You will be putting a drop of hydrogen peroxide on the edge of your plate as one of many tests used to identify bacteria. If it bubbles, this means that: a. it is a negative reaction, meaning that catalase is present b. it is a positive reaction, meaning that catalase is present c. it is a negative reaction, meaning that catalase is not present d. it is a positive reaction, meaning that catalase is not present
