It indicates that bacterium had used their alpha-amylases enzyme to break down the starch moleculeyieldingdextrins, maltose and glucose. On a petri-dish, apositivehydrolysis is shown by clear (white) halo. Negative hydrolysis is shown by purple tobrowncolor.

What chemical test is performed to indicate the completion of the hydrolysis of starch by acid?
If using acid-catalyzed hydrolysis of starch you can tell the hydrolysis is complete with the solution no longer gives a bluish/purple color with iodine solution. The color should be colorless.
Chemical reaction by which starch is split into mono-saccharides?
Hydrolysis. This process uses water to break down molecules such as starch.
Polysaccharides are split apart to form monosaccharides in a reaction called?
This is a smart question. But the answer is simple it is a hydrogen reaction. - Hydrolysis.
What is the product of the hydrolysis of glycerol tristearate?
glyceryl tristearate product of hydrolysis
What are the disaccharide product of the hydrolysis of starch?
Maltose

Is bacillus subtilis positive or negative for starch hydrolysis?
it is positive for starch hydrolysis
In which reaction mixture did hydrolysis of starch occur?
The Starch Hydrolysis by Amylase is the reaction mixture that leads to the hydrolysis of starch. This usually occurs during the metabolic reactions.
Does ecoli hydrolysis starch?
no
What are the degradation products of enzymatic hydrolysis of starch?
Stages in the hydrolysis of starch: starch -> soluble starch -> amylodextrin -> erythrodextrin -> achrodextrin -> maltose -> glucose
Chemical reaction by which starch is split into mono-saccharides?

What is the product of the hydrolysis of glycerol tristearate?
glyceryl tristearate product of hydrolysis
What enzyme begins the hydrolysis of starch?
ptyalin
What are the disaccharide product of the hydrolysis of starch?
Maltose
How can you tell when hydrolysis of starch is complete?
If using acid-catalyzed hydrolysis of starch you can tell the hydrolysis is complete with the solution no longer gives a bluish/purple color with iodine solution. The color should be colorless.
How would the results of the starch hydrolysis change if glucose was added to the medium?
The starch is a different media. Therefore, by adding glucose to the medium it would throw off the results of the starch hydrolysis significantly.
