Starch hydrolysis reaction
Webb1 juli 2006 · Starch is hydrolysed using a dry matter content of about 35% initially. During the hydrolysis reaction, a certain amount of water is consumed. The theoretical amount of water that is required for complete hydrolysis of starch to glucose is defined to as chemical gain ( Marchal & Tramper, 1999 ). WebbThe B. subtilis produced a clear zone around the growth which is a positive reaction (Fig. 1.) and indicates that the starch has been removed in the area around the bacterial inoculum . B. subtilis produced the enzyme amylase which hydrolyzed starch in the agar.

To detect the hydrolysis of starch, Gram’s iodine (I 2KI solution or Lugol's iodine) is used. Gram’s iodine reacts with starch to form a dark blue, purple, or black complex depending upon the concentration of iodine.
