What conclusion can you draw when an experimental sample gives both a positive starch and a positive maltose test after incubation?
The maltose positive test will have a degree of how positive, it is. That will tell you how much of the starch has been digested.

Starch digestion (hydrolysis) is incomplete
What compound is produced as a result of mixing amylase with an aqueous solution of starch?
Maltose. Water and Starch mixed with amylase makes maltose
Why would a negative iodine test for starch indicate a positive result for the enzymatic degradation of starch by amylase?
Perhaps the iodine solution was old and gave a false negative.
What is maltose dextrin?
dextrine and maltose are byproduct of starch when starch is completely hydrolized it gives dextrin and maltose
Is bacillus subtilis positive or negative for starch hydrolysis?
it is positive for starch hydrolysis
Which enzyme converts starch into maltose?
Amylase catalyses starch into maltose.
Function of maltose?
The main function of maltose is to digest starch . Starch is commonly used in plants to store glucose and maltose will serve as the intermediary product of the digestion of starch.
Is E. coli positive or negative for starch agar test?
E.coli does not digest the starch on a starch agar plate, therefore it does not produce amylase making it negative.
What are the degradation products of enzymatic hydrolysis of starch?
Stages in the hydrolysis of starch: starch -> soluble starch -> amylodextrin -> erythrodextrin -> achrodextrin -> maltose -> glucose
Is Pseudomonas aeruginosa positive for starch hydrolysis?
no it is negative
If we chew rice or bread for a few minutes it starts tasting sweet?
When boiled rice is chewed, the salivary amylase of the saliva changes the starch to maltose. Thus it tasted sweet and gave a negative result with iodine.Thanks
