The protein casein exists as a colloidal suspension in milk and gives milk its characteristic white, opaque appearance. If the casein in the milk is hydrolyzed into peptides and .This medium is used to determine if an organism can hydrolyse casein. A clear zone around and under the colonies indicates hydrolysis has taken place.30: Casein Hydrolysis Procedure of Casein Hydrolysis Test. Use a pure culture of the test isolate to heavily inoculate a 10 mm square of the Casein Agar surface. Press the inoculum into the surface of the agar to make sure it stays there. Use cellophane tape, Shrink-Seals, or a strip that lets gas through to seal the plate.
This video covers the casein hydrolysis test for General Microbiology Lab (Biology 210L) at Orange Coast College (Costa Mesa, CA).
Casein Hydrolysis Test Objective: To demonstrate the ability of certain microorganisms to produce extracellular enzymes, capable of degrading the milk protein casein. . Casein hydrolysis is . Casein Hydrolysis (Skim milk) Purpose: To detect the production of casease. Media: Skim Milk Agar . Mechanism/reactions: Casease proteolyses casein into peptides and amino acids. Directions: Streak agar in a straight line and incubate for 24 – 48 hours. Figure \(\PageIndex{4}\): Skim milk test, positive(L), negative (R) Interpretation:casein hydrolysis test. what is the purpose of this test? -to test the ability of different bacteria to degrade casein into amino acids by producing the proteolytic enzyme called casease. Casein Hydrolysis Test Procedure. Initially the organisms are inoculated on the plate either in a form of straight line or in a zig zag manner. The plate is incubated at a temperature of about 25 to 37ºC. Then the milk agar plate cultures for examined for the presence or absence of a clear area or for the formation of zone of proteolysis .physiol. 348 Hydrolysis of Casein several determinations give 4.5 per cent. Three separate determinations of tyrosine which we have made after boiling with 25 per cent sulphuric acid for twenty-four, thirty-six, and twenty hours respectively gave 3.9, 3.2, and 3.4 per cent of the moistureand ash-free casein.
