Why is it important to first determine whether growth occurred in a differential medium such as a starch agar before examining the plate for starch hydrolysis?
I do not know precisely what this is used for but starch agar is usually used to test whether the cultured cells produce amylase. In a teaching-experiment setting if no growth occurred then there really is no point to check whether the cells produced amylase or not since they probably didn't survive, and dead cells don't produce amylase. Any hydrolysis detected with iodine solution would be caused by stray enzymes such as those in a drop of saliva.i dont know go find out
