Q.2
Medium used in the starch hydrolysis is Amylase , which
break hydrolyzes some of the bonds between glucose subunit which help bacteria break down starch.
Starch on starch agar plate.
Added iodine to plate after incubation . The iodine form a dark blue / black complex with starch but remains its original amber color in the absence of starch.
positive Starch Hydrolysis test look like.
After incubation and the iodine is added the iodine will remain its original amber color around the bacteria that has the enzyme Amylase.
Reagent used.
Gram iodine.
So answer will be.
Gram iodine / an area of blue - purple staning.
