The uninoculated Kligler Iron Agar media is typically a red color, reflecting the presence of peptones and sugars in the medium.
simply agar medium
E. coli produces a green color on EMB (Eosin Methylene Blue) agar due to the fermentation of lactose and the production of acid, which leads to a change in the pH of the medium. The methylene blue dye in the agar interacts with the acidic environment created by the fermentation, resulting in a greenish metallic sheen on the colonies. This characteristic color helps differentiate E. coli from other bacteria on the medium.
Differential medium.
The color of salmonella in bismuth sulphite agar is brown to black color with metallic sheen.
It is a medium that support the growth of cells or microorganisms. It is usually a liquid or a gel and there are different agar mediums for different types of cells.
To determine how much agar is needed for 300 ml of medium, we can use a proportion based on the agar quantity provided for 1 liter. 6.4 g agar is used in 1 liter, which means for 300 ml, we can calculate: (6.4 g / 1000 ml) * 300 ml = 1.92 g of agar. Therefore, 1.92 g of agar is needed for 300 ml of the medium.
A concentration of 0.5-0.7% agar is typically used in semisolid medium for motility. This is lower than the typical 1.5-2% agar concentration used in solid medium, allowing motile bacteria to move more easily through the softer semisolid medium.

In our lab we use LB agar, LB broth, and 2XYT broth.
