Lab Day 8

Lab Day 8

Today in lab, we observed our results from the tests we did the day before.
MacConkey Agar: the results of this test was that the strand of bacteria turned a bright pink color meaning it was a positive test. Our bacteria is a lactose fermenter.

Eosin Methylene Blue Agar (EMB): The strain of our bacteria was a green color meaning our bacteria was a strong lactose fermenter. If it was pink color, it would mean our bacteria was a weak lactose fermenter.

Mannitol Salt Agar: This test tests for staphylococcus which means only halophiles would appear positive and the color would turn yellow. Our bacteria was negative for halophiles therefore it is not staphylococcus and our bacteria does not ferment mannitol.













Phenylethyl Alcohol Agar (PEA): Our bacteria is gram negative therefore, it won’t grow on the PEA agar.

Blood Agar: The result of our test was that the bacteria turned green which means it was alpha-hemolitis. This means our bacteria was partial hemolysis and you can use this test to test for strep.
