Final answer:
The Starch Hydrolysis Test uses an agar medium containing starch, with iodine solution added to detect starch breakdown by hydrolysis, indicated by a lack of blue-violet color around bacterial growth.
Step-by-step explanation:
The medium used in the Starch Hydrolysis Test is agar containing starch. This test assesses the ability of microorganisms to hydrolyze starch. The process can be visualized by adding iodine, which forms a complex with the starch, resulting in a characteristic blue-violet color. If the starch has been hydrolyzed by the enzymes (like amylase) produced by the bacteria, there will be clear zones around the bacterial growth where the iodine does not change color, indicating starch breakdown.
In the procedure for Testing for Carbohydrates: Starches, following laboratory safety procedures such as wearing goggles is crucial. In this test, the addition of iodine solution to a starch solution and the subsequent observation of color change serve as an indicator of the presence of starch.
