7. Catalase: This experiment tested for the presence of the enzyme Catalase, and determine the morphology of the unknown bacteria. The bacteria were streaked on a plate of nutrient agar and incubated at 37-degree Celsius. After incubation, several drops of hydrogen peroxide were added to the colony. The formation of gas bubbles is a positive test for catalase.
