Figure 8 Casey da 21 J Rruhtelis SU The starch agar plate test is to determine the ability of an organism to hydrolyze starch, base on their alpha amylase enzyme activity. Iodine is added as an indicator after incubation because there was no color change when the organism hydrolyses starch. It creates a clear zone around the bacteria. . However, there was no yellow glow appearing on it because the tests were not done on the MSA and because the bacteria hydrolyzed starch. Hence, show a negative result for starch hydrolysis. The halo was not able to glow because the organism did not ferment mannitol. The milk agar test the ability of an organism to produce exoenzyme casease that hydrolyze casein. On the milk agar plate the organism was able to break the casein we were able to see the halo appearing around the organism that has grown.
