  • Nutrient medium Kessler, 250 gr

Kessler's medium is used to detect E. coli in the sample. This is achieved through two factors of the nutrient medium. First, the presence of bile suppresses the concomitant non-pathogenic microflora, the crystalline violet suppresses gram-positive bacteria, and lactose as the only source of carbon suppresses bacteria that can not ferment it. Secondly, the use of a glass float allows us to clearly identify the presence of coliforms on the basis of gas release.

Purpose: Detection of coliform bacteria

Principle of action: The selective properties of the Kessler environment are due to bile and crystalline violet. The only carbohydrate in the environment - lactose. With the help of a glass float, it is possible to detect the release of gas characteristic of coliform bacteria.

Storage:

Lactose - 10 g / l

The peptone is enzymatic - 10 g / l

The bile is 3 g / l

Crystal violet - 0.015 g / l

Instructions for use:

1. Dissolve 23 g of medium when heated in 1 liter of purified water.

2. Boil 2-3 minutes, until the components are completely dissolved.

3. Pour into glass flask test tubes and autoclave for 20 minutes at 112 C

PH level: 7.5-0.2 ° at 25 ° C

Delivery time: 5 d.
