenting properties which ellicits a green sheen.

Quantity of lactose in levine eosin methylene blue agar?
Levine eosin methylene blue agar does not contain lactose. It is a selective and differential medium used for the isolation and differentiation of gram-negative enteric bacteria based on their ability to ferment lactose. The agar contains lactose as a substrate for fermentation, but the actual quantity of lactose present in the agar may vary depending on the manufacturer and the specific formulation of the medium.

State the usefulness of EMB agar?
EMB agar or Eosin methylene blue agar is to see which gram negative is lactose fermenters by colonies appearing a purple, black color. It also inhibits the growth of gram positive bacteria.
Will staph grow on EMB agar?
No, it will not. Methylene blue agar is used to identify gram negative bacteria, staphylococcus is gram positive.
What is Eosin Dye?
It is a dye found in Eosin-methylene blue (EMB) agar, which permits the differentiation between enteric lactose fermenters and nonfermenters. The dye methylene blue inhibits the growth of gram positive bacteria. While the eosin acts as a pH indicator, measuring the levels of acid production due to the fermentation of lactose.Eosin is a stain that is used for staining the cells to observe the structurea nd number of cells. It is an acidophilic stain.
Why glycerol is added in cetrimide agar?
as a source of carbon which important for bacterial growth
What ingredients of EMB agar inhibit the growth of gram positive organisms?
methylene blue
What is an agarase?
An agarase is an enzyme found in certain bacteria which allows them to use agar as their primary source of carbon.
